一种谐振式称重传感器数学模型的建立

The Foundation of a Mathematical Model of a Syntonic Weighting Sensor

文中介绍了一种由双平行梁和振弦组成的新型谐振式称重传感器。根据这种传感器的特点 ,重点分析了传感器所称物体重量和振弦所受张力之间的关系 。

This paper introduces a syntonic weighting sensor which is composed of vibrant bowstring and double-balanced girder. According to the characteristic of the sensor, the relationship between the weight of the object which is measured and the tension which the vibrant bowstring sustains is analyzed, and the mathematical model of the relationship between vibrant bowstring's inherent frequency and the weight of the measured object is founded.
