A mathematical model of trench crossing is established for a 4×2 off-road vehicle, which provides a theoretical reference for simulation. Using the ADAMS macro command, the custom interface completes the secondary development design of the vehicle’s trench crossing simulation module. The simulation module has a good human-computer interaction, and can quickly complete the simulation model establishment and results extraction. The simulation results show that the module can simulate the condition of the vehicle trench crossing accurately and obtain the force of the relevant parts of the vehicle, and provide the calculation basis for the vehicle strength and other related design.
