| 摘 要： | 建立了非道路用增压柴油机连杆组件3维有限元分析模型,应用有限元分析技术对非道路用增压柴油机连杆进行了3维非线性有限元分析,并用基于第四强度理论屈服条件,计算了连杆关键部位的疲劳安全系数.结果表明:计算结果与实际结果相吻合,SNH4102Z非道路用增压柴油机连杆满足强度要求;连杆小头与杆身过渡处安全系数较低,是较危险的部位.

| Abstract: | The 3D Finite Element Method (FEM) model of connecting rod assembly for off road turbocharged diesel engine was established. And, nonlinear analysis was made of connecting rod assembly for off road turbocharged diesel engine.Moreover, the fatigue safety coefficient under the fourth strength theory was calculated. The result shows that connecting rod can satisfy the strength requirement, and the fatigue safety coefficient of the transition area between small end and connecting rod body is lower than that of other sites,and thus the transition area is more dangerous than other positions. |
