Thermal Mechanism

The paper analyzed the temperature field, the thermal stress field and the stress field under mechanical loads of a diesel engine cylinder head with finite element analysis software ANASYS, then took above temperature field results and mechanical loads as boundary conditions to impose on the established model of cylinder head using the thermal mechanism indirect coupled method, researched the stress field and distortion of cylinder head under effect of multiplicative loads. The result indicates that the point of the highest temperature and the maximum thermal stress locates on the middle nose of fire deck; under thermal mechanism coupled effect, the points of maximum stress locate on the interface of bolt head and screw of cylinder head and on the middle nose of fire deck; the maximum pull stress the cylinder head undertook is less than that the material can survive; the distortion of the cylinder head is very small, thus has little influence on the fabrication of other accessories, and the global distortion of cylinder head performs symmetry.

The nature and mechanism of cracking in cast iron diesel cylinder heads arising from the differential thermal strains which occur in service are reviewed. The results of experimental work with test apparatus simulating the conditions in a cylinder head are presented, illustrating the importance of controlling the boiling conditions of the water at the cooling face of the flame deck. It is concluded that cylinder head temperatures, and therefore the danger of cracking, can be successfully reduced by increasing the flow of cooling water over critical areas by some form of directed flow.
