Analysis of the Factors influencing Vehicle Handling Stability through Modelling, Equations and Python

Abstract

Car handling stability means that the car can drive according to the given direction of the driver through the steering system and steering wheel when the driver does not feel too nervous or fatigue. Besides,when the car subject to external interference (uneven road, side wind, cargo or passenger partial load), it can resist interference and maintain a stable driving performance. This is very important to ensure driving safety and driving comfort. This paper mainly through the establishment of two degrees of freedom model, sets out a system of equations, solves the analysis of the change of each angle of inclination on the influence of manoeuvring stability, selected vehicle speed, used python to analyze the relationship between vehicle speed and angle of inclination, so as to analyze the relationship between the angle of inclination and the return torque and manoeuvring stability, and try to use ADAMS/CAR to form a whole vehicle dynamics model. Through the analysis of the data and results, it is achievable that the whole vehicle multi-body system could be optimized, so that the vehicle's handling stability can be significantly improved.
