Design Optimization of the Flex Track for Auto-drilling Machine on Large Surface of Aircraft Assembly

A method of design optimization of the Flex Track for drilling machine on large surface of aircraft assembly is introduced.As the features of the Flex Track are analyzed,an optimization model for the Flex Track is proposed,the maximum stress and deformation value of the weakness points are constrained,the minimum radius conducts as the objective with the geometry dimension as the design variable.Based on the algorithm of Subproblem Approximation and conjugate gradient,an Ansys optimization program is written to get different optimization models.Optimized results of the Flex Track are used to guide the design of the Flex Track,which can improve the speed of design efficiency and shorten the design cycle of the Flex Track system effectively.
