螺旋槽机械密封摩擦副界面流固耦合分析
Fluid-solid Coupling Analysis of the Friction Pair Interface for Spiral Groove Mechanical Seal
摘要
Abstract
Based on the 3D finite element models of the fluid-film and solid of the friction pair interface for spiral groove me-chanical seal,the fluid-film between the faces of the static and dynamic is simulated ,and the law of the pressure distribution was obtained,the result show that pressure distribution is nonlinear.After that,the pressure was imported into static analysis module as one boundary condition of dynamic ring,then the one-way fluid-solid weak coupling was achieved by automatic iterative of the two steps.,the values indicate that the maximum deformation occurs on the spiral groove in the face of dynamic ring,while the maxi-mum stress occurs on the end of the spiral groove.Further,the effect of the rotational speed of dynamic ring,the pressure differ-ence and the viscosity on the maximum deformation and stress were also studied,the result provide a beneficial reference for the optimization of sealing performance.关键词
