Optimization Design and Virtual Prototype Modeling and Simulation Analysis of FSAE Car Steering Trapezium

Abstract

Based on the overall basic parameters and design requirements of FSAE racing car, a method for optimizing the design of FSAE racing steering system was proposed. Firstly, the mathematical model of the steering trapezium of the steering system was established, and the plane steering trapezoidal parameters were optimized by MATLAB programming. Then the virtual prototype model of steering, forking arm and front suspension was established by using ADMAS dynamic simulation analysis software. The relation schema of the inner wheel and outer wheel rotation angle, the parallel wheel travel and the varying parameters of the up-and-down travel were analyzed to ensure the stability of the racing car in the steering process and reduce the wear of the tire. The results showed that the optimized steering trapezoidal mechanism attained the expected goal and offered reference for the steering system design of FSAE racing car.
