Motion Platform for Industrial Testing
CSCMotion engineers electric 3DOF and 6DOF motion platforms around the test article, fixture, center of gravity, motion profile, duty cycle, control interface and acceptance method. The result is a motion subsystem defined for the test—not a generic platform selected from payload alone.
Normal supply scope: motion platform, controller, electrical system, agreed platform interfaces and platform-level FAT. DUT instrumentation, the test standard, pass/fail criteria and system-level data analysis remain with the customer or test-system integrator unless included in our written proposal.
3DOF & 6DOF
Custom load case
Recorded or real-time input
Project-defined FAT
Start with test-method fit
Turn Motion into a Controlled Test Input
An electric motion platform is one way to expose a test article to repeatable motion. We first determine whether position and orientation reproduction is the right method for the required load, dynamics and evidence.
A CSCMotion platform may fit when
The test needs controlled multi-axis position or motion
The platform becomes a defined motion source inside the customer’s test architecture.
- A DUT needs controlled position and orientation changes in three or six axes.
- A recorded trajectory, scripted profile or real-time host signal must be reproduced.
- A sensor, controller, component or assembly must operate while it is moving.
- The project needs a custom payload, fixture interface, workspace or host connection.
- Platform response can be validated within an agreed load, motion and duty condition.
A different or additional system may be required when
The primary requirement is force, shock or high-frequency vibration
Some test methods require specialist equipment beyond a position-controlled electric motion platform.
- High-frequency vibration or NVH exceeds the validated platform bandwidth.
- Force-controlled structural fatigue is the main test method.
- Shock, impact, pyroshock or certified seismic testing is required.
- An accredited laboratory or standard-specific test certification is required.
- Hydraulic loading, an environmental chamber or full durability analysis is the main system scope.·

From Recorded or Model Data to a Repeatable Test
The workflow starts with the result the test must produce. The platform command, physical motion and independent measurement need separate definitions so each team knows what has been controlled and what has been verified.
01 · Customer
Test Objective
Define the DUT behavior, output and pass or fail owner.
02 · Input
Source Data
Recorded file, scripted profile or real-time model output.
03 · Shared
Profile Conditioning
Coordinates, units, scaling, filtering, limits and timing.
04 · CSCMotion
Motion Controller
Command validation, kinematics and platform-side safety logic.
05 · CSCMotion
Motion Platform
Executes the approved three-axis or six-axis motion.
06 · Test rig
Fixture & DUT
Receives the physical input under the agreed load case.
07 · Test owner
Measurement
Independent sensors and DAQ support result evaluation.
Controller feedback
Independent measurement
Optional closed loop
Know What the Platform Must Prove
A useful acceptance plan connects the approved load case and trajectory to a measurement point, instrument, calculation method and tolerance. Platform-level validation supports the customer’s test program; it does not certify the complete test system.
01 · Baseline
Freeze the load case
Confirm the representative DUT or dummy load, fixture, center of gravity, profile, interface, duty condition and acceptance criteria.
02 · Configuration
Record what is being tested
Identify the platform configuration, controller version, moving assembly, coordinate system, reference point and applicable limits.
03 · Safety states
Verify limits and fault behavior
Check homing, enabled states, software limits, E-stop, communication loss, faults and the approved recovery sequence.
04 · Representative motion
Run the agreed trajectory
Execute the representative single- and combined-axis profiles under the specified load and duty condition.
05 · Measurement
Compare command and response
Record the measurement location, instrument, sample rate, filtering, repetitions and calculation used for the result.
06 · Closeout
Issue evidence and deviations
Document results, interface checks, duty runs, deviations, open items and the agreed platform-level sign-off status.·
| Evidence source | What it can support | What it does not automatically prove |
|---|---|---|
| Commanded profile | The physical input requested by the file, host or HIL model after agreed mapping, conditioning and limits. | That the platform or every point on the DUT reproduced the command within the required tolerance. |
| Controller feedback | Platform-side actuator or pose feedback, controller states, limits, tracking behavior and fault logs. | Independent motion at the DUT reference point, external measurement uncertainty or complete-system compliance. |
| Independent measurement | Motion at a defined point under a defined load, profile, instrument, sample rate and calculation method. | Universal performance for every load, fixture, axis, frequency, trajectory or operating condition. |
Define the Test by Its Engineering Job
Industry names alone do not specify a platform. These application paths describe the physical input the platform must create and the information needed to review it.
Functional testing
Component and Assembly Testing
Operate a component or loaded assembly while the platform reproduces defined position, orientation or motion sequences.
Sensor & control hardware
Sensor, IMU and Control-Device Testing
Apply repeatable physical motion to hardware with inertial sensing, orientation estimation, stabilization or embedded control logic.
Record & replay
Recorded Motion Profile Reproduction
Convert field or model data into an approved platform trajectory and repeat it under controlled laboratory conditions.
Real-time integration
HIL and Closed-Loop System Validation
Use a real-time host to command physical platform motion while DUT outputs are returned to the model or recorded by the test system.
Equipment under motion
Equipment Functional Testing
Operate a heavy, tall, offset or non-standard assembly while the platform supplies the approved motion input.
OEM test equipment
Custom Test-Rig Integration
Use the platform as the controlled motion subsystem inside an integrator-owned test machine or laboratory architecture.

Select 3DOF or 6DOF from the Required Motion
The correct axis count comes from the test objective and source data. Extra axes add no value if the test cannot command, measure or use them.
| Decision factor | Consider 3DOF | Consider 6DOF |
|---|---|---|
| Required motion | Three defined axes cover the physical input needed by the test. | Six-axis position and orientation or strongly coupled motion is required. |
| Source data | The source has three relevant channels and does not require the omitted axes. | A six-channel record, full pose or real-time six-axis model must be reproduced. |
| Integration | A simpler command, measurement and validation path is preferred. | Coordinate mapping, combined workspace and multi-axis measurement are already defined. |
| Load case | The fixture and CG suit the selected three-axis architecture. | Offset, orientation or trajectory requirements justify a full six-axis review. |
| Product detail | Explore 3DOF platforms → | Explore 6DOF platforms → |
Selection rule: DOF alone does not determine suitability. Payload, CG, inertia, combined workspace, velocity, acceleration, frequency content and duty cycle must be reviewed together.
A motion requirement engineers can evaluate
Motion Profile, Frequency and Duty Cycle
Single-axis maximum values do not describe a multi-axis test. We need a representative combined trajectory and the conditions under which it must run.
Define the coordinate system, units, position or orientation channels, velocity and acceleration, peak and RMS values, frequency content, sample rate, command update rate, scaling, filtering, clipping and cycle schedule.
Single-axis vs combined motion
Peak, RMS and continuous values
Dominant frequency or target band
Representative worst-case profile
Run time, pauses and cycle count
Reset, abort and safe-state behavior
Profile type 01
Scripted trajectory
Approved points or time histories are checked, limited and executed by the platform controller.
Profile type 02
Recorded data replay
Field data is mapped, filtered and scaled to the approved platform workspace and test objective.
Profile type 03
Periodic input
Sine, sweep or repeated cycles are reviewed with load, frequency, amplitude and duty conditions.
Profile type 04
Real-time host command
A test host or HIL model sends commands through a defined data contract and state machine.
Controller, HIL and data integration
Connect the Motion Platform to a Defined Test Interface
Compatibility is confirmed through an interface definition—not assumed from a software name. Commands, states, timing, faults, measurement and ownership must be agreed before integration testing.
Customer / integrator

Questions to close before commissioning
The controller page explains CSCMotion control products in detail. This application page focuses on the data the test requires.
- Who generates and approves the motion profile?
- What command, status, timestamp and fault data is exchanged?
- Which coordinate system, units and update cycle apply?
- What happens after timeout, limit, E-stop, reset or host restart?
- Is DAQ independent, synchronized or part of the HIL loop?
- Who owns the model, DUT I/O, sequence and pass/fail logic?

From feasibility to documented acceptance
A Defined Path to Platform Delivery
A custom industrial test platform moves forward only when the physical input, moving assembly, interface and acceptance method are clear enough to engineer. Each stage closes a different source of project risk.
01 Motion & Geometry Review
Review the test objective, DUT, fixture, mass properties, motion file, dynamics, duty and expected evidence.
02 Engineering Proposal
Define the recommended DOF, geometry, load case, motion envelope, controller, supply boundary and assumptions.
03 Design & Interface Review
Freeze mounting, coordinates, command data, states, safety interfaces, measurement points and acceptance criteria.
04 Build & Integration
Manufacture, assemble, wire, configure and verify the contracted motion-platform subsystem and interfaces.
05 Loaded FAT & Handover
Run the agreed inspections, states, representative load, trajectories, duty cases and documentation closeout.
Scope control: any change to the DUT, fixture, center of gravity, trajectory, interface, duty cycle or acceptance method after specification approval may require a renewed feasibility review.
Industrial Testing Project Evidence
Use approved media that connects the test objective, platform configuration and validation method. A moving platform without the DUT, fixture or measurement context is weak evidence for this page.

Answers from our engineering team
Industrial Testing Motion Platform FAQ
These answers describe our normal engineering approach. The approved technical specification and written proposal define the actual platform capability and supply scope.
What does CSCMotion supply for a professional simulator project?
Our normal scope is the engineered motion-platform subsystem: the mechanical platform, electric actuation, drives, controller, electrical cabinet, agreed platform-side interfaces, documentation and platform-level factory acceptance testing. The exact supply boundary is defined in the project specification.
Does CSCMotion supply a complete flight or driving simulator?
Our standard overseas scope does not include a complete simulator. The simulator OEM or system integrator normally owns the cockpit or vehicle buck, host model, visual and audio systems, training content, instructor functions and complete-system qualification.
Is a Stewart platform the same as a 6DOF motion platform?
Not exactly. Six degrees of freedom describes the available motion. Stewart platform describes a parallel-kinematic architecture commonly used to create six-axis motion. A Stewart mechanism can be configured differently according to load, workspace and geometry. For deeper engineering context, read Stewart Platform Design.
Are CSCMotion motion platforms electrically actuated?
CSCMotion focuses on electric motion platforms. The actuator, drive, power, duty-cycle and thermal configuration are reviewed for each project rather than assumed from a single catalogue rating.
How is motion platform payload capacity determined?
Payload selection uses the complete moving assembly, center of gravity, inertia, offset loads, mounting geometry and required dynamic acceleration. A kilogram value alone is not enough to size the structure and actuators. High-load projects should begin with the High-Payload Motion Platform page.
