The wheel coupling road simulation test bench can reproduce the original road conditions in the laboratory by applying force in the vertical direction of the vehicle tire, which is used in the test of vehicle development and verification stage. The highly controllable and repeatable test mode is not only conducive to improving the consistency of the vehicle, but also provides effective data support for the study of the failure mechanism of parts. The system can complete the durability test of vehicle structure, ride comfort test, abnormal noise test, etc., which is applied to the design optimization stage and off-line quality detection of motorcycles, passenger cars, commercial vehicles, light trucks, heavy industrial vehicles and racing cars. SY70W series wheel coupling road simulation test system integrates our servo hydraulic technology achievements, multi-functional MIMO controller with independent intellectual property rights and mature and reliable application software with appropriate accessories, which can provide high precision and high repeatability test solutions for all vehicles.
