Analysis of Tire Vibration by Using a Hybrid Two-Dimensional Finite Element Based on Composite Shell Theory

摘要: It has been shown experimentally that the vibration of a tire in region near contact patch can be represented by set decaying waves, each associated with particular crosssectional mode. Thus, modeled as lossy waveguide which waves propagate circumferential direction. may therefore computationally efficient to analyze vibration, especially close patch, using hybrid finite element model cross-section is approximated two-dimensional elements while wave-like solution assumed Here, was formulated based on composite shell theory: particular, circular conical formulated. The inflation pressure acting inner surface included considering both residual stresses and non-linear terms strain-displacement relations. dispersion relations for obtained FE were compared those from full, three-dimensional model. analysis made yields results agreement
