Reliability Analysis Method for Type-HY360J Articulated Body under Time-Dependent Uncertainty

A time-dependent model based on stochastic differential equation is presented, which provides a coherent framework for calculating time-dependent reliability. This paper obtained the method of calculating time-dependent reliability which taken uncertain factors into account. It also applied this method to reliability analysis on type-HY360J articulated body. Compared with the traditional method, the reliability of all time horizons of articulated body can be gained by using this method. This paper shows that: by using this method, the reliability of all time horizons can be gained to predict the uncertain evolution and movement or trend of machine reliability. This research can also provide a basis for maintenance of machine.
