摘要
为解决当前钻井泵设备质量重、噪音大等问题,采用有限元分析与结构拓扑优化的研究理论与方法,以达到减振降重的目的。以3500HP型钻井泵曲轴为研究对象,通过运用Ansys Workbench软件建立曲轴结构有限元分析模型,并对该结构进行模态分析,获得曲轴结构前四阶自由模态与振型结果。引入结构拓扑优化方法,得出拓扑优化单元密度分布云图,针对曲轴结构进行优化改进,并与原始曲轴动态参数对比,结果表明:优化后曲轴结构机械性能有所提高,曲轴质量减少7.55%,轻量化效果显著,可为曲轴结构拓扑优化设计研究提供参考。
In order to solve the problems of heavy drilling and high noise of drilling pump equipment,the research theories and methods of finite element analysis and structural topology optimization are adopted to achieve the purpose of vibration reduction and weight reduction.Taking a certain type of 3500HP drilling pump crankshaft as the research object,the finite element analysis model of crankshaft structure is established by using Ansys Workbench software,and the model analysis of the structure is carried out to obtain the first four-order free mode and mode shape results of the crankshaft structure.The structural topology optimization method is introduced,and the topology optimization unit density distribution cloud map is obtained.The crankshaft structure is optimized and improved,and compared with the original crankshaft dynamic parameters.The results show that the optimized crankshaft structure has improved mechanical performance and the crankshaft mass is reduced by 7.55%.The quantitative effect is significant,which can provide reference for the research of crankshaft structure topology optimization design.
