Abstract

A gasket is known as an important component for mechanical sealing between mating surfaces. In case of the refrigerator, a gasket is generally installed into the edge line of a door to prevent cold air leaking out from the inside of a cabinet. The gasket shape used in a refrigerator is very complicated; it has a few deformable small rooms and wings (upper part) and inserting part (lower part) into the door. By the intricate shape, it takes much time and trouble on analysis by using a full-shape model. To settle down this problem, an effective design way of a gasket is proposed in this work. The inserting part is parametrically designed using FEM without considering the complicate upper part, Through this work, computational time and efforts are much reduced comparing to the full-shape analysis method. And the performance of a newly designed gasket was evaluated qualitatively.
