| 摘 要： | 建立了汽车整车振动系统的八个自由度非线性力学模型，考虑了钢板弹簧和减振器的非线性特性，在四轮相关随机路面激励的条件下，采用分步线性化法对整车振动进行了时域模拟和傅立叶谱分析，并通过试验验证了模拟方法准确性．进而对整个模拟过程进行了Visual C 可视化编程，编写的AVAS软件可实现平顺性的分析、预测和参数优化，可作为汽车平顺性设计的辅助工具．

| Abstract: | A nonlinear dynamic model with 8 DOFs of automobile vibration system, which considering the nonlinear characteristics of leaf spring and shock absorber,is built in this paper. Using the multi-step linearization algorithm, the system experiment data indicates that the proposed simulation method is accurate enough. Furthermore, based on the proposed process, a software named AVAS is developed by Visual C++ language, which can be used as an accessorial tool to accomplish analysis, prediction and parameter optimization of the ride performance in automobile design. |
