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。

Magnetic design and test should be considered in the design and making of a satellite,because the magnetic torques resulting from the interaction between the magnetic properties of the satellite and the ambient magnetic field tend to disturb its attitude.This paper presents the ambient field mapping method to determine a satellite magnetic moment.Its main point is to acquire experimentally and deduce mathematically the magnetic field data of a satellite in the limited region in earth's field.In order to do that,we must overcome two main difficulties: separating permanent moment from induced moment;effectively inhibiting noise of earth's field.This method has resolved these problems by using the following techniques in a better way:1,repeating measurement at original and inclined (or inverse) position.2,obtaining the difference between the outputs from the measuring probe and the reference probe.3,let the axis of the probe direct to the earth's field east,turning the test subject over 90° of angle to keep relative magnetic state between it and the probe.The results that have been attained by analysis and test indicate that the error is not more than 10% for magnetic moment above 500 mA-m2.It can be expected that the precision can be increased after improvement.

本文给出了在地磁场中测量卫星磁矩的环境磁场作图法。通过采用原位和斜置(或倒置)的重复测量、对测量探头和参考探头的输出作差值处理、使探头沿地磁场东西取向和试验体转置90°以保持它与探头的相对高斯态不变等方法,较好地解决了在地磁场中磁测碰到的两个主要技术难题:分离永磁矩和感磁矩,有效地抑制地磁场的噪声。并由试验表明,对于磁矩在500 mA-m~2以上的卫星,由该法给出的测量相对误差不大于10%。
