摘　　要：针对YZY800D压桩机的新型转台结构,结合其实际工况,建立了转台载荷计算模型。选取3种典型工况,分别计算转台所受载荷,选取其中最不利载荷工况对转台进行有限元分析。利用基于神经网络的响应面和多目标遗传优化算法,对转台进行参数优化;在参数优化的基础上,对转台结构进行拓扑优化,有效地降低了转台的总质量,为转台受力计算、有限元分析和优化提供了参考。In the light of new slewing table structure on the YZY800D piling machine,establish slewing table load calculation model in combination with the practical working condition.Select three typical operating conditions,respectively,calculate the load of slewing table based on the three kinds of the working condition,and select the most unfavorable load case for finite element analysis on the slewing table.Make use of the optimization software based on neural network and multi-objective genetic algorithm to optimize the slewing table.On the basis of parameter optimization,the shape of slewing table structure optimized by topology,and effectively reduces the quality of the table.Provide reference for force calculation,finite element analysis and optimization on the slewing table.
