Given the requirements that spacecraft have long life and high reliability, the Remaining Useful Life (RTJL) prediction of a key unit! such as the momentum wheel MW) has become a major area of research. This method aims to solve the problem that how to calculated failure Probability Density Function (PDF) of a unit with work condition switching. Based on the Nelson hypothesis and several failure PDF of constant work condition, failure PDF of a unit which experiences multiple work condition switching during service life has been analytic solved. In addition, takes MW as an example to analyze the common work mode of a unit. Numerical simulations are provided to demonstrate the effectiveness of the proposed method.
