In order to optimize the torque fluctuation of the cross-axis universal joint steering system of a certain vehicle model,By extracting the coordinates of key hard points of the steering system in the CATIA three-dimensional digital model of this vehicle model, a simplified simulation model of the steering system is established by using ADAMS/View software.Under the condition of not changing the installation hard points of the steering system, the phase angle of the transmission shaft that can minimize the torque fluctuation of the steering system is obtained through simulation.The results of subjective evaluation and real vehicle verification show that the optimization result of simulation data is consistent with the theoretical calculation result, ensuring the minimum torque fluctuation of the steering system.
