| 摘 要： | 针对飞机装配制造中大型小曲率部件自动制孔设备中柔性导轨自身的特性开展导轨的优化设计方法的研究.该方法通过对柔性导轨特性的分析,提出以导轨极限弯曲半径为目标、弹性和局部刚性为约束、导轨结构参数为设计变量的设计优化模型.基于子问题近似算法和共轭梯度算法,运用Ansys软件的APDL语言编程实现柔性导轨的优化设计.对优化结果进行仿真验证,仿真结果与优化结果相吻合,证明该优化设计方法对指导柔性导轨的开发具有工程参考价值.

| Abstract: | 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. |
