Optimization of Spring-Tube Fixture Based on Elasticity

Abstract:

This article aims to optimize the clamp arm's length and the number and shape of the slots of the spring-tube fixture. First it uses the theory of elasticity to create the force deformation model of slot with regular shape, and analysis the deformation of the slot numerically. Then draws the relationship between the elastic deformation and the radius of the bore and the arms length while the force is not change, and comes an ideal shape of the bore through this relationship. It also simulates the deformation of fixture with different number of modified slots through the finite element analysis method, and optimizes the fixture for equal strength further. In summary it comes to meet the requirements of fixture theoretically. Finally through experiments the theory gets verified. From the results of experiments the conclusion can be drawn that the corrected fixture is better than before.
