NUMERICAL ANALYSIS OF VALVE STRUCTURE OF HIGH POWER MARINE ENGINE

Valve as an important part of the gas distribution mechanism, is crucial engine. When engine works, valve subjected to high temperature, impact, frictional wear and corrosion other harsh working conditions, reliable durable has impact on safety reliability In this paper, a model four-stroke marine diesel used research object, intake set exhaust models are established respectively. Heat transfer simulation failure analysis inlet valves different structures materials under operating conditions were carried out using finite element analysis. The results show that manufacturing have effects valves; Changing choosing greater heat deformation, thus affecting overall valves.
