标题: 扭转梁后悬架 Roll & Vertical Force Analysis 出错 [打印本页] 作者: lyzs727 时间: 2008-11-14 14:36 标题: 扭转梁后悬架 Roll & Vertical Force Analysis 出错 扭转梁后悬架 Roll & Vertical Force Analysis 出错
各位，我现在在做一个扭转梁后悬的k&c仿真，每一种仿真都很好（平行轮跳，反向轮跳，侧向力，纵向力，回正力矩），除了 Roll & Vertical Force 分析，
报错如下：

TVFLEXEFAULT_C
A default *non-zero* damping is used for FLEX_BODY/1 (baocuo_roll_angle.zp11_rear_2005_fbs_Hframe1).
By omitting specifying a damping ratio for FLEX_BODY/1 (baocuo_roll_angle.zp11_rear_2005_fbs_Hframe1)
you have selected default damping characteristics for the body.
The default damping is nonzero, as follows:
1% for modes with natural frequency below 100Hz
10% for modes with natural frequency between 100Hz and 1kHz
100% for modes with natural frequency above 1kHz
where the damping values denote a percentage of critical damping
for a given mode. This may be overridden in one of two ways.
a) by specifying a function expression for CRATIO. To remove
damping altogether, set CRATIO = 0.
b) by specifying CRATIO = USER(...) and supply a DMPSUB
user written subroutine.
