摘　　要：连杆是内燃机动力构件的重要组成,对连杆结构进行优化,确保性能能够满足运行要求,是内燃机设计优化关注的重点问题。本文在对连杆整体进行优化设计基础上,对结构强度进行校核和疲劳分析,分析结果显示:在承受载荷和约束条件确定情形下,更小结构尺寸的连杆能够满足强度要求。Connecting rod is an important component of the internal combustion engine power components,optimizing the connecting link structure to ensure that the performance can meet the operation requirements is the key of the design optimization of the internal combustion engine.Based on the optimization of the overall design of the link,the structural strength is checked and the fatigue analysis shows that the link with a smaller structural size can meet the strength requirements under the load and constraints.
