标题: 请教整车仿真为什么出错？ [打印本页] 作者: tlm332016 时间: 2009-5-16 10:25 标题: 请教整车仿真为什么出错？ 做整车仿真出现下列问题，请高手指点。说明一下：我的后悬架是钢板弹簧非独立悬架，用三段梁理论建的，其它都是用ADAMS自带的模板。做蛇形和单移线仿真都没有问题。但下面两个仿真出错：
1、角脉冲转向仿真
--- WARNING ----
Out-of-range Z value for SPLINE c_imp._cv_spline is used for calculation.
The Z value ( 0.0 ) should be between 1.0 and 2.0.
---- ERROR ----
The system matrix has a zero pivot for column 769, which is associated
with VARIABLE/64 Algb Var. Consequently, the matrix is numerically singular.
2、阶跃转向仿真
---- WARNING ----
Out-of-range Z value for SPLINE o_step._cv_spline is used for calculation.
The Z value ( 0.0 ) should be between 1.0 and 2.0.
---- WARNING ----
An out-of-range X value has been used in the spline calculation.
Extrapolation is required for the SPLINE o_step.TR_Steering.gss_steering_assist.
The X value ( 3.2610 ) should be between -3.0 and 3.0.
---- ERROR ----
The system matrix has a zero pivot for column 769, which is associated
with VARIABLE/64 Algb Var. Consequently, the matrix is numerically singular.作者: yuqiands 时间: 2009-11-25 14:51
