The Corrected Miner Hypothesis and Its Application in Calculating the Equivalent Load of Machine Elements

A corrected Miner hypothesis has been developed to overcome an obvious defect in Miner hypothesis. The authors, based on this, give out the calculating formulas of the equivalent loads for machine elements which bear different kind of variable loads and put forward some requirements to use it correctly. A practical example of equivalent load is calculated and its result is examined by test. It shows that the formulas are possessed of certain accuracy and may be used in practical engineering.
