Research on the Design and Simulation of Jumping Suspension System for Light Off-Road Vehicle

Aiming at the insufficient ability of the light wheeled off-road vehicles on overcoming obstacles or crossing the ditches at high speed, a jumping suspension system design scheme is proposed, the active suspension structure is designed, and the specific jumping processes of off-road vehicles are defined. After that, relevant parameters of active suspension are calculated according to certain vehicle body parameters and obstacle crossing requirements, and a modeling simulation is carried out in Amesim using the calculation results. The feasibility of the design of the jump suspension system is verified.
