Structural Design and Anti-roll Performance Verification of Mounted Suspension

Vehicle rollover is a common traffic safety accident, in which the dynamic performance of the suspension directly affects the vehicle's handling stability and roll safety performance during cornering. To address the issue of vehicle rollovers when subjected to lateral forces, a dual wishbone suspension based on the mounting concept is designed. Meanwhile, it can help vehicle produce the opposite roll angle to conventional suspensions when subjected to lateral forces, thus achieving effect of preventing rollover accidents. Firstly, the dynamic mathematical model of the proposed suspension is established. Parameters are imported into MATLAB and simulated using Adams to compare the dynamic characteristics of this new suspension with traditional ones. The simulation results show that the dynamic performance of the suspension under different working conditions is significantly better than that of conventional suspension. Finally, real vehicle experiments verify the unique effect of the suspension on anti-rollover, and shows superior anti-rollover performance compared to traditional suspensions, confirming that our proposed suspension structure can improve vehicle handling stability and safety. This concept can serve as a reference for the suspension structure design of mobile machinery such as racing cars and all terrain mobile robots. © 2024 Chinese Mechanical Engineering Society.
