Finite Element Numerical Simulation and Optimization Design of a Specialized Fixture for Drilling Forks
Based on the structural characteristics of drilling holes on the lathe fork,a special drilling fixture was designed,finite element numerical simulation and lightweight optimization design were carried out on the clamp using ANSYS software,and modal analysis verification was carried out on the optimized structure.The results show that the original clamp has relatively small stress and deformation,and there is a large space for structural optimization,the lightweight optimization scheme reduces the specific weight of the clamp by 1.94％while keeping the stress and total deformation basically unchanged,improving the optimization efficiency and achieving the lightweight of drilling specific clamps,the optimized clamp structure is reasonable and does not exhibit resonance,providing a reference basis for the processing,clamping,and mass production of such parts.
