摘要
本文是“塔式起重机金属结构计算机辅助设计”科研课题其中的一个成果。文中以井型底架结构为例,首先说明了塔式起重机行走式底架结构总成力学模型的建立方法;随后给出了它们优化设计数学模型和计算机程序的N·S图,并应用离散优化技术作了实例计算;最后就行走式底架结构总成设计中有关的问题作了简要说明。
This paper is one of the achievements of the researchitem for computer-aided design of tower crane's steel structure.In thepaper,taking the well-base structure as an example,first the method establishing the mechanical model is explained for the base structure ofa movable tower crane.Then the math model of its optimal design andthe N-S figures for the computer program is described and calculatedusing discrete optimal technology.Finally the problems related to thedesign for the base structure of a movable tower crane are briefly illu-strated.
