To　study　the　hysteresis　heat-generating　of　rubber　and　its　influence　on　rubber＇s　mechanical　properties,　based　on　the　analysis　of　physiological　mechanism　of　heat-generating　rubber,　heat　in　the　rotation　process　of　a　pair　of　squeezing　and　contact　rolling　steel-rubber　rollers　was　studied.　The　time-dependent　rising　regular　of　temperature　inside　rubber,　and　the　effect　of　rubber　hardness　and　thickness　parameters　on　its　heating　were　analyzed.　The　influence　of　the　rise　of　temperature　on　the　mechanical　properties　of　rubber　including　hardness　and　loss　factor　was　also　analyzed　though　the　experimental　data.　The　experiment　results　show　that　the　rubber　with　hardness　of　high　initial　value　will　get　more　temperature　rising,　and　the　rubber　with　small　value　thickness　will　get　more　temperature　rising,　and　the　temperature　rising　will　cause　the　reduce　of　rubber　hardness　and　the　increase　after　first　decrease　of　loss　factor.　©　2017,　Editorial　Department　of　Journal　of　Beijing　University　of　Technology.　All　right　reserved.
