摘 要
立体车库是专门实现各种车辆的自动停放及科学寄存的仓储设施。随着城市汽车保有量的不断增加，停车难问题己经成为大中型城市的一个普遍现象。机械式立体停车库可充分利用上地资源，发挥空间优势，最大限度地停放车辆，成为解决城市静态交通问题的重要途径。本课题以较为典型的升降横移式立体车库为研究对象，综合考虑立体车库制造成本和运行效率的双重因素，对车库的钢结构及控制策略进行了分析优化。
本文在对国内外车库现状及发展趋势做了充分调研的基础上，选择三层四列式车库结构为研究模型。文章简单介绍了车库的主体结构和特点，对车库的控制系统也作了简单的说明，依据升降横移式立体车库的运行原理，对车库钢结构骨架进行了有限元分析，并通过强度理论进行校核，保证了车库的安全性在有限元分析的基础上，对车库钢结构骨架进行合理优化，使车库钢结构重量减少了14%左右，降低了车库制造成本。
关键词：立体车库 钢结构 结构优化 有限元

Abstract
The three-dimensional garage is the storage which is used for automatic parking and scientific storage of kinds of automobile. As the quantity of urban automobile has increased continuously in nowadays ,the hard-to-park problem has become a common phenomenon mechanical stereo garage can use land resource sufficiently and bring space advantage into play ,and maximize the number of parking cars .It has become an important way for static traffic problem of cites .The issue studies the topic mechanical parking system which named up-down and translation stereo garage ,and regards of the two factors
of
cost
of
manufacture
and
operational
efficiency
synthetically ,and analyses and optimizes the structure and the control strategies of the garage .
On the basis of investigation on current situation and developing trend of garage in domestic an abroad, we choose three-layer and four-formulistic garage structure as the research model .The paper simply introduces main structure and characteristics of garage and also gives a short introduction to its control system .The finite element analysis of steel structure of garage is utilized .In order to the guarantee the security of garage, it is checked according to the strength theory. Based on the finite element analysis, reasonable optimization of steel structure of garage is performed .The weight of steel structure of garage is reduced by 14% or so and the manufacturing cost is reduced.
Keywords: stereo garage steel structure structural optimization finite element
