At　present,　the　calibration　of　most　torque　sensors　is　carried　out　in　an　ideal　laboratory　environment.　But　the　temperature　around　the　torque　sensor　can　vary　widely　in　practical　applications.　The　thermal　radiation　from　ambient　temperature　usually　causes　the　elastic　element　of　the　sensor　to　deviate　from　Hooke＇s　law　and　resulting　in　errors.　Based　on　this　problem,　we　establish　the　digital　simulation　and　an　artificial　system　of　a　certain　type　of　strain　torque　sensor　by　thermo-mechanical　coupled　digital　simulation　method,　and　we　calculate　the　time-temperature　distribution　models　and　the　time-elastic　modulus　distribution　model　of　sensors　under　different　working　conditions　by　finite　element　thermal　analysis　and　transient　force　analysis　method.　Finally,　we　summarize　some　change　rule　of　the　torque　sensor　parameters　like　elastic　modulus　or　shear　stress　with　temperature.　So　as　to　obtain　the　influence　mechanism　of　temperature　on　the　torque　sensor,　which　provides　a　basis　for　the　improvement　of　calibration　method.　©　2022　IEEE.
