PREDICTION OF RADIAL TIRE’S NATURAL FREQUENCIES
-
摘要: 一定充气压力下, 子午胎的固有频率是由其材料和结构本身确定的。鉴于橡胶材料的粘弹性性质, 本文中以胎体为弹性基础、把子午胎模拟成一个胎面层具有粘弹性的圆环弹性基础模型, 并在此模型的基础上建立频率方程。本模型预报出的频率值能与实验值吻合。

Abstract: The natural frequencies of a radial tire at a given pressure were determined in terms of the material and structure of the radial tire. With respect to viscoelsticity of rubber, the radial tire was modeled as a ring on elastic tire's body and viscoelastic tread. A natural frequency equation was created on the basis of this model. Experimental values of resonant frequencies at a given pressure are in agreement with the predicted values well.-
