Contact with rough surfaces in mechanical seal applications
If the contact is completely under the condition of plastic deformation, the stress of the micro-convex sphere after deformation is equal to the yield stress of the material, which can generally be expressed by the Brinell hardness value of the softer material in the contact material. Assuming that the material only moves down vertically without expanding in the horizontal direction, the load on each asperity of the contact area at this time is a formula.
It can be seen that under the condition of plastic deformation, the actual welding area of u200bu200bthe mechanical seal has a linear relationship with the load. It is the contact condition of smooth surface and rough surface. 348.html,
