您好，请教您Ansys workbench应力仿真问题，谢谢

Question

图及说明发到您的扣扣了，我的扣扣名是ABCXYZ，仿真完软件报告如下：
The deformation is large compared to the model bounding box. Verify boundary conditions or consider turning large deflection on. Refer to Troubleshooting in the Help System for more details.
Contact status has experienced an abrupt change. Check results carefully for possible contact separation.
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.

Answer 1

报告只是警告信息。只是告诉你潜在的，有可能有问题的地方，需要你进行特别关注。
至于分析结果是否正确，需要自己仔细斟酌。

从提示信息看，你的模型应该是包含接触的非线性分析。
提示信息表明2点：
1.结构变形比较大，ANSYS建议你打开大变形开关。

2.结构收敛优点困难，ANSYS workbench自动添加了weak spring以增强收敛。但是人为引入了weak spring，有可能导致不准确的结果,需要仔细检查。本回答被网友采纳
