【Abstract】 The paper introduced source and definition of errors in precision centrifuge testing of linear accelerometers. It analyzed effect for accuracy of indicated acceleration in accelerometers test by each error source from precision centrifuge in detail, and introduced calculating method of errors. In precision centrifuge testing of linear accelerometers,the error term could compensated or ignored to improve test precision and reduce difficulty of practice according analyse source and effect of each error term. For the error term to be included, specific numerical values could be calculated.Therefore, the influence of the precision centrifuge equipment on the uncertainty of the whole test practice was determined.By studying the precision centrifuge error model, the way to improve the precision of precision centrifuge’s acceleration input was found. At last,an engineering method for precision evaluation of precision centrifuge was given.更多还原
