| Abstract: |
| The way of non-coupling was introduced to use as a method to simulate the detailed joint model in the conception design. Based on interactional effect among each branch of the detailed joint model, the non-coupling way is described as a principle to make a conceptual joint model. Considered the physical property of the detailed joint model, the non-coupling way could make each branch of the joint model be independent in the angle displacement and be consistent with other in the linear displacement. So the conceptual joint is made of the torsion springs and ball link in this paper. The torsion springs control the angle displacement of the branch of the joint model and the ball link makes each branch be relative in linear displacement. The stiffness of torsion spring could be obtained by solution of stiffness equations which could be got through analyzing the detailed joint model by the FEM software. This method to simulate detailed model has been validated by experiments, and the results have been proved feasible. |
