路面时域波形的数学模型与再现研究
Journal Title: Science Paper Online - Year 2009, Vol 4, Issue 10
Abstract
路面不平度作为汽车最为直接的输入,影响到汽车动力学各方面的性能。路面不平度过大,使汽车平顺性和操作稳定性变差,同时道路使用年限变短,造成大量的人力物力浪费。因此,路面时域模型的准确性对汽车动力学性能研究有着重要的作用。介绍路面不平度的表达,引入基于AR建立路面时域波形数学模型的方法,编制运用该模型生成标准路面时域波形的软件,并对GB7031—87中规定的各级路面进行模拟。结果表明,该模型能够很好地描述各种等级路面,能够满足室内再现标准路面波形的需要。
