一、前言随着科研工作的发展,在振动测量工作中,不但要测量物体原地振动的各种物理量,如加速度、共振频率、以及在共振状态下构件的应变等等。还要求测量在行驶中,不同行驶速度下的上述物理量。为研究其动态特性提供必要的数据。为此,我们研制了四路四线无线遥测仪。本仪器除能对履带式车辆在行驶中进行振动测量外,还可以对其它构件的动态特性进行各种参量的测量。特别是在记录仪器不易接近,而专线传输又有困难的现场。
I. INTRODUCTION With the development of scientific research, in the vibration measurement work, not only to measure the in-situ vibration of a variety of physical quantities, such as acceleration, resonant frequency, as well as the components in the resonance state strain and so on. It is also required to measure the above physical quantities at different driving speeds while driving. To provide the necessary data to study its dynamics. To this end, we developed a four-way four-wire wireless telemetry. The instrument in addition to crawler-type vehicles in the vibration measurement, but also on the dynamic properties of other components for a variety of parameters measurement. Especially in the recording device is not easy to access, and green transmission and difficult scene.
