摘要:
为了优化环井式地下立体车库钢结构，进而达到减轻车库架自重，降低生产成本的目的。通过有限元软件ANSYS Workbench，完成对立体车库架处在对称满载条件下的有限元静力分析。并根据有限元分析的结果，应用多目标优化设计的方法来对车库架尺寸和结构进行优化，确定了优化后钢梁的尺寸，完成了车库架应力集中处的结构改进。优化结果表明，与结构改进之前模型相比，优化后车库架的最大等效应力减小了52.71%；最大变形降低了13.74%，与初始模型相比，优化后车库架H型钢材的使用量减少了52.7%。最后，为避免立体车库架在工作时出现共振现象，对其进行无预应力模态分析。
Abstract:
In order to optimize the ring-well underground stereo garage steel structure, and thus realize the purpose of lightening the self-weight of the garage and reducing the cost of the garage, the finite element static force analysis of the garage under the symmetric full-load condition was conducted by the ANSYS Workbench finite element analysis software. According to the results of statics analysis, the size and structure of the garage frame were optimized by using the method of multi-objective optimization design ，to determine the optimized size of the steel beam and complete the structural improvement of the stress concentration of the garage frame. The optimization results show that, compared to the pre-improved structure, after optimization, the maximum equivalent stress of the garage frame was reduced by 52.71%, and the maximum deformation was dropped by 13.74%, and the usage of H-type steel in the optimized garage frame was decreased by 52.7% compared to the original model. Finally, the none pre-stress modal analysis of the stereo garage frame was carried out for avoiding resonance when it works.
