Elastic deformation and contact pressure of mechanical seal:

If a cylinder contacts a plane, its elastic deformation and contact pressure can be calculated according to the Hertz formula. As shown in the pavilion 2-53, it changes from line contact to small area contact under load, and half of the contact surface width (half width) is

Its maximum contact pressure is

where W is the load on unit contact width

The comprehensive elastic modulus E can be calculated as follows:
