研制了一种采用无阻尼式动态吸振器的新型振动型质量测量系统。在所开发的系统中，将测量对象附加到振动器的惯性质量而不是吸振器质量。其优点是吸振器的调谐条件不受测量对象质量的影响。对所研制的系统在刚性基座和柔性结构上的测量精度进行了实验评估。结果表明，两种情况下的测量精度基本相同。研究还表明，通过将激励信号从零逐渐增大到测量幅值，可以减小转台在暂态时的振动。
A new vibration-type mass measurement system using 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 rigid 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.
