中文摘要：
设计了一种电磁式振动发电机结构,利用质量-弹簧-阻尼模型对振动发电机结构进行了数学建模,分析了电磁式振动发电机进行了机电特性,并仿真计算了正弦振动位移激励下线圈的输出电动势。结果表明,在模型基础上,发电机的输出感应电动势与输入位移激励具有相同的变化规律,说明机械能较好地传递到了电能。对设计并制作的样机进行了实验研究,发电机在振动频率10 Hz,振幅10 mm的正弦位移激励作用下,同一侧单组线圈、双组串联线圈的输出电动势峰峰值和有效值分别为3.437 V、7.684 V和0.710 V、1.988 V,实验表明,实验数值和仿真数值近似而且波形规律相同。
英文摘要：
electromagnetic vibration generator was proposed and its mathematical structure wasdesignedby usingthe spring-mass-damper structure,its electromechanical characteristics was also analyzed. The output EMF of the coil was simulated by the sine vibration displacement excitation. The results show that output EMF of the generator and the input displacement excitation have the same rules,which indicate that the mechanical energy can be transferred to the electrical energy. A prototype was tested under the sinusoidal vibration with amplitude 10 mm and frequency 10 Hz. The peak-to-peak value and the effective value of output EMF of the single group coiland double series coil are 3. 437 V,7. 684 V and 0. 710 V,1. 988 V,respectively. The experimental results are consistent with the simulation results.
