【Abstract】 The theoretical basis of the thermal analysis of piston is discussed and a 3-dimensional finite element model is built up.The thermal field of the piston is calculated,and the 3-dimensional thermal field distribution characteristic is got,therefore,it supports the further improvement of piston.更多还原
