摘要
针对纯液压油与空气的混合油液的非线性变化特性，建立了溶解了空气的液压油液密度及油中空气含量随油液压力、温度变化的非线性数学模型；最后应用MATLAB软件对液压油的非线性特性进行了仿真。研究结果为建立精确的液压系统模型并进行动态特性分析奠定了基础。
For the non-linear property of hydraulic fluid when the temperature and the pressure of the hydraulic fluid and the amount of dissolvable air vary in fluid, the mathematical model was built which shows the hydraulic fluid effective density using the pressure, temperature and air content parameters. The simulations of the hydraulic fluid non-linear characteristics were carried on based on MATLAB software.
