Data acquisition by a small portable strain histogram recorder (mini-rainflow corder) and application to fatigue design of car wheels

摘要

A very small strain histogram recorder based on the rainflow method has been developed and applied to strain measurement of car wheels under different road tests.Various strain amplitude histogram data under mountain road.city road and high-way were acquired by the recorder for various types of wheels.The data were evaluated by Miner's rule.The results of the damage evaluation have been used for the improvement of dimension and shape of automotive wheels.
