汽车平顺性计算程序设计

Program design of automobile ride comfort

文章基于理论力学中的力学理论,建立了以悬架、轮胎为主体的分析平顺性的半车动力学模型。将此动力学模型转换成为易于求解分析的传递函数和状态空间形式的数学模型,并建立一定的道路模型,得到接近真实状态的汽车平顺性响应。在GUI界面下利用Matlab中的相关函数建立所求得的数学模型,实现对平顺性各响应相关量的求解。结果表明:本次程序设计方案是合理的、可行的。

Abstrct: Based on the mechanics theory in theoretical mechanics, this paper establishes a semi-vehicle dynamics model with suspension and tire as the main analysis. This dynamic model is transformed into a mathematical model that is easy to solve the transfer function and state space form of the analysis, and establishes a certain road model to obtain the vehicle ride comfort response close to the real state. In the GUI interface, the obtained mathematical model is established by using the correlation function in Matlab, and the solution of the correlation correlation of the smoothness is realized. The results show that this program design is reasonable and feasible.
