摘要
针对立体车库结构强度低导致安全事故频发的问题，以某公司生产的经济型立体车库为例，采用CAD／CAE技术对其结构进行静力分析与优化。首先运用SolidWorks建立了立体车库结构三维模型；然后导入ANSYSWorkbench中建立有限元模型，对立体车库钢架结构进行有限元静力分析；最后对立体车库薄弱部件进行响应曲面分析，并根据分析结果优化立体车库零件。研究得到了立体车库工作时整体应力和变形的分布规律，最大应力为153．07MPa，最大变形为10．453mm，满足安全使用要求；优化设计后，在保证车库强度和刚度的情况下节约了2．31％的钢材量，为立体车库结构改进提供了参考依据。
Since accidents frequently occur in stereo garage due to low structural strength,so a economical stereo garage manufactured by a company was taken as an example and a static analysis and optimization of its structure were carried out by using the CAD/CAE technology.First,the threedimensional model of the stereo garage's steel frame was set up in SolidWorks.Then,the finite element model established in ANSYS Workbench was leaded in it to make a finit element analysis on the steel-frame structure of stereo garage.Finally,an optimization of the parts of the stereo garage was completed based on the result of response surface analysis on its weak parts.The distribution laws of overall stress and deformation of the stereo garage during working hours were obtained;its maximum stress is 153.07 MPa and maximum deformation is 10.453 mm,so it meets the requirement of safe use.After the optimization design,2.31% of steel consumption is saved while both the strength and stiffness of garage are guaranteed.The research provides a reference basis for the improvement of stereo garage.
