A Design Approach to Fatigue Reliability

It is usually vital to investigate the implications of fatigue failure during the design of mechanical components. Conventional methods used for analysis during the design of mechanical components are based on the use of Miner’s rule for the estimation of cumulative fatigue damage.

The advent of low cost micro computers suitable for use as an aid to design analysis means that it is now feasible to base the estimation of fatigue reliability during design on procedures involving simulation. It is indicated that the procedures identified represent a potentially general method for the estimation of fatigue reliability from a knowledge of only two distributions of cycles to failure at different loading levels.

The use of the method for the design prediction of fatigue reliability is illustrated with examples and it is shown that the life reliability of particular ball bearing and roller bearing types may be predicted.

The use of the method for the fatigue reliability analysis of a gear drive shaft subjected to combined bending and torsion is also considered with the aid of a numerical example.
