摘要
以QTZ40 0型塔式起重机为例 ,建立其吊臂和平衡臂系统的振动模型 ,分析影响固有频率的因素 ,并详细地阐述了进行振动分析在塔式起重机设计中的必要性。
This paper establishes the FEM model of the steel structural frame of mechanical parking equipment and conduct optimization of the frame′s discrete variables by using Genetic Algorithm.The optimization results show that the weight of the frame can be greatly reduced by adjusting the cross-sectional areas of its components,while satisfying the constraints.
