摘要
工程翻新轮胎在使用过程中会有无数个振动,但一些频率较低的振动将会对其失效破坏产生较大影响,如果轮胎在100Hz以下共振,将会产生较大破坏。因此,分析工程翻新轮胎低阶振动频率及振型对实际应用的意义较大。构建工程车辆翻新轮胎的计算机几何模型、接触对模型、有限元分析模型,采用Lanczos法对工程翻新轮胎进行模态分析,数值模拟分析轮辋约束及地面接触约束两种工况下的前20阶固有频率和振型。得出以下结论:轮辋约束工况下,1、2、5、6、9、10、15、16、17阶振型为圆形,3、4、7、8、18、19、20阶振型为椭圆形,11、12阶振型为三角形,13、14阶振型为四边形,其中2~5阶、11~20阶振型的变化幅度较大;静态接地工况下,1、2、3、4、5、6、9、10、13、14、20阶振型为圆形,7、8阶振型为椭圆形,11、12阶振型为三角形,15、16阶振型为四边形,17、18、19阶振型为五边形,其中3~5阶的振型变化幅度较大。研究成果可为工程翻新轮胎的结构设计、使用性能及动力性能、失效机理分析提供重要理论指导。
There are numerous vibrations during the use of engineering refurbished tire,but some of the lower frequencies will have a greater impact on their failure and damage if the tire resonate below 100Hz.Therefore,it is of great significance to analyze the low vibration frequency and vibration type of engineering refurbished tire.The computer geometric models,contact pair models and finite element analysis model of engineering vehicle refurbished tire of the engineering vehicle were constructed.The mode analysis of engineering refurbished tire was performed by using Lanczos method,natural frequency and natural vibration of the first 20 order were analyzed using numerical simulation analysis method under the working condition of the wheel rim constraints and ground contact constraint.The following main conclusions are obtained：under the working condition of the wheel rim constraint,the vibration modes of 1,2,5,6,9,10,15,16 and 17 order are circular,the vibration modes of 3,4,7,8,18,19 and 20 order are elliptic,the vibration modes of 11 and 12 order are triangle,and the vibration modes of 13 and 14 order are quadrangle,and then the change range of vibration mode is great from the 2 th to 5 th and 11 th to 20 th order modes;under the static grounding working condition,the vibration modes of 1,2,3,4,5,6,9,10,13,14 and 20 order are circular,the vibration modes of 7 and 8 order are elliptic,the vibration modes of 11 and 12 order are triangle,the vibration modes of 15 and 16 order are quadrangle,the vibration modes of 17,18 and 19 order are pentagon,and then the change range of vibration mode is great from the 3 th to 5 th.The research results can provide an important theoretical guidance for the structural design,using and dynamic performance and failure mechanism analysis of the engineering refurbished tire.
