摘　　要：针对液压系统中存在的一种气泡发光现象,本文研究了液压油的温度发光现象的影响。本文以液压锥阀的节流阀口为研究对象,采用仿真分析及试验的方法,探究液压油温度在0℃~60℃内变化时,观察其对液压油发光的影响程度。结果表明:在相同压力下,当温度在0℃左右时不发光也无气泡生成,伴随着液压油温度的升高,液压油的发光现象越加明显,当温度达到40℃以后,发光现象趋于稳定。通过本文的研究,进一步明确了温度对液压油发光的影响,为液压气穴研究提供理论和试验基础。A bubble glowing phenomenon exists in the hydraulic system.This study investigates the influence of the hydraulic oil temperature on the luminous phenomena.With the orifice of the hydraulic throttle valve as the research object,simulation analysis and experiment were performed to explore the influence degree of hydraulic oil luminescence when the hydraulic oil temperature varies in the range of 0℃~60℃.When the temperature was about 0℃,there was no luminescence nor bubble formation.Under constant pressure,with the increase in the hydraulic oil temperature,the luminescence phenomenon of hydraulic oil became more evident.When the temperature reached 40℃,the luminescence phenomenon tended to be stable.
