研制了一种新型无阻尼动态减振器振动式质量测量系统。在所开发的系统中，测量对象附着在振动发生器的惯性质量上，而不是附着在吸收质量上。它的优点是吸收器的调谐条件不受测量对象质量的影响。对所研制的系统在固定在大型基座和柔性结构上时的测量精度进行了实验估计。结果表明，两种情况下的测量精度几乎相同。研究还表明，通过将激励信号从零逐渐增大到一个测量幅值，可以减小工作台在瞬态时的振动。ASME版权所有©2003
A new vibration-type mass measurement system with an undamped dynamic vibration absorber was developed. In the developed system, a measurement object is attached to the inertial mass of the vibration generator instead of the absorber mass. It has an advantage that the tuning condition of the absorber is not influenced by the mass of measurement objects. The measurement accuracy of the developed system was estimated experimentally when it was fixed on a massive base and on a flexible structure. The results demonstrated that measurement accuracy was almost same in both the cases. It was also shown that the vibration of the table in transient states was reduced by increasing the excitation signal gradually from zero to an amplitude for measurement.Copyright © 2003 by ASME
