Abstract：The stiffness of a multi-link hinge is a critical factor influencing its performance.Simplify the entity multi-link hinge into rods,and then optimize its motion trajectory using a multi parameter objective function based on the motion relationship between the rods.Design the entity multi-link hinge according to the optimized optimal trajectory.Then,using structural dimension optimization software,the dimensions of the entity components of the multi-link were optimized,thereby enhancing the overall stiffness of the multi-link hinge.Through analysis of the motion trajectory and structural dimensions of multi-link hinges,the influence of various factors on their stiffness and the optimal structural form were obtained,providing theoretical guidance for the practical application of multi-link hinges to a certain extent.
