结构物的原型和模型振动试验,通常利用电磁式激振器作为产生激振力的换能器件。电磁式激振器的输出特性,往往用力常数来表达。根据输入电流及力常数来确定电磁式激振器施于试验物体上的激振力是相当粗糙的。因为,在振动频率较高的情况下,一方面,电磁式激振器本身的运动部分已不再是一个简单的单自由度体系,输出力的情况较复杂;另一方面,激振力在通过传力杆传递的过程中,由于传力杆本身的弹性变形,也将损耗一部分能量。此外,还由于安装不妥的原因,也将产生相当大的摩擦损耗。而且,上述这些因素通常随频率而变。所以,电磁式激振器的输出力并不等于传至试验物体上的激振力,同时,激振力的波形与输入电流的波形也有失真观象。为了保证试验结果可靠正确,必须直接测定电磁式激振器施于试验体上的激振力。为此,在吸收国外动态测力传感器研制经验的基础上,应用国产压电陶瓷材料,研制成了TDJ-30动态测力传感器。本文将介绍它的结构,工作原理及主要特性。
