摩擦提升机滑动保护装置液压加载系统建模及参数优化研究

针对摩擦提升机滑动保护问题,设计了一种以液压加载系统作为动力源的摩擦提升滑动保护装置,给出了液压加载系统的原理图,并基于AMEsim建立了液压加载系统模型。通过分析得到了不同参数的液压缸、蓄能器和管路等对于液压加载系统性能的影响。结果表明:为提高防滑装置液压加载系统的响应时间,可以增加蓄能器的容积,减小管路的长度,而液压油缸的大小参数应协调活塞杆位移响应速度和输出正压力大小进行优化设计。

Hydraulic Loading System Modeling and Parameter Optimization Study of Sliding Protection Device of Friction Hoist

Aiming at the problem of sliding protection of Friction Hoist, a kind of Friction Hoist Sliding Protection Device with Hydraulic Loading System as power source is designed. The schematic diagram of Hydraulic Loading System was given, and the analysis model was established by AMEsim. The influence of different parameters such as hydraulic cylinder, accumulator and pipeline on the performance of the system was obtained through analysis. The results show that in order to improve the response time of Hydraulic Loading System, the volume of accumulator can be increased and the length of piping can be shortened. While, the size parameter of hydraulic cylinder should coordinate the displacement response speed of piston rod and the output positive pressure for its optimal design.
