摘要
本文应用概率统计理论建立了推土机履带链轨节危险点随机应变的均值、幅值二维联合概率密度函数,并编制了二维载荷谱,从而为估计链轨节的疲劳寿命提供了一个前提。
In this paper, the two-dimensional probability density function of the random strain mean value and amplitude value at the dangerous point of the track of bulldozer is proposed by using the theory of probability and statistics, and the two-dimentional spectrum is compilated so that precondition is prepared in order to estimate the fatigue life of the track.
