轮胎添加问题
我是按照李军那本书建模，添加轮胎和地面时出现了问题，在网上找到下面一段话，但是找他说的做了，点确定时，出现了错误，希望哪位好心人指点迷津。“Adams2005版的轮胎和路面的添加最容易出现问题，因为05版的添加界面和2003版有较大差异。首先将轮胎文件mdi_fiala01.tir（注意是.tir，而不是李军书中的.tpf，因为要添加的是fiala轮胎而不是UA轮胎，在安装路径：\MSC.Software\MSC.ADAMS\2005r2\achassis\examples\tir下）和路面文件mdi_2d_flat.rdf（在安装路径：\MSC.Software\MSC.ADAMS\2005r2\achassis\examples\rdf下）拷贝到你的工作目录下。然后在左边工具栏中点选力元“Special Force：Tire”，填入轮胎质量和转动惯量（同李军书），在“Tire Property File”中添加工作目录下轮胎文件的工作路径（注意路径中不能有汉字），然后在Location后输入添加轮胎所在悬架处的Maker点坐标，如（-1335.0, 375.0, 825.0），最后在Road空栏处点击右建，选择“vpg_road/create”进入路面添加界面。
3.路面的添加。在此界面，“Part”选择Ground，“Property File”后添加工作目录中路面文件的路径（路径中不能有汉字），在“Location”中填写（0，0，0）坐标，但若没有修改轮胎文件中的轮胎半径，添加成功后，车轮和路面之间存在一定距离，因此我把此坐标改为（0.0, 85.0, 0.0），具体多少根据个人轮胎半径大小而异。最后Eular Angle为（0.0, 270.0, 0.0），如果改为（0.0，0.0，0.0）就是将路面反转，仿真时小车会掉下来（请在仿真时及时修改）。逐次点击OK后轮胎和路面就建立成功了。”

还请说一下路面名字重名命名的详细步骤，见谅，新手。 请在论坛上查一下我以前发的《ADAMS2005r2-View 创建车辆轮胎路面》，可以参考。
现将其中部分内容-路面创建 用附件上传。供参考。参见附件（6幅截图）。 yqsh 发表于 2013-7-15 18:34 static/image/common/back.gif

非常感谢，这个问题已经解决了 天之澜 发表于 2013-7-15 21:28 static/image/common/back.gif
非常感谢，这个问题已经解决了
既然别人帮你解决了 能否将你的帖子修改一下 把解决的方法告诉大家 ？ 轮胎添加问题，按照网上的做法，一步步来没有问题。我的之所以出现问题，看错误提示，其实是创建地面时，在PART项中“地”的名称与模型里的不同，将模型中的地的名称可以改成“ground”，就没问题了。 天之澜 发表于 2013-7-16 09:11 static/image/common/back.gif
