First, the theoretical knowledge of kinematics and dynamics based on the movement of connecting rod and the force in motion a detailed analysis of such issues and get accurate results, while the materials were used on the rod comparison and analysis. Followed by on the connecting rod, connecting rod shaft and the connecting rod small end and size of stru- ctural design calculations, and were checking the structural strength and stiffness. Again, application CAD software: Pro / E software to establish a link of three-dimensional geome- tric model, based on the work in this, but also on the static on the link under the two special conditions; tension, compression conditions were the force calculation, and then link into ANSYS three-dimensional geometric model is defined in its properties, meshing, impose constraints and loads, and finally calculated to achieve the purpose of checking the strength rod Key words: Diesel engine；Connecting rod；Strength check；Pro/E；ANSYS  目 录 摘要 Ⅰ Abstract Ⅱ 第1章 绪 论 1 1.1 选题的目的和意义 1 1.2 国内外的研究现状 2 1.3设计研究的主要内容 4 第2章 连杆的结构设计与分析 5 2.1 连杆的运动和受力分析 5 2.2 连杆的结构分析 5 2.3 连杆的工作条件和设计要点 6 2.4 连杆的材料性能及
