2入力のIoTセンサーを用いた片持ち梁のモード形状の観察

Key Points

• The main aim is to develop a cost-effective technique for visualizing mode shapes using IoT devices in vibration diagnostics.
• Developed a low-cost two-channel acceleration sensor module.
• Used IoT devices to collect data on the mode shapes of a cantilever beam.
• Changed the placement of acceleration sensors on the cantilever beam to observe phase difference changes.
• Successfully visualized the mode shapes of the cantilever beam using the IoT sensors.
• Detected phase differences associated with changes in mode shapes due to sensor placement.
