旋转超声振动加工中非接触电能传输特性研究
|
摘要
针对旋转超声振动加工中接触式电能传输方式存在的弊端,提出了一种非接触电能传输系统。建立了非接触电能传输松耦合感应模型,理论分析了电能传输效率的影响因素,对松耦合变压器原/副边进行了阻抗匹配;仿真分析了系统电压增益、原/副边功率及传输效率随负载和松耦合变压器设计参数的变化规律;实验研究了系统传输效率和电源频率、磁芯间距之间的影响关系,证明了方案的可行性。
For the disadvantages of contact power transmission in rotary ultrasonic vibration machining, a contactless power transmission system is proposed in this paper. A loosely coupled inductive model of contactless power transmission is established. The influence factors of energy utilization are analyzed based on theoretical analysis. Impedance matching is implemented on primary and secondary of loosely coupled transformer. The variation rules of voltage gain,primary/secondary side power and transmission efficiency with the load and design parameters of loosely coupled transformer are simulated. The relationship between the system transmission efficiency and power frequency,magnetic core spacing is studied by experiment. The feasibility of the proposed scheme is proved from experimental results.
