【Abstract】 Based on the Mont Carlo method and reliability design theory of machine parts, a program is developed on the platform of Visual C++ 6.0, which can be used to analyze the reliability of machine parts by using Mont Carlo method. Comprised of four modules, the program can solve the distribution of random function. It can check and process the user’s input files and transform the relational expressions into corresponding computation model, therefore has good universality. After the user inputs the random variables, the distribution patterns and parameters, and the calculation equations of the stress and strength, the program can make an analysis of the reliability according to the user’s requirement.更多还原
