摘要
提出了基于液压油液受压缩建立液压凿岩机工作压力的理论,在此基础上建立数学模型,并以Atlascop1238LE液压凿岩机为研究对象,耦合了蓄能器,建立Amesim仿真平台,对其进行仿真和分析,验证了上述理论的合理性,同时揭示了冲击性能、工作压力与输入流量、活塞质量、活塞油压作用面积、蓄能器充气压力之间的关系,对液压凿岩机的设计具有指导意义。
This article puts forward a theory that the compressed hydraulic oil exerts working pressure of hydraulic drifter,and based on this theory,it established the mathematical model;moreover it took Atlas cop1238LE hydraulic drifter as the research object and coupled to the accumulator to establish a simulation platform of Amesim,which is simulated and analysed to verify the reasonableness of the theory.At the same time,this article revealed the relationship between impact power,impact frequency and working pressure,input flow,the weight and oil pressure area of piston,air pressure of accumulator,which is of essential guiding significance to the design of hydraulic drifter.
