车辆多体动力学仿真中的路面模型构造方法的研究

Study on the Building Approach of the Road Model in Multi-body Dynamics Simulation

讨论多体动力学仿真软件中车辆试验路面的生成原理及3种具体的三维路面模型的构造方法 .介绍双轨路形计的工作原理,并用其测量了某试验场路面的不平度数据.依据此数据分别利用3种路面模型构造方法建立了所测路面的模型,通过对所建路面模型的讨论和比较,总结了各建模方法的优点和不足.

The generating principle of road model and the building approaches to the 3D road model in multi-body dynamics simulation software were proposed in this paper. The operational principle of dualtrack profilometer was introduced, and the roughness data of a proving ground were measured by this profilometer. Using these data, road models were built by several building approaches. By comparison, the advantages and disadvantages of each building approach were summarized.
