| Abstract: | The theory of micropolar fluids elastic lubrication was used to investigate the mixed friction in mechanical seal and its mechanical model was established.Taking the compressibility of fluid into consideration,mathematical model of this mixed friction was further established and its solution was performed by using finite difference method,so that the performance parameters of the mechanical seal were obtained,providing a foundation for its optimization design. |
