摘要

本文研究了利用简化的麦克弗森悬架系统模型对主动悬架系统控制器进行整定的可能性。与传统的线性四分之一车悬架模型相比，采用非线性悬架模型可以获得更精确的响应。在MATLAB/Simulink中对所建立的麦克弗森悬架系统二维非线性数学模型进行了仿真，并与Adams/View多体模型进行了对比验证，分别进行了运动学分析和动力学分析。结果表示为两个模型输出之间的标准化均方根偏差值。两种模型的大部分输出是一致的，最大的区别是在数学模型中通过简化线性化得到的弧度角值。

Validation of a Nonlinear Two-dimensional MacPherson Suspension System Model with Multibody Simulations

This paper studies the possibility to use a simplified MacPherson suspension system model for tuning active suspension system controllers. With a nonlinear suspension model, more accurate responses can be obtained compared to a traditional linear quarter-car suspension system model. The presented nonlinear two-dimensional mathematical model for the MacPherson suspension system is simulated in MATLAB/Simulink and validated by comparing it to an Adams/View multibody model with three simulation cases, one for kinematic analysis and two for dynamic analysis. The results are expressed as normalized RMS deviation values between the outputs of the two models. Most outputs of the two models go hand in hand, and the greatest difference is in the camber angle values derived from simplified linearization in the mathematical model.
