摘要:

設計了一種基于模糊PID控制器和超磁致伸縮致動(dòng)器的車(chē)削振動(dòng)主動(dòng)控制系統,推導了超磁致伸縮致動(dòng)器和專(zhuān)用刀架的數學(xué)模型,并在Matlab環(huán)境下進(jìn)行建模仿真,當振動(dòng)頻率在50~100 Hz時(shí),仿真結果表明該控制系統能抑制振幅達50%以上；在現場(chǎng)車(chē)削試驗中,以普通45#鋼為車(chē)削工件,分別在轉速1 500 r/min、車(chē)削深度為0.07 mm和轉速3 000 r/min,車(chē)削深度為0.04 mm下,對車(chē)削振動(dòng)進(jìn)行主動(dòng)控制,結果證明所設計的車(chē)削振動(dòng)控制系統能夠抑制振動(dòng)幅度達30%以上。

Abstract:

A turning vibration active control system with fuzzy PID controller and giant magnetostrictive actuator(GMA) was designed. The mathematic models about the GMA actuator and special tool post were derived. The simulation was performed on Matlab, and results show that the controlling system can reduce the vibration amplitude by more than 50% when the vibration frequency ranges from 50Hz to 100Hz. Testing was implemented on a general turning machine, in which the workpiece was 45# steel. The turning vibration was effectively controlled when the rotation speed is 1 500r/min or 3 000r/min and the cutting depth is 0.07mm or 0.04mm respectively. Testing results verifies that the designed turning vibration controlling system can effectively suppress the amplitude of the vibration by more than 30%.
