摘要
采用更高强度的塑料替换橡胶制备轮胎,为轮胎轻量化提供了新的方向。幅板式全塑轮胎具有高强度和低噪声等优越性能。文章利用Abaqus软件建立幅板式全塑轮胎有限元模型,并对其进行了显式动力学分析,探究了其瞬态滚动性能;从分析结果中提取其表面振动加速度作为边界条件,导入LMS Virtual.Lab Acoustics软件,采用声学间接边界元法进行了滚动噪声分析,并探究了其声场分布特性。分析结果表明,幅板式全塑轮胎显式瞬态滚动性能表现出类周期性;近场噪声具有方向辐射特性,且与观测点距离呈现负相关性。文章对于轮胎轻量化提供了一定的参考和理论数据指导,为全塑轮胎工程化提供了科学依据。
The use of higher strength plastics instead of rubber to produce tires provided a new direction for lightweight tires. The full-plastic tire with wheel spoke had many excellent performances such as high-strength and low-noise. The FEM of full-plastic tire with wheel spoke was established by ABAQUS. The dynamic analysis of the tire was carried out. The transient rolling performance was also explored. The surface vibration acceleration of full-plastic tire was extracted from the results of dynamic analysis as the boundary condition which imported into the LMS Virtual. Lab Acoustics. The acoustic indirect BEM was used for the rolling noise analysis of full-plastic tire with wheel spoke. The distribution characteristics of the sound field was also explored. The results showed that the explicit transient rolling performance was the class periodicity. The near-field noise had a directional radiation characteristic and had a negative correlation with the distance of the observation point. Certain reference and theoretical data for the lightweight of tires and scientific basis for the engineering of plastic tires were provided.
