【摘要】 本课题针对影响汽车轮胎橡胶机械性能的温度老化模型进行了一定深度的理论研究，并进一步研究轮胎的在滑动、滚动时的温度场的数学模型，在理论上论证了温度、压力是影响轮胎行使安全性能的重要因素，并以其作为最终的监测对象。 建立了以微控制器为核心，并由温度传感器、压力传感器、无线射频收发芯片为输入输出接口电路组成的轮胎安全状态在线监测系统。 系统采用多传感器获取数据，提高了系统处理数据的可信度，为系统的正常可靠运行提供了技术支持；各种软硬件抗干扰的设计以及软件的结构化设计，为系统安全、可靠运行与维护提供了保障。更多还原

【Abstract】 The paper studies the degradation rule of physical mechanical property of vulcanizate during the period of heat ageing, which involves the relationship between the property, variable temperature and time. The analytic expressions for the frictional temperature rise of the interface were presented according to the theory of heat conduction of solid when a tire slides of rolls along the road. Finally, the value of temperature and pressure is used to monitor the tire’s status.In order to measure the condition of the tire in real time, MCU, digital thermometer, and wireless radio frequency technology is used in this new system.Multi-Sensor technology is introduced this system, to gain more information of the tire. Hardware and software Anti EMI method is used to enhance the system’s reliability.更多还原
