Laplace model for multi-axial responses in fatigue analysis of a cultivator frame

Karlsson, Johan ; Podgorski, Krzysztof LU and Rychlik, Igor (2014) p.141-150
Abstract
This paper reviews means for fatigue damage rates estimation using Laplace distributed multiaxial loads. The model is suitable for description of stresses containing transients of random amplitudes and locations. Explicit formulas for computing the expected value of rainflow damage index as a function of excess kurtosis are given for correlated loads. A Laplace model is used to describe variability of forces and bending moments measured at some location on a cultivator frame. An example of actual cultivator data is used to illustrate the model and demonstrate the accuracy of damage index prediction.
