Features

High-performance motion control system based on NI (National Instruments) technology, modular and standardized for flexible configuration and easy after-sales service.

Dual digital closed-loop control for load and displacement, with seamless switching.

Three servo actuators can operate individually or simultaneously, supporting multi-channel parallel measurement, display, and data storage.

Loading time adjustable according to servo speed; load control allows reaching target in as fast as 2 s.

Hold time at target value adjustable from 1 s up to unlimited duration.

Test data can be processed and stored as a complete module; flexible parameter combination allows easy retrieval and analysis.

Comprehensive safety features, including overload protection and software-based safety measures to ensure personnel and equipment protection.

Accessories

Clamping fixtures for seats and seat belts

Data acquisition modules

Optical encoder sensors

Control software license

Safety protective enclosures

Test Procedures

Secure the automotive seat, mounting device, and seat belt system onto the test base.

Configure test parameters in the Windows-based control software, including actuator force, stroke, and loading speed.

Verify safety measures and protective enclosures are in place.

Initiate the test; servo actuators apply controlled load to the seatbelt anchor points and mounting devices.

Monitor real-time data including force, displacement, and velocity.

After the test, retrieve and analyze stored data from the database.

Inspect the tested components for deformation, failure, or performance deviations.

Maintenance Information

Inspect servo actuators and load sensors regularly for wear or calibration drift.

Verify optical encoder displacement sensors and data acquisition system accuracy periodically.

Ensure T-slots and fixtures are clean and free from debris.

Check control software and database integrity before each test cycle.

Maintain a clean and stable environment to prevent external interference with test results.
