Abstract

The real contact area of mechanical seal has a great influence on the frictional properties and sealing effectiveness of the interface. Based on fractal theory and the influence of friction, the computer model for the real contact area of dimensionless mechanical seal is established. Based on LabVIEW, a simulation program for calculating the real contact area of mechanical seal is produced. By means of the simulation program, the real contact area of dimensionless mechanical seal-interface payload ratio-interface fractal dimensions-coefficient of scale characteristics curve is obtained. The result shows that the real contact area decreases with the monotonically nonlinear-increasing of interface payload ratio, and decreases rapidly then slowly with the increasing of coefficient of scale characteristics. With the increasing of interface fractal dimensions, the real contact area increases and then decrease, that is there is a fractal dimensions which can make the real contact area reaches a maximum value.
