摘　　要：以卡氏定理为理论基础,对平台框架类型及其截面形状用matlab进行了软件编写工作。通过平台框架设计的参数化、模块化,实现了框架刚度的最优化设计。应用该软件对某型号产品的平台框架类型和截面形状进行了优选搭配,找出了符合整体设计要求的最优化的搭配组合;另外,该软件还可以给出不同参数对刚度和自振频率的影响结果,实现了设计中的特征尺寸、关键尺寸的优化设计。该软件的应用及其结果表明:该软件实现了平台框架设计的参数化、模块化;能够对设计起到优化的作用;并可以一定程度上缩短设计周期。The program for platform frames and sections was written using Matlab software based on the Csdtiglinmo’s law.An optimal frame stiffness was obtained by parameterizing and modularizing the platform frames design.By using this program to select the optimum pairing of platform frames and sections,the optimal pairs meeting the whole design found.In addition,the program could provide the effects of different parameters on stiffness and self-oscillation frequency,and realize the optimized design on characteristic size and key dimension.The application and outcome of this software shows that the program optimizes the design,and reduces the design cycle.

关 键 词：框架截面 参数化 模块化 优化设计
