RV减速器服役工况加速载荷谱编制方法
Accelerated Load Spectrum Preparation for RV Reducer Service Conditions
摘要
Abstract
Aiming at the needs of reliability analysis and life prediction of RV reducers for indus-trial 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 pre-processing,the Markov chain Monte Carlo methods(MCMC)were applied for time-domain recon-struction 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 fitting and pa-rameter 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 applica-tions of RV reducers,which was compiled into a one-dimensional accelerated program loading spec-trum of RV reducers,which greatly shortened the fatigue life test cycle.关键词
