Design and verification of gasket elements between engine mounted components requires computation and physical tests with respect to wear. Wear is a common problem in engines today and mainly comes from engine vibrations and thermal loading. The vibrations are due to inertial loads as well as reaction forces to gas pressure in the cylinders. Here, a new method to correctly simulate the measured wear rate of an oil pan rubber gasket is described. The engine motion is derived directly from measurements and the resulting simulation process has a high efficacy. Much work exists on investigations of gasket sealings between cylinder head and block, where the thermal loading becomes very important. The method described herein, focuses instead on other types of gaskets on the engine, where the main failure mode is due to sliding wear caused by the engine block and component vibrations.
