Abstrakt Abstract:

The vibration load subjected to many products is the combination of several random processes corresponding to different application conditions, such as the various field road load inputs for automotive components. Sometimes the input loads are the combination of random and sinusoidal vibration. Due to the convenience of test setup and monitoring, the sinusoidal vibration sweep tests are often used for product durability validation by many automotive and consumer product manufacturers. It is therefore important to correctly correlate the sweep test to the field vibration. This work presents a tool for transferring the measured field random vibrations into a sinusoidal sweep test by using the damage equivalence technique. This requires that fatigue damage generated in the sinusoidal sweep be equivalent to the damage during the desired lifetime in the field operation. Based on this approach, a correlated lab-test specification, including the vibrations level and test duration, can be determined according to the field random load input, the desired product life goal of a product, and the material structural properties.
