摘要
设计了一种后悬臂式立体车库,以该车库的载车板为主要研究对象,利用Ansys软件对其进行受力分析,应用多目标优化设计的方法对边梁的结构尺寸进行优化,确定了优化后边梁的结构尺寸。通过优化分析,提高了载车板的性能指标。优化模型与原模型相比,最大等效应力下降了67.02%,最大变形减少了35.57%,优化效果明显。计算结果表明,该优化设计方法有效,其计算结果为载车板的进一步的设计提供了理论依据。
A post cantilever-beam type stereo garage is designed,which is taken as a main study object for stress analysis in Ansys. The structural size of boundary beam is optimized using multi-objective optimization design,to determine the optimized structure size of the boundary beam. Through optimal analysis,performance indicator of the carrier board is improved. Compared to the original model,the maximum equivalent stress of the optimized model drops by 67. 02%,and maximum deformation reduces by 35. 57%,indicating significant optimized effects. The calculation result shows that the optimal design method is effective,providing theoretic basis for further design of the carrier board.
