摘　　要：石油钻机井架的起升是井架的危险工况之一,而利用准静态的计算分析方法忽略了绞车转速对此动态过程的影响。采用虚拟样机技术对JJ450/45—K型井架的安装起升过程进行了动力学仿真分析,论述了绞车转速对起升过程的影响。结果表明井架的起升速度与绞车转速之间存在非线性关系。绞车转速越高,起升时的振动越大。Derrick raising is one of dangerous conditions.for drilling rig, the impact of hoisting rotate velocity on derrick raising process is neglected by computational analysis method of quasi static. It dynamic simulation on raising process of K type derrick of JJ450/45 is studied, based on virtual prototyping technology,the effect of hoisting rotate speed on raising process is discussed.The results show that the nonlinear realationship is existed between them.The higher rotate speed of hoisting, the larger vibration in the raising process.
