摘　　要：为了延长掘进机的使用寿命,有必要探究其关键零件的可靠性。在Pro/E、MATLAB、ADAMS、ANSYS协同仿真环境下,应用有限元分析软件ANSYS,通过加载ADAMS输出的载荷文件对掘进机铲板进行静力学分析,并给出应力及应变分布云图,找出其薄弱环节;基于应力分析的结果,应用ANSYS Fatigue Tool模块对铲板进行了疲劳寿命分析,结果表明其满足疲劳强度要求;为类似零件的设计提供了量化的依据,同时降低了新产品的研发成本与时间,具有较高的实用价值。To extend the service life of roadheader,it is necessary to study the reliability of its critical part. Under the environment of co-simulation of Pro/E, MATLAB, ADAMS and ANSYS. ANSYS is used to do statics analysis on shovel of roadheader by loading the load files outputted by MSC. ADAMS, so the distribution of the strain and stress is obtained and the weak position is found. Based on the above analysis results, ANSYS Fatigue tool is used for fatigue a- nalysis on shovel of roadheader. The fatigue strength meets the requirements. It provides quantitative basis for designing the similar parts. At the same time, the research and development cost and time for new product is reduced, and the a- nalysis has the high practical value.
