Compensation of synchronization error effect in testing machine calibrationHiti, Miha (Avtor) force calibrationloading profilemeasurement uncertaintycontinuous loadingThe paper presents an evaluation of synchronization issues when performing material testing machine calibration using continuous loading. A procedure for the compensation of a rangewide error in calibrated force values is proposed based on a correction factor determined from static and transient errors difference at a chosen force step. The procedure was applied for a calibration of a testing machine with a 20 kN force transducer and 200 N/s to 2000 N/s loading rates. The results show good performance of the compensation technique, reducing calibration errors to below 1% in non-synchronized signals even under unknown filter and delay setting.Elsevier Ltd.20212023-12-20 07:48:21Neznano17586sl© 2021 Published by Elsevier Ltd.
