本文研究了地面振动条件下的快速、高精度质量测量问题。为了减小楼板振动的影响，一般在称重传感器附近安装测量楼板振动的传感器。对这两个传感器的输出信号进行处理，并计算出加权质量。然而，这两种传感器的动态特性大体上不同，动态特性的不同会影响测量精度。为了在不损失快速性的前提下提高质量测量的精度，将相对动态补偿法应用于质量测量问题，提出了两种利用相对动态补偿法进行质量测量的方法。实验结果验证了该方法的可行性。
This paper concerns the problem of the fast and high accurate mass measurement under the conditions of floor vibration. In order to reduce the influence of floor vibration, a sensor which measures floor vibration is generally installed near the weighing sensor. The output signals from these two sensors are processed, and weighed mass is calculated. However, the dynamics of these two sensors are different in general, and the difference of the dynamics influences measurement accuracy. In order to improve the accuracy of mass measurement without losing the quickness, the authors apply the method of relative dynamic compensation to the problem, and propose two methods of mass measurement by using relative dynamic compensation. As a result, the feasibility of the methods is verified by experiment.
