ABSTRACT

In this paper, a complete vehicle model of the Baja racing car is established through Adams/car. Through the establishment of virtual simulation experiments, three typical working conditions of steering wheel step input, steering wheel pulse input and single-line shift are tested respectively; by comparing each of the racing cars State parameters are used to evaluate the handling stability of Baja racing cars with different suspension spring stiffnesses, and then to study the influence of suspension spring stiffness on the handling stability of the car. The test results show that increasing the stiffness of the suspension spring reduces the car's lateral acceleration, yaw rate, and roll angle amplitude, which improves the steering stability of the car. Therefore, it can be considered that a reasonable increase in the stiffness of the suspension spring can improve the steering stability of the car to a certain extent.
