VIBRATION DETECTION DEVICE, VIBRATION CHARACTERISTIC MEASUREMENT SYSTEM, AND VIBRATION CHARACTERISTIC MEASUREMENT METHOD

摘要

PROBLEM TO BE SOLVED: To achieve the measurement of a vibration characteristic at the same time at two or more characteristic measurement spots with a small workload.;SOLUTION: A vibration detection device 1 is installed on a surface of a structure, and detects a vibration for calculating the vibration characteristic at a characteristic measurement spot of the structure. The vibration detection device includes: vibration detection units 2 more than the number of vibration detection spots required for calculating the vibration characteristic at two or more characteristic measurement spots on the surface of the structure; and a connection unit 3 for mutually interconnecting the respective vibration detection units at an interval corresponding to the distance between the respective vibration detection spots on the surface of the structure.;SELECTED DRAWING: Figure 1;COPYRIGHT: (C)2018,JPO&INPIT
