Performance Optimization of Flexure Hinges using Genetic Algorithm

摘要

The flexure hinge is an important part of micro-displacement table in the precision instruments.To improve the performance of micro-displacement table,the key parameters of its flexure hinges:radius and thickness of hinge and length of connecting rods etc.are studied.Aiming at a commonly used parallel four-bar flexure hinges structure,the parameters of flexure hinge are optimized by using the genetic algorithm under the condition that the frequency of objective function approaches a maximum value.
