Brake system, ECAS, Road simulation testing rig

Automobile road simulation test rig

The Automobile road simulation test rig uses electro-hydraulic servo technology and specialized static pressure supported servo actuators. Based on the vibration signals of the vehicle’s wheels during actual road or car testing, indoor random fatigue and vibration tests are conducted on the vehicle to analyze various functional indicators.

This device can perform vehicle reliability and durability enhancement tests, indoor simulation experiments of vehicle smoothness, dynamic performance simulation experiments of vehicle/component, and vehicle NVH testing.
