        Solution and analysis of VL combined seal lubrication model under the effect of wear

        Yi Zhang,Siyang Xiong,Sipeng Zhong,Zijie Xiong,Qiang Yang 대한기계학회 2022 JOURNAL OF MECHANICAL SCIENCE AND TECHNOLOGY Vol.36 No.11

        Through the finite element calculation of VL combined seal models under different wear conditions, contact pressure distributions of models are obtained. Considering the coupling effect between seal deformation and lubricating oil film, a mathematical model of elastohydrodynamic lubrication for VL combined seal is established. Based on the theory of small deformation, the elastic deformation of VL composite seal under high pressure is obtained by the deformation influence coefficient matrix method. Considering the influence of sealing surface wear and surface roughness, the oil film thickness distribution and oil film pressure distribution of VL combined seal are solved by the finite difference method. The analysis results show the wear of VL combined seal, the decrease of viscosity, the increase of roughness and rotational speed can raise the thickness and pressure of lubricating oil film. The correctness of numerical simulation is verified by experimentally measuring the friction torque and leakage rate of seal.
