激励力矩的耦合及弹性结构角速度响应测量的实验研究

Experimental investigation into the exciting moment coupling and the response measurement for its angular velocity in elastic structure

本文首先给出了用磁致伸缩棒力矩激振器将激励力矩施加到被测结构上的三种耦合模式，然后用水平放置的有机玻璃悬臂梁结构作为实验对象，对不同的耦合模式进行了测量和对比分析．接着对弹性结构角速度响应的测量方法进行了研究，并设计了一个压电晶体角加速度计的原型．为了验证理论分析，作为一个例子，对一个有机玻璃悬臂梁结构的传递力矩导纳进行了测量．

In this paper, a comparative analysis is conducted for investigation of the results obtained from the application of the three different coupling patterns for measurement of the exciting moment exerted by a magnetostrictive rod moment actuator upon a horizontally mounted plexiglass cantilever beam structure. A piezoelectric crystal angular accelerometer is designed for investigation of the method for measuring the resulting angular velocity in the elastic structure. Measurement of the transfer moment mobility in the plexiglass cantilever beam structures is carried out as an illustrative example for theoretical verification.
