以梁的振动控制为背景,构造了一种智能元件,它们有预期欲控制的若干模态线性组合的几何形状,可传感多个振型输出并构成反馈输入,从而实现了对结构振动的主动控制。数值算例表明。它对结构的振动能形成有效的抑制,有较大的实用价值。 Based on the vibration control of a beam, an intelligent element is constructed, which has the geometric shapes of a few linear combinations of modalities to be controlled, and can sense the output of multiple modes and form the feedback input, so as to realize the structural vibration Active control. Numerical examples show. It can effectively suppress the vibration of the structure and has great practical value.
