Abstract

In this paper we presented a method of high precision load measurement by dynamic crane scale. The basic point of this approach lies in the idea that the sampling average of dynamic load signal during a time interval between the maximum swing angles is a function of the maximum swing angle. The mass of goods is a constant factor of this function. By the function and the maximum swing angle calculation formula, the mass value of goods can be calculated under the dynamic condition. The experimental results indicated that the measurement precision of more than 0.1% F.S. can be achieved.
