摘　　要：为了得到不压井修井机井架在起升过程中液压系统的双级液压缸对系统动态性能的影响及井架内力的变化情况,基于AMESim软件的HCD库,采用2个单级液压缸级联方式建立二级液压缸的模型并进行仿真研究。针对不同的起升角度,对不压井修井机井架进行了起升过程的有限元仿真分析及综合分析比较。通过仿真曲线,验证液压系统建立的正确性,并得出多级液压缸在换级时,由于流量发生突变,将产生较大的液压冲击和波动;井架在起升的初始位置受到的应力和位移都最大的结论。可为此类新型修井机的设计及改进提供理论支持。In order to get the dynamic performance of double hydraulic cylinder of the hydraulic system and internal forces of the derrick on derrick lifting process of snubbing workover.Double hydraulic cylinder is used on derrick lifting system of the new workover.Based on the HCD library of AMESim software,two single hydraulic cylinders are used to establish secondary hydraulic cylinder model.For different lifting angle,the finite element simulation of derrick in lifting process is executed.The hoisting results of different lifting angle are synthetically analyzed.The simulation curves verify the validity of the hydraulic system.The conclusion which larger hydraulic shock and fluctuations will happen is obtained due to traffic mutations when multistage hydraulic cylinder change level.And it is concluded that the stress and displacement of derrick in the initial position is the biggest.The theoretical support is provided for design and improve of the new workover.
