可以自己编的,我编了 jeep_tire.tir 和 jeep_road.rdf , 可在ADAMS 中导入jeep_road.rdf时却出现 "无效METHOD" 的提示, 我也不知怎么回事, 求教各位高手!!! (jeep_road.rdf 是按照李军书上的 , 拿记事本编写的)

楼上的，你的轮胎文件的文件类型是不是错了啊？
jeep_tire.tpf

李军书上轮胎文件的类型是 .tpf , 但我在MSC.ADAMS 2005 中导入轮胎文件时要求的是.tir 文件, 所以我把扩展名改成了.tir . 其实在软件的安装目录(MSC.Software\MSC.ADAMS\2005\solver\atire\roads.tbl)下也有自带的轮胎文件和路面谱文件,我选用了其中的一个,当时效果挺好也没出错, 但可惜最终整车模型出来后,还是没防真成功
