摘要
对液压工作介质的存在状态、物理特性和建模机理进行分析,确定研究内容和方法。给出油液黏度、密度、比热容和导热率受压力、温度、空气含量影响的数学模型,对各种模型进行对比和分析,提出使用建议。并展望国内在该领域今后的研究重点。
Based on the analysis of hydraulic mcdium＇s state, physical characteristics and modeling mechanics, the study object and method were defined. The mathematic models of hydraulic oil＇s viscosity, density, specific heat and thermal conductivity influ- enced by pressure, temperature, air content were described. Application suggestions were obtained by compare and analysis of different models. An outlook of the national future research was presented.
