摘　　要：通过平时的观察,发现教室中的折叠座椅使用时产生的机械能被浪费掉,为了研究如何将这部分机械能利用起来,以法拉第电磁感应定律为基本实验原理,运用机械设计知识,创新性地在教室座椅上,设计了一种通过座椅的开合带动处于磁场中的线圈转动,从而产生电流的环保型教室座椅发电装置,该装置将按压座椅产生的机械能转化为电能,达到发电的目的.理论计算得出,当按下座椅的平均耗时为1s,该装置的输出电压为10.8V,与实验测试得到装置的输出电压9.4V相近.研究表明,装置产生的输出电压与座椅被按下速度之间呈现正相关关系.It is investigated that the mechanical energy generated by the folding seat in the classroom is wasted.In order to research the way to use this mechanical energy,an environment friendly power generator device is designed based on the Faraday Law of electromagnetic induction and the theory of mechanology.The generator installed on the classroom seat will generate electric energy when the seat is pushed to drive the coil in a magnetic field,thus mechanical energy can be transformed into electric energy.The output voltage in the experimental measurement is 9.4V,which is similar to its theoretical value 10.8V based on the assumption that the time of pressing the seat down is 1second.According to our research,the positive correlation exists between the voltage and the angular velocity of the device.
