Abstract
Using finite element method, influence of diesel cylinder head structure on fatigue strength is investigated. A simplified head model with function characteristics is built for thermal-mechanical simulation. From the simulation results, the influence of valve bridge structure and roof transition fillet dimension on fatigue strength are obtained. And a new valve bridge structure which can effectively improve the fatigue life is proposed.
