Finite Element and Optimization Design Analysis on the Sword Sley of the New Developed Rapier Loom

The paper introduced the application of finite element method in developing rapier loom. The stress and strain of the sword sley which is a key part of the new developed rapier loom can be obtained By using finite element analysis. The sensitivity analysis is carried out according to the distribution of the stress and strain. The variation of the main parameter can be determined after sensitivity analysis. The optimized result of these parameters can be obtained by optimization study. At last the optimized result fed back to the part design system to complete the design change.
