Abstract
In recent years, precision motion systems have played an increasingly important role in scientific research and engineering applications. Among them, compliant mechanisms are typical enabling components for precise motion. Establishing models for compliant mechanisms is crucial for their design and analysis. In this paper, stiffness modeling is conducted for four typical compliant mechanisms: single parallelogram compliant mechanisms, mirrored single parallelogram compliant mechanisms, double parallelogram compliant mechanisms, and mirrored double parallelogram compliant mechanisms. To validate the accuracy of the proposed models, three-dimensional models of the compliant mechanisms were constructed using UG software, and finite element analysis (FEA) was performed using ANSYS software. The results demonstrate that the deviation between the theoretical stiffness and simulated stiffness of the four compliant mechanisms is less than or equal to 3.5%. The stiffness models developed for the compliant mechanisms lay a foundation for the design of complex compliant motion systems.
