| Abstract: | In this paper, by the means of combination of computational analysis and finite element checking, with a frame main sill design of some heavy truck as a carrier, first calculate the mechanical parameters of the groove cross-section frame main sill by a formula of material mechanics, analyze them and then discuss the influence on the mechanical parameters when there are changes in cross-section of main sill, at last check the designed frame static strength by combining with finite element analysis to make it meet the operating requirements, and accomplish the purpose of light weight design. |
