Abstract： Aiming at the needs of reliability analysis and life prediction of RV reducers for industrial robot joints，a method of compiling accelerated load spectrum for RV reducers was proposed based on service conditions.On-site collection of industrial robot joint torque-time data and data preprocessing，the Markov chain Monte Carlo methods（MCMC） were applied for time-domain reconstruction and service conditions were synthesized as a typical RV reducer reconstruction of the load history. The rainfall counting methods were used for statistical counting，distribution fiting and parameter estimation，to obtain the statistical distribution laws of the mean-amplitude of the load. The mean-amplitude two-dimensional load spectrum obtained by frequency extrapolation were transformed into 8-level one-dimensional program loading spectrum，and accelerated based on the actual applications of RV reducers，which was compiled into a one-dimensional accelerated program loading spectrum of RV reducers，which greatly shortened the fatigue life test cycle.
