本文主要研究动态质量测量系统的行为。本文的目的是提出一种能够再现楼板振动的动力学行为的系统动力学模型。将电磁力补偿系统的动力学近似为质量-弹簧-阻尼器系统,得到了系统的运动方程。模型参数也根据实验数据进行了估计。然后,将仿真结果与实际响应进行了比较。最后,对楼板振动的动力特性进行了探讨。
This paper focuses on behavior of a dynamic mass measurement system. The goal of this paper is to propose a dynamic model of the system, which can reproduce dynamic behavior to floor vibration. The dynamics of our system with electro-magnetic force compensation is approximated by a mass-spring-damper system, and an equation of motion is derived. Model parameters are also estimated from experimental data. Then, comparisons of the simulation results with the realistic responses are carried out. Finally, we explore the dynamic behavior to floor vibration.
