摘要
针对钻机液压系统的设计问题,构建了基于AMESim的钻机回转系统仿真模型,完成了普通钻机回转液压系统和钻机负载敏感回转液压系统特性的对比分析,进行了不同工况下钻机回转系统的回转和能耗特性的仿真。仿真结果表明,钻机负载敏感回转液压系统能够更有效地解决回转系统调速困难和发热量大等问题。
According to problems existed in the design of hydraulic system of mine drill, the simulation model of the rotation hydraulic system of mine drill is established based on AMESim. A comparative analysis between the common rotation hydraulic system and the load sensing hydraulic system is completed, and the rotary characteristics and energy consumption of rotation hydraulic system under different working conditions are simulated. The results show that the load sensing hydraulic system of mine drill can solve the difficulty of speed governing and heat relea- sing more effectively in rotation hydraulic systems.
