Semi-rigid connection used to model the joint in the conceptual design of car bo dies

摘要

The joint flexibility is an important issue in the conceptual design of car bodies. In the paper,semi-rigid connection is used to represent the compliant behavior of multi-branch flexible joints. The simplified joint model is established based on rigid beams and semi-rigid connection. And we adopt compliance method to solve the parameters of the model. Numerical example proved the accuracy of the model by taking Joint B as an example.
