Research Of Intensity Contrast Between Different Testing Roads Based On Psd Analysis And Fatigue Damage Cumulation Theory
INTERNATIONAL CONFERENCE ON COMPUTER, MECHATRONICS AND ELECTRONIC ENGINEERING (CMEE 2016)(2016)
摘要
Use the same acceleration collector to get the loading spectrums of two typical different testing roads by the same truck, and then make a contrast analysis of the distributing character by PSD analysis. Extrapolate the two spectrums into the same testing mileage, then make the fatigue analysis of them by the LMS software base on Miner fatigue damage cumulation theory, form the result we can get the equivalent coefficient of two different testing roads. So we get a key method to have regulations and evaluations in road testing.
