摘　　要：设计了一种液压电梯用新型限速切断阀,通过建立数学模型,利用Matlab中的Simulink仿真软件进行了数值仿真.分析了限速切断阀内部黏性阻尼孔直径、进油口压力以及电梯负载质量大小对其动态性能的影响.在液压电梯实验台架上对限速切断阀进行了实验研究,仿真和实验结果基本吻合.采用EN81-2标准对限速切断阀的动态性能指标进行了考核,结果表明这种新型限速切断阀符合液压电梯的设计要求.A new pipe rupture valve for hydraulic elevator was designed. Mathematical models established for hydraulic elevator system were used in numerical simulations on the Simulink environment of Matlab kits. The effects of different viscous damping diameter, inlet pressure of pipe rupture valve and elevator loads on the hydraulic elevator system's dynamic performance were analyzed. Experimental research was also carried out using hydraulic elevator experiment rig. The numerical simulations accorded with experimental results in general. Dynamic performance indexes were assessed by EN81-2 standard. The results show that the new designed pipe rupture valve meets the designing requirement of the hydraulic elevator.
