轮胎胎体层的剪切模量研究

Prediction of Bodys Shear Modulus of Radial Tire

轮胎是一个具有粘弹性性质的橡胶复合材料结构体，结构比较复杂，研究其动态性能涉及到轮胎的一些宏观力学性能。本文用胎体层的组分材料基本材料性能参量和内胎的充气压力，预报了含有内胎的胎体层的宏观切向刚度和当量剪切模量。其预报值与实验值吻合很好。

A tire is composite and very complex structure with viscoelasticity. Reserch on its dynamic response is diffcult, especially, the prediction of macroscopic mechanic performances of a tire. In this paper prediction of macroscopic torsional modulus of tires body contained pneumatic tube of tire is made by the properties of tires constitutes and pressure. Experimental value of the tubes contacted length is agreement with the predicted value well.
