摘　　要： 振动研磨在工作过程中具有宽频谱、高振强的振动性能,但由于振动磨系统复杂的机械结构,实际振动波形与理论输出的激振波形存在明显的差异,致使振动电机发热、弹簧断裂等危险事件的发生。为解决振动磨系统对振强、振幅的控制不能产生具有一定频率的振动波,设计了一种基于STM32的高性能、低能耗的振动磨机超前控制系统,放大处理由传感器采集的振动信号,通过设置许用值范围,拟合并调整实际波形后输出安全的激振波,实时监测振动磨的振动状态,防止振动磨系统在共振点附近工作,提高了系统的安全性和高效性。 In the process of vibrational grind requires a vibration performance of a broadband spectrum and a high vibration intensity, but the actual vibration-waveform is quite different than the theoretical one in result of the complex mechanical structure of the vibrational grinding system, causing the risk events of vibration motor heating, spring fractured and so on. A new design of advanced control system based on STM32 for vibration grinding , which is high performance and low energy consumption , was developed to solve the problem of that the vibration intensity and amplitude control cannot produce certain frequency of the vibration wave. The system amplifies the detected vibration signal by sensors, and adjusts the actual curve fitting before outputting safety shock wave by setting the range of allowable value, to realize real-time monitoring the state of the vibration grinding, which prevents system runs near the resonance point and greatly improves the security and efficiency of the system.
