| Abstract: | Taking the steel head aluminum skirt composite piston as an example, calculates the distribution laws of its mechanical deformation and stresses under the action of the biggest gas explosive force according to three dimension finite element elastic contact problem. Provides a basis for studying the deformation and stresses distribution of composite piston and for the deformation design. |
