摘　　要：利用MATLAB软件和可靠性理论,给出了对机车关键部件的可靠性分析实用方法。在MATLAB平台上,针对实现可靠性分析的几种实用的方法,编写相应计算程序,通过实例计算,说明文中方法在工程实际中的应用。以某机车的连杆为例,通过几种方法数值模拟结果的对比,进行了可靠性分析,验证了文中方法的正确性和有效性。Using MATLAB software and reliability theory, a practical method for reliability analysis of locomotive key components is given. On the MATLAB platform,aiming at several practical methods of reliability analysis, the corresponding calculation programs are compiled,and the application of the method in the engineering practice is illustrated through example calculation. Taking the connecting rod of a locomotive as an example,a reliability analysis is conducted,and the correctness and effectiveness of the method are verified by the comparison of numerical simulation results of several methods.
