摘要

Using the finite element analysis technique, by the method of the parameter study, main key dimensions of the cylinder head of a certain internal-combustion engine are analyzed. Under the mechanical load, the variation rules of the Von-Mises maximum stress on the cylinder head are obtained, which are influenced by the thickness of the floor plate, head plate, jobbing sheet, standing partition board, and side plate of inlet port and exhaust port. It is verified that there is an ideal matching point among those above-mentioned main key parameters. The quantificational proportion relations, between these key structural parameters and Von-Mises maximum stress of cylinder head, can provide a good help for the cylinder head's structural design.
