摘要
Abstract
The hydraulic system has the trend of integration and lightweight development.The miniaturization of the hydraulic tank will lead to the oil return impact when the oil is returned to the oil,resulting in the phenomenon of gas rolling inside the oil tank,increasing the content of gas pollutants in the oil,affecting the quality of the oil,and even the oil splashing phenomenon at the gas vent cap of the oil tank,affecting the tightness of the system.According to the working conditions of the fuel tank,the applicable conditions of the simulation model are analyzed,and the finite element simulation model of the AGV car fuel tank is established to analyze the initial condition and the oil movement state inside the fuel tank after the structure improvement.A verification experiment was carried out on the AGV car,and compared with the numerical simulation results,the oil return level was similar,and the simulation model had a good calculation effect.Based on the simulation model,an improved fuel tank structure method was obtained that could reduce the oil return impact of the fuel tank.关键词
