| Abstract: | 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. |
