论文已在中国上海举行的2013年CIMAC大会上发表。论文的版权归CIMAC所有。In this paper, the uniform pressure method, the contact model method and the temperature method are used to simulate the shrink fit of the valve seat ring. Based on theories and calculation results, it is concluded that the contact model method can reflect the real contact condition. In order to investigate the influence of the valve seat ring on the fire deck stresses, the contact model is used. The mechanical stress,thermal stress and thermomechanical stress are calculated. With the valve seat ring, the mechanical stresses increase while the thermal stresses and thermomechanical stresses decrease in the valve bridge areas. Therefore, the influence of the valve seat ring can not be ignored when calculating the stresses of the cylinder head.
