悬架KC分析时出错求好心人解答

首先检查模板的拓扑关系是否出错，再检查通讯器是否完全对应匹配，再看弹簧刚度、预载、簧下质量以及衬套刚度，是否合理，再做下静平平衡验证下，以上都没问题的话，就用排除法，先移除转向子系统，稳定杆子系统，以及关闭驱动轴组件，仿一下，若还是错就可以锁定悬架模板有问题，若没有报错，就激活驱动轴组件再仿一下看是否出错，就这样一步一步验证是最有效的

你调为c特性就不报错，两边两个轮子平行了，无法计算侧倾中心。把摆臂做为柔性体可以解决

---- START: WARNING ----
The Reconcile Acceleration-Force has detected a singular Jacobian matrix.
This problem may be caused by:
(a) A constraint equations that became almost redundant, e.g., the model
is at a singular configuration or at a bifurcation point.
(b) A massless PARTS in the model.
The Sparse Solver has detected a zero pivot for row 68 (during the symbolic pivot selection).
The corresponding equation is: Part/26 Y Force
A minimization algorithm will be used to find a solution on the
projected constraint manifold.
