Eliminating noise and controling vibration , gold plated brass pin , male plug , with duralumin to cut vibration 消除杂讯制震,铜镀金插片,公插, duralumin抑震材质使用,防磁体
3.
Based on a duralumin flexible beam with piezoelectric films attached , distributed parameter modal described by partial difference equations is builded , and then turned into a set of two order systems with the method of modal analyse . state feedback control and independent modal control is investigated . and simulation of the closed - loop system with thest two methods is performed in matlab 并用模态分析的方法，将系统的偏微分方程模型转化成了模态模型；研究了状态反馈和独立模态方法；进一步完善了软件界面以及软件功能；在实际系统中，应用状态反馈算法，有效抑制了悬臂梁在受到外界瞬时脉冲扰动和激振引起的一阶、二阶模态振动。
