ANSYS中的受力分析不能分析出结果是怎么回事,显示的是下面的警告。

At least one body has been found to have only 1 element in at least 2 directions along with reduced integration. This situation can lead to invalid results or solver pivot errors. Consider changing to full integration element control or meshing with more elements. Refer to Troubleshooting in the Help System for more details.

One or more bodies may be underconstrained and experiencing rigid body motion. Weak springs have been added to attain a solution. Refer to Troubleshooting in the Help System for more details. Project>Model>Static Structural>Solution Sunday, March 13, 2016 3:32:51 PM
我的ANSYS总是受力分析不能分析出结果,是怎么回事啊,哪位大神来解答一下,谢谢啦 展开

这是由于在同一实体上,即有绑定接触(MPC)的定义,又有刚性区或远场载荷(MPC)的定义,操作中注意在定义刚性区或远场载荷时避免选择不必要的DOF自由度,以消除过约束。
这一Warning常发生在边界约束条件与约束方程相互交叠的节点位置。解决方法是不选边界约束位置节点,或不选约束方程位置节点。第一个warning发生当节点位置对称边界条件与约束方程向冲突时。第二个warning发生当节点位置约束条件与约束方程相冲突时。

注意事项:
1、只分析根据性质命名的力,不用分析根据效果命名的力,如动力、阻力、下滑力等。
2、注意运动状态,物体的受力情况会随运动状态的改变而改变,必要时要根据学过的知识通过计算确定。比如物块先做匀加速直线运动,然后做匀速直线运动,这两段的受力情况是不一样的。
3、合力和分力不能同时作为物体所受的力,分析的时候要注意只分析实际存在的力,不分析合力或分力。
4、静摩擦力产生的条件中相对运动的趋势要由研究对象受到的某些他力来确定。
