Worm Drive Fuzzy Optimization Design And Finite Element Analysis

In this paper,the plane double enveloping worm(PDEW)has been researched,The model of fuzzy optimization design of plane double enveloping worm has been built by fuzzy theory and the methods of mechanical design.Its program has been completed with Visual Basic(6.0).The object functions of fuzzy optimization design were the maximums transmission efficiency and the minimum volume of its construction and their weighted object function of them.The keep with bounds were included the contacting strength and winding strength and deforming strength and the sizes of constructions of PDEW.The keep with bounds were be fuzzy by the method of oblige line.This program not only has been used to optimization the PDEW but also could used to control the fuzzy factor that could change the strength of fuzzy.When the fuzzy factor equal to one,The fuzzy optimization program could change to a general optimization program.This program has been tested and verified by an example.The result indicates that this program is safe and reliable for PDEW fuzzy optimization.Take the example as the foundation, and has established the plane double enveloping worm(PDEW) adjuster, the worm gear three-dimensional model, the meshing model with the Pro-E software.And make the finite element stress analysis to the worm with the software of "Ansys", has confirmed in the PDEW driving design the fuzzy optimized design superiority.Has obtained certain conclusion,but is restricted in other reasons.The research result cannot still apply in the actual project.
