标题: ADAMS 平顺性仿真 请教 [打印本页] 作者: yunfei781518 时间: 2008-6-19 11:11 标题: ADAMS 平顺性仿真 请教 ADAMS 平顺性仿真:1,模板是不是只要组装几个子件,不用全部装吧;
2,模板装好了做整车仿真不成功,后悬静止,前轮微震;
3,试验数据怎么读取阿,比如X 向的加速度曲线 ,事先要在模型里定义测试点和变量吗?
请教高手指点一下,我是刚刚接触这个,没有多少资料,也不太懂,敬见启敏。作者: yunfei781518 时间: 2008-6-19 11:13
我的仿真错误 ,不知道是不是模板出了问题:
---- ERROR ----
The simulation stopped at time = 8.63063E-02 . ADAMS cannot solve
the equations of motion.
The greatest error in an equation is 1.91213E-03 in the
equation for GFORCE result_fourpost.N300_rear_tires.til_wheel.force .
The greatest change in a variable is 2.54343E-14 in the
variable for PART result_fourpost.N300_Rear_Suspension.ges_axle .
Try the following in this order:
1. Use the MAXIT argument on the EQUILIBRIUM, IC, KINEMATICS,
or INTEGRATOR command to increase the maximum number of
iterations.
2. Temporarily change the value of the PATTERN argument on the
EQUILIBRIUM, IC, KINEMATICS, or INTEGRATOR command to
PATTERN = T.
3. Temporarily increase the value of the ERROR argument on the
EQUILIBRIUM, IC, KINEMATICS, or INTEGRATOR command at
time = 8.63063E-02 .
4. If one or more forces change rapidly or sharply near
time = 8.63063E-02, modify the force or forces.作者: yunfei781518 时间: 2008-6-19 11:21
通过脉冲路谱就这样子;
通过随机路谱仿真直接卡死。作者: adamsirene 时间: 2009-3-14 13:05
3,试验数据怎么读取阿,比如X 向的加速度曲线 ,事先要在模型里定义测试点和变量吗?我是在里面做request或者senior你可以试试
你换个求解器或者把误差放放大试试
