Column-Type Wheel Coupling Road Simulation Test System

The use of column-type wheel coupling road simulation test benches for performance, durability, and reliability tests worldwide is currently the most popular road simulation test technology. It is also one of the most effective methods for the initial reliability verification of the current automotive product development. The test bench is equipped with a set of dynamic hydraulic exciters capable of vertical excitation under each wheel. Through the precise control of each vibration exciter, the road environment during the driving process of the car is simulated. During the test, multiple simulation iterations can be performed according to the collected road load spectrum, so as to carry out vehicle road simulation tests and fatigue durability test items. The VSR column type tire-coupled road simulator applies vertical load to the wheels of the vehicle to perform equivalent force control almost identical to the original road conditions in the test room to perform vehicle noise, durability, component and fatigue tests and many more. The equipment has outstanding accuracy and repeatability, which is convenient for vehicle developers to conduct in-depth research on the characteristics of the vehicle during the vehicle development process.

  • Compared with the actual road test on the test site, the VSR road simulation test system has the following advantages:

    •Speed up the test process, save time and cost, and shorten the vehicle development cycle
    To
    •The test is not restricted by external conditions, such as road conditions, weather, climate, driving operations and other factors
    To
    •The test can be carried out continuously without interruption, and the test intensity can be changed by itself
    To
    •More evaluation parameters can be obtained than actual roads
    To
    •The condition of the whole vehicle can be observed at close range, and the problem can be found in time
    •The improvement plan can be quickly verified, and the development efficiency is doubled
    To
    •Infinitely repeatable, modified, dynamic load, test repeatability is good, strong contrast
