Investigation of Mechanical Stresses for Cylinder Head of High Power Diesel Engine

摘要

Aim To investigate the influence on the cylinder head's stress distribution and value caused by its structure's changes. Methods Three types of cylinder heads of high power diesel engines were analysed with futile element method using I-DEAS Master series software. The actual condition of the cylinder head was simulated with different kinds of elements. Tempera- ture method was used to exert the predeformation of the bolts to the finite element model, so the pretightening force was discribed accurately. Results Stress distribution regularities of the cylinder head under different working conditions were taken.
