摘要
根据电磁振动原理,设计了一种新型混凝土电磁振动棒。介绍了电磁振动棒的机械结构和工作原理,同时详细设计了供电系统主电路和控制部分。主电路采用逆变器作为其核心部分,输出脉冲电流;控制部分以脉宽调制芯片TL494为核心产生驱动开关管导通的脉冲信号。经过现场测试,验证了设计的可行性。
A new type of electromagnetic vibrating spear mainly used for concrete was developed based on the principle of electronmagnetic vibration. The mechanical structure and working principle of the electromagnetic vibrating spear are introduced, and the main circuit of the power supply system and control part are particularly designed. The main circuit output pulse current with the inverter as its core, and the control part generate pulse signal driving switch tube active with pulse width modulation chip of TL494 as its core. The feasibility of the design is proved by field test.
