Research of Equivalent Testing Intensity Between Proving Grounds Based on Rain-Flow Technique and Miner Theorem

Use the LMS data acquisition terminal and the PCB acceleration sensor, get the loading spectrum of two typical proving grounds by the same truck, and then make a contrast analysis of the distributing character by the rain-flow counting technique. At the same time extrapolate the two spectrums into the same testing mileage, then make the fatigue damage analysis of them by the LMS TecWare base on the modified Miner rule, contrast the result we can get the equivalent fatigue damage of the two proving grounds. So we get a key method to have evaluations and regulations in road testing.
