The noemal frame is composed of two stringers and several beams and it is supported on wheels by suspension system, front axle and rear axle. The frame must have enough stiffness and strength to withstand the loads and shocks coming from the wheels, so the stiffness and strength of the frame play a very important role in the designing of the full vehicle. Consequently, the quality of the frame have ralation to the success of the design. In order to avoid the drawbacks of traditional mechanical calculation, this paper adopted the finite element analysis technique to shorten the work cycle and improve efficiency.This paper complete the modeling and the analysis of a light truck frame using CATIA and ANSYS software. Key words: Light truck chassis, Three-dimensional modeling, Loading, Finite element static analysis  目 录 TOC \o 1-3 \h \u  HYPERLINK \l _Toc16088 摘 要  PAGEREF _Toc16088 I  HYPERLINK \l _Toc28063 ABSTRACT  PAGEREF _Toc28063 II  HYPERLINK \l _Toc29979 前 言  PAGEREF _Toc29979 1  HYPERLINK \l _Toc141 1轻型货车车架设计  PAGEREF _Toc141 3  HYPERLINK \l _Toc3961 1.1车架的设计要求  PAGEREF _Toc3961 3  HYPERLINK \l _Toc12893 1.2车架的结构形式  PAGEREF _Toc12893 3  HYPERLINK \l _Toc28773 1.3横梁、纵梁及其联接  PAGEREF _Toc28773 6  HYPERLINK \l _Toc16676 2车架的结构设计  PAGEREF _Toc16676 7  HYPERLINK \l _Toc29073 2.1车架长度及材料的选取  PAGEREF _Toc29073 7  HYPERLINK \l _Toc28348 2.2纵梁截面尺寸的确定  PAGEREF _Toc28348 7  HYPERLINK \l _Toc10396 2.3纵梁的强度计算  PAGEREF _Toc10396 9  HYPERLINK \l _Toc4293 2.4纵梁的刚度条件  PAGEREF _Toc4293 11  HYPE
