- This article elaborates the wheel loader transmission load spectrum during the preparation of the key issues - how to determine the shape of the kernel function, chosing three typical operating conditions to illustrate the non-parametric statistical extrapolation of this process. Before sample loading spectrum is pushed forward, of the signal de-noising of time-domain signal load testing should be completed. Thus, samples of the load cycle and the corresponding kernel function shape is obtained by using rain flow counting method, proposing rain flow matrix non-parametric statistical extrapolation lifetime load spectrum estimation. Because it can achieve a good estimate of the load cycle, it does not appear in the sample load cycle, but may be present in the life course of load. It can be easily seen that the extrapolation is valid and reliable.
