基于摩擦功的全钢载重子午线轮胎的磨耗性能研究

Study on Wear Property of Truck and Bus Radial Tire Based on Friction Power

以12R22.5全钢载重子午线轮胎为研究对象,采用哈尔滨工业大学开发的轮胎系列有限元分析软件对轮胎的磨耗进行系统研究,给出了在静态、稳态、启动、制动、侧偏和转弯等不同工况条件下轮胎的摩擦功及磨耗方向。结果表明,工况条件对轮胎磨耗程度影响较大,由大到小依次为转弯、制动、启动、侧偏、稳态。另外,工况条件对轮胎横向磨耗分布有较大影响,特别是转弯和侧偏等工况条件。

Taking 12R22. 5 truck and bus radial tire as an example,tire wear was systematically studied using finite element analysis software developed by Harbin Institute of Technology. The tire friction power and wear direction were given under the conditions of static state, steady state, starting, braking,cornering and turning. The results indicated that working conditions influenced tire wear greatly, and in descending order, the conditions were listed as ： turning, braking, starting, cornering and steady state. In addition,the working conditions also had great impact on the lateral wear distribution of the tire, especially the turning and cornering working conditions.
