Research on New Numerical Calculation Method for Reliability of Mechanical Strength Based on Blind Number Theory

The uncertainty variable in mechanical design is expressed in blind number and the relation among variables is expressed in the operation rule of blind number; By combining the reliability design theory with blind number calculating method, the reliability of the mechanical elements with arbitrary distribution parameters and discrete test data is discussed; and a numerical method for mechanical reliability based on blind numbers is presented. Besides, the typical examples show that the method is reasonable and effective.
