In this paper, the large-scale torque extrapolation estimation problem was studied by experiment and simulation. Firstly, two different types of torque transducers were placed on the torque measurement standard device, and the torque measurement points were taken and recorded at the corresponding values of 20 %, 50 % and 100 % of the full range respectively. Then, based on the changing trend of torque value and interpolation deviation in different range, the linear extrapolation estimation method was adopted, and the estimation model of large-scale torque was established. Based on the torque data in 20 % and 50 % of the full range in the experiment, the full range torque value was predicted by simulation and compared with the results in experiment. Finally, the effectiveness of the linear extrapolation estimation method was analyzed and compared, in order to provide an effective reference for the accuracy and traceability of large-scale measurement of torque transducers.</div></div>","PeriodicalId":34311,"journal":{"name":"Measurement Sensors","volume":"38 ","pages":"Article 101381"},"PeriodicalIF":0.0,"publicationDate":"2025-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144211957","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The study demonstrates that the uniform acceleration distribution in materials like steel and cemented carbide leads to more accurate calibration outcomes, the diameter and height of the mass block have a significant influence on the distribution of acceleration. The vibration frequency of sinusoidal force directly affects the dynamic calibration result of the sensitivity of the force sensor, and the natural frequency of standard devices of sinusoidal force calibration is affected by the mass block dramatically. Therefore, it is suggested that an international standard for dynamic calibration of force transducers based on sinusoidal methods should be formulated to resolve the differences between the relevant technical standards and the requirements of calibration items and methods for force transducers among various countries.
