摘　　要：游车大钩是石油钻机提升系统的重要组成部分,实际工作情况下受到的循环动载荷作用以及自身在工作过程产生的振动都会影响整个提升系统的性能。该文基于动力学理论,以ZJ40/2250L-1配套的YG225游车大钩为研究对象进行振动特性分析。通过模态分析和谐响应分析,得出前15阶固有频率、振型及最大应力的位移时间历程结果曲线,为游车大钩的动态设计提供有益的分析数据。The traveling block hook is an important part of the oil rig hoisting system,which is subjected to the cyclic dynamic load in the actual working conditions,and the vibration generated during the operating process will affect the performance of the entire hoisting system.Based on the dynamics theory,the traveling block hook YG225 of ZJ40/2250L-1 is regarded as the study subjects of vibration analysis in this paper.Through the modal analysis and harmonic response analysis,the displacement time course resulting curve of the first 15 natural frequencies,mode of vibration and the maximum stress is obtained,which provides a useful analysis data for the dynamic design of traveling block hook.
