Research on Structural Size Optimization of 3-TPT Parallel Mechanism Based on Stiffness Characteristics
Parallel mechanism is widely used in many fields because of its strong bearing capacity,high stiffness and high accuracy.However,in recent years,the concept of optimal design has been more and more applied to the design of parallel mechanisms.In this paper,the minimum eigenvalue is taken as the objective function to optimize the structural dimension of 3-TPT parallel mechanism.Firstly,the influence of structural dimension on the stiffness performance of parallel mechanism is analyzed from the point of view of the overall structural dimension of parallel mechanism,and then the influence of the size optimization of important parts on the overall stiffness performance of parallel mechanism is examined.The minimum eigenvalue method is used to optimize the parallel mechanism,which improves the stiffness performance of the boundary region,and then improves the overall stiffness performance of the 3-TPT parallel mechanism.
