In order to solve these problems due to battery, this project engages in the research of tire -mounted mechanical-electrical transform mechanism, aims at transforming mechanical energy into electrical energy by a mechanical-electrical transform package which consists of vibrator (coil) and stator (magnet) on the basis of principle of electromagnetic induction to compensate energy consumption of batteries. Basing on the relationship of energy conservation, the sources of mechanical energy which could be used in the tire-mounted mechanical-electrical transform package is explored in this paper. As for the status and restrictive factors in tangential movement of vibrator, the method of rolling friction with that vibrator can overcome the centrifugal force in tangential movement is analyzed in detail and the experimental verification is carried out. The movable amplitude and energy of vibrator affecting the efficiency of energy transform are estimated. The experiments show that the energy transform mechanism in tangential movement of vibrator with rolling friction method is practical for engineering application.%为了解决电池能耗的制约问题,该文进行了轮胎内置运动生电机理的研究,旨在运用电磁感应原理由动子(线圈)和定子(磁铁)构成的运动生电组件把机械能转换成电能,为内置电池补充能耗.文中以能量守恒关系为出发点,对可被轮胎内置运动生电组件利用的机械能来源进行探索.针对动子切向运动的状态和制约因素,详细分析了使动子能克服离心力作切向运动的滚动摩擦方法并进行了实验验证,对影响换能效率的动子位移幅度和能量进行了估算.实验表明采用滚动摩擦所实现的动子切向运动换能机理具有工程应用价值.
