Optimal Design And Experimental Study Of The Optimal Heat Dissipating And Exhausting Performance Of Hydraulic Oil Tank

The hydraulic oil tank is an important auxiliary component of the hydraulic system,which is related that the temperature level and gas content of the hydraulic oil,ensuring the accurate control and normal operation of the hydraulic system.In view of the current high precision and high stability requirements of the hydraulic system,this paper aims at hydraulic assistance.Component—Hydraulic fuel tank,using the combination of finite element analysis and experiment,to study the influence of the internal structure of the hydraulic tank on the oil temperature and gas content.In this paper,SolidWorks is used to establish a simplified three-dimensional flow field model of hydraulic tank.Then,based on the finite element software FLUENT,temperature field and gas content field of hydraulic tank are studied.Experts used a single oil field to study the internal flow field of the hydraulic tank.When the gas-liquid two-phase flow model is used in the finite element simulation,and the group balance model is used to add the calculation equation for the aggregation and fragmentation of bubble particles,that make the finite element analysis of the flow field inside the fuel tank closer to the actual situation.In this paper,The temperature field and the gas content in the hydraulic tank are studied based on two optimization methods: orthogonal test method and uniform design method.When studying the temperature field of the hydraulic oil tank,select six factors that affect the inlet port position,partition height,suction port position,tank design ratio,tank size,and oil absorption rate;carry out orthogonal test studies;when studying the hydraulic tank gas content field,Three influencing factors of the position of the oil inlet,the height of the partition,and the position of the oil inlet were selected to conduct a uniform design study,and the optimization design of the regression equation was fitted.Finally,the experimental method was used to study the temperature and flow field changes of hydraulic fluid entering into the hydraulic system under a certain volume of hydraulic oil tank,different oil absorption positions,different partition heights and different oil return positions,and the experimental results were compared with the finiteelement simulation results Compared to verify the accuracy and reliability of the simulation results,that is scientific theoretical basis for the design of the hydraulic tank.
