Research on Load-Spectrum Construction of Automobile Key Parts Based on Monte Carlo Sampling

CODEN: JTEVAB

Abstract

Load spectrum is a decisive factor that is used to analyze fatigue, reliability, and durability of components. In this article, the typical load spectrum of proving ground is collected through load measurement equipment. Load-spectrum preprocessing, including spikes filter, signal denoising, and low-amplitude load elimination, are completed. According to parts correlation of automotive transmission systems, the load transmission route is established. The Monte Carlo sampling is applied to analyze interference of random factors in the process of load transfer route. Load spectrum of key parts of the automobile is determined and thus rain flow counting analysis is scheduled. A non-parametric method is used to complete load-spectrum extrapolation. Eventually, one-dimensional and two-dimensional programming load spectrums are built. The technical basis for fatigue life prediction and references for other similar researches are provided in this article.
