摘要
连杆是内燃机的核心部件,其疲劳安全寿命直接影响内燃机的可靠性与安全性。以485Q型连杆为研究对象,采用ANSYS Workbench软件平台的DOE模块,对连杆进行力学分析,并在力学分析的基础上结合Miner线形累积损伤理论对连杆的疲劳安全寿命进行了预测,为连杆疲劳寿命估算提供了一种简单可行的方法,该方法结果精度高,且非常接近于实际工况。
The security and reliability of internal combustion engine is decided by fatigue life of the connecting rod which is the core component. In this paper, DOE model of ANSYS Workbench software is selected as a design environment and fatigue life estimation of 485Q diesel engine connecting rod is calculated by means of finite element combining miner linear cumulative damage. It can be served as a simple and feasible method, the results are high precision and very close to the actual ones.
