Application the Finite Element Method to the Design of Mechanical Seals

In this paper, the mechanical seal for some rotatory combustor is designed by taking manifold factors into account. At the first, stress and strain of the seal are theoretically calculated by the finite element method. Then, its structure and dimensions are preliminarily determined. At the last, its structure and dimensions are determined by experiment to make the seal suitable for engineering application. The above method will largely shorten the cycle of developing the seal and save experiment cost. The results indicate that the above method is very effective and practical.
