本文考虑了一个平面结构的模态滤波使用点传感器设计用于提取一个特定的模态振幅的结构。本文的目的是建立基于点传感器的模态滤波器的设计过程。就像分布式模态传感器在感测潜力方面超过点传感器一样，处理和维护是令人讨厌的。科普这一问题，本文提出了一种易于操作和维护的点传感器模态滤波设计方法，发现只需遵循作者提出的分布式模态传感器的设计步骤，即可实现点传感器的模态滤波设计。还发现，点传感器完全取代分布式传感器的模态滤波在感兴趣的频率范围内。通过实验验证了基于点传感器的模态滤波方法的有效性。
This paper considers the modal filtering of a planar structure using point sensors designed for extracting a particular modal amplitude of the structure. It is purpose of this paper to establish the design procedure of a modal filtering based upon point sensors. Much as a distributed modal sensor outstrips a point sensor in the sensing potential, the handling and maintenance are odious. To cope with this problem, this paper presents a design methodology of modal filtering using point sensors easy to handle and maintain it. It is found that modal filtering design of point sensors can be achieved by simply following the design procedure of distributed modal sensors already presented by the authors. It is also found that point sensors perfectly replace the distributed sensors for modal filtering in the frequency range of interest. Experiment is conducted, demonstrating the validity of the point sensor-based modal filtering.
