Studies On The Simulation And Effects Of Vibration About Steel Radial Tire

Vibration is an important using characteristic of the tire products affected bymany factors and how to control the resonance and noise caused by vibration isalways been the focus of tire industry. Tire technology and wear process, whichare always been neglected, influence the vibration directly. With the developmentof high performance tires, more and more attention has been paid to its vibrationproperty along its whole life. This article mainly studies the vibration response ofsteel radial tire (SRT), including the modal and shape, with the experimental andfinite element method (FEM), during producing and wearing process to find theinfluence of different factors, works as following:Firstly, TYABAS, the SRT vibration finite element analysis (FEA)pre-processing software, is developed. According to the complexity of SRT andelement in FEA cannot match the analysis precision, we develop TYABAS bycomputer language Python, which including functions such as meshing, boundarycondition and so on. It makes the boundary of material clearly and satisfies therequirement of coordination and continuity.Secondly, the SRT vibration FEA model has been established and verified.After establish the vibration Model using TYABAS and getting the analysisresults, compare the results between experimental and FEA model to illustrate thefeasibility of FEM and effectiveness of results.Thirdly, the influence of work conditions and belt structure are studied.Using simple variable method, inflation pressure, rolling speed and load indynamics are been studied to get the response of frequency. The results indicatethat inflation pressure has the more influence than rolling speed and load.According to the change of belt structure during molding in drum andvulcanization process, study the frequency under different distance and angle ofbelt. The results indicate that the frequency increases with the increasing ofdistance and angle.Finally, wear process has been studied. Establish the model about the rate ofwear with experiment, and friction power density based on tread rubber frictionmodel and FEM using friction subroutine UFRIC. Find the frequency responseabout different wear thickness during its full life suing vibration FEA model. Theresult shows that radial vibration increases with the wear thickness.
