| 摘 要： | 人们愈来愈认识到,机器和其它振动源,向支撑和与之相连接的结构发射的结构声,除了平动成份之外,还有转动成份。众所周知,由于转动分量不易于激发和测量,所以很难对它评价。本文介绍一种由两根平行的磁伸缩棒构成的力矩激励器,并利用一个传递函数来研究它的特性和提出一个物理量一

| Abstract: | It is increasingly recognized that machines and other vibrational sources can impart structure-borne sound power into supporting and connected structures through rotational components of excitation as well as translational components.It is well known that the rotational components are difficult to estimate since moments are not easy to generate and measure.ln this paper a prototype moment actuator is introduced.It consists of two parallel rods of giant magnetostrictive material.The Performance of the actuator has been investigated by means of a transfer function involving magnitude and phase.A quantity, |
