Finite Element Analysis of the Sealing Performance of a New L-shaped Seal
By comprehensively considering the influence of rubber material,medium and other factors on the sealing performance of the new seal,finite element simulation analysis of a new L-shaped seal was carried out using ABAQUS soft-ware to obtain the contact pressure distribution at the contact interface.Based on the FFT method,the reconstructed surface morphological features were established as a function of the contact pressure.A raster model was used to search for leakage channels,and hydrodynamic analysis was carried out to solve the leakage rate relying on the parallel flat plate model.The stress-strain and the contact pressure distribution of the sealing rings with different thicknesses under a fluid pressure of 2.6 MPa were studied.The results show that the the volumetric leakage rate tends to increase with the increase of seal thickness and medium pressure,and the contact area of the leakage channel expands gradually.The research result is of guidance for the life prediction and failure analysis of new rubber seals.
