Research of Equivalent Testing Coefficient Between Different Roads Based on Multi-axial Rain-flow Method and Miner Theorem

Abstract

In order to have a measurement of the equivalent testing coefficient between different proving grounds, we use the same data acquisition terminal with same acceleration sensor by the same truck, to get the loading spectrums of two typical different testing roads, and then make a contrast analysis by multi-axial rain-flow counting method in time domain. Extrapolate the two spectrums into the same testing mileage by the LMS software, then make the fatigue damage analysis of them base on Miner theorem, form the result we can get the equivalent testing coefficient of two different roads. Finally we get an efficient method to have regulations and evaluations in road testing.
