标题: 【求助】哪位兄弟给一个轮胎文件和地面文件?就差这个了
我做的例子是北京理工大学出版社  李军的 ADAMs实例教程  
  
他是用的10.0版
  
也可能是版本的问题
作的最后一个例题就是出不来
  
前面是双横臂独立悬架
后面是单横臂
  
就差一个轮胎了
死活不能让汽车跑起来
  
哪位兄弟也是做得这个书?
  
或者做过汽车的整车仿真
麻烦给我2个文件
  
tyre,road 文件吧
  
bow  
  
谢谢

急死了
这个模型一直在做
  
一直没让它跑起来
  
大家帮帮我吧
  
就靠这个毕业呢

我也求助一下,我做的是机器人步行仿真,但是地面我不会做~~~
我只花了个大矩形块,把机器人模型放上面让他走,~~
谁能告诉我怎么出地面啊~~~
上面的那位大哥你给的一大堆英文是什么啊???
俺是菜鸟~~看不懂~~~救命个则啊 ~~

下载下来载入不了啊?还是我人品有问题?
作者: corneringF    时间: 2004-5-30 13:58
我感觉是版本的原因
我们用的是12.0
鬼哥给的估计是2003的
  
不支持
  
要不就是我的人品也有问题...
