三维随机路面通用模型建立与仿真（Modeling and Simulation of General 3D Virtual Stochastic Road Model）
三维随机路面 数学模型 行驶平顺性
2009/5/22
为了给虚拟样机仿真分析提供复杂三维路面环境，基于单点FFT路面不平度时域模型，建立了三维FFT随机路面数学模型，并实现了其在Matlab中的仿真；依据三角网格法理论，建立了生成三维路面文件的通用模型，包括节点的生成和单元生成算法，并导入Adams形成所需的三维路面仿真环境。应用上述方法生成C级路面，对所选择的车辆样机进行了行驶平顺性仿真，与GB/T 13441—92标准对比分析得到了该车行驶平顺舒...
