| In recent years, the phenomenon of traffic accident occurred with high frequency due to the fact that tyre generated more heat and its temperature rose higher. Tyre researchers and designers are struggling for an effective way to control the tyre heat generation under the circumstance of ensuring the low rolling resistance and high wet grabs. So the research of tyre temperature field is an important research problem. However, the research foundation of this problem is to know all kinds of thermal property parameters in advance. This paper's main focus is to comprehensively think over all kinds of tyre rubber and through installation of thermal property parameter database, to make the progress of program transformation and calculation of tyre temperature field more easier, to perfect the finite element analysis system of tyre temperature field.Rubber recipes about this research are ten commonly used tyre rubber materials. The temperature measure range is 25℃～105℃and thermal property parameters are measured by transient LFA Nanoflash. Based on the verification of its validity, we saved them as the original data of thermal property parameter database.Heat generation rate calculation about this research is ten common used tyre rubber materials mentioned above. The temperature measure range is -20℃～100℃and the measure frequency are 5Hz, 10Hz, 16.666Hz, 25Hz and 33.333Hz. We use DMA experiment to measure storage modulate (E'), loss modulate (E") and loss factor (tanδ). We used the formula of q=Q/t=fπE"ε02 to calculate heat generation rate. Then we saved them as experience data in thermal property parameter database.Set up tyre rubber thermal property database system based on relational data model. The main task about this part including following works: Focus on the system purpose about the tyre robber thermal property parameters database's development, we analyzed its functional structure; After compared with the character of the operating and database system in prevail, we set up tyre rubber thermal property database system based on relational data model. In the same time, we explained the key technology and database security problem about the system development. The main function of this system is to store the experimental data mentioned above. Simultaneity, this system can dynamically response to the performance of record append, delete, update etc. Through temperature and diversified thermal property parameters simulation, the users can analysis the tyre diversified rubber material heat generate trend. In addition, system designed the data tables and data reports about diverse tyre rubber, users can append and delete it at any moment. Users can examine the data reports either by the way of exporting Excel or by direct data report print.Put tyre rubber thermal property parameter database into the FEATT (Finite element analysis tyre temperature) system application, to make the process of tyre temperature simulation more precisely. FEATT designed by former research group deemed diverse tyre rubber as the constant number in the process of tyre temperature simulate calculation. However, duo to the fact that practical tyre rubber often endured different quantity of heat in the process of tyre rolling. So they will represent different thermal physical character. We deemed every kind of tyre rubber as single factor, thus we can effectively make up the disadvantages about deemed diverse tyre rubber as constant number only through the way of transfer the response tyre rubber in the process of tyre temperature calculation. By doing this, we can effectively accomplish tyre temperature simulation more precisely.Brief introduction about FEATT system after comprehensively thinking over diverse tyre rubber's influence on the tyre temperature field. Based on brief introduction of FEATT system, we contrast the process of calculate tyre temperature field by deeming thermal property parameters as the constant number with calculated it by comprehensively thinking over diverse thermal property parameter's influence. The result show that they had resemble heat generation trend, but the grid temperature of deeming thermal property parameters as the constant number is much higher than comprehensively thinking over diverse thermal property parameter's influence. In this paper, focus on the tyre temperature field calculate instance outputted by FEATT and the tyre temperature field calculate instance outputted by tyre rotation experiment, we contrasted and analysis its character in detail. Although there are some error in the tyre temperature field calculated number, but the error can be controlled in a common range, so this adequately testified its accuracy and validity. In addition, according to the results outputted by the two methods, in relation to the tyre practical working condition, we analysis to the tyre temperature field's heat generation character.
