In　this　paper,　the　dynamic　and　static　mechanical　properties　and　thermal　properties　of　rubber　materials　used　in　tires　were　tested,　the　experimental　data　were　measured　and　the　performance　characterization　was　completed,　which　laid　a　foundation　for　the　accurate　completion　of　tire　finite　element　modeling　and　simulation.　Shimazu　universal　electronic　testing　machine　was　used　to　carry　out　cyclic　stretching　under　multiple　strains　on　each　rubber.　When　the　stress-strain　curve　reached　a　stable　state,　the　last　tensile　curve　was　taken　as　the　experimental　curve.　Three　common　constitutive　models　were　used　to　fit　the　experimental　data,　and　the　best　fitting　YEOH　model　was　selected　to　characterize　the　static　mechanical　properties　of　rubber　materials.　Secondly,　the　viscoelastic　parameters　of　the　tire　at　three　frequencies　corresponding　to　three　speeds　were　tested　by　the　dynamic　thermomechanical　analyzer,　and　the　variation　curves　of　the　Hysteresis　coefficients　(tan)　at　each　frequency　with　the　rise　of　temperature　were　obtained.　And　average　the　points　of　the　curve　to　get　the　average　value　which　will　be　used　in　the　following　calculation.　Finally,　the　specific　heat　and　thermal　diffusion　coefficient　of　the　compound　were　measured　by　laser　heat　conduction　instrument,　and　the　density　of　the　compound　was　measured　by　drainage　method　based　on　the　principle　of　hydrostatics.　The　thermal　conductivity　coefficient　was　calculated　by　formula.　　©　2023　The　Authors.
