In addition to the methods discussed here, you can use the internal multipoint constraint (MPC) feature of certain contact elements (CONTA171, CONTA172, CONTA173, CONTA174, and CONTA175) to model contact assemblies and kinematic constraints. By this method, the program builds MPC equations internally based on the contact kinematics. See Chapter 7: "Multipoint Constraints and Assemblies" in the ANSYS Contact Technology Guide for more information on how to use this feature.
看来mpc和约束方程效果是一样的哦,都可以。 |
