[交流] 【求助】ADAMS/CAR仿真问题已有3人参与

我在car里面建立了一个4WS整车模型，进行角阶跃实验，只能进行40km/h以上的仿真，此速度以下的仿真失败，给的阶跃信号都相同。失败提示如下：

---- ERROR ----
Attempt = 1. No convergence after 25 iterations. Best iteration = 22.
Trying next attempt with a different set of statics parameters...


For the last attempted iteration the equation with the largest error
was VARIABLE ddddddd_step.testrig.vas_brake_demand.variable  Error = 2.64434E+07

The variable receiving the largest increment
was FIELD ddddddd_step.TR_Front_Suspension.bkl_top_mount.field  Delta = 7.55915E+09

---- ERROR ----
Static equilibrium analysis has not been successful.

这是怎么回事啊？同一个模型为什么低速仿真不成功啊？
