Advanced Vibration Measurement for Industrial Automation Systems

Multicopter Vibration Analysis Challenge

Multicopter drones experience significant vibration during operation. Excessive vibrations reduce flight stability and performance. Component deterioration accelerates with vibration exposure. Traditional measurement methods have limitations.

Research Methodology Development

Hiroshima University engineers created innovative measurement approach. They used stereo imaging for non-contact vibration analysis. Two high-speed cameras captured precise movement data. Digital Image Correlation processed thousands of measurement points.

• Two Mikrotron EoSens 2.0CXP2 cameras

Frequently Asked Questions

Q: How does 3D stereo imaging compare to traditional vibration sensors?

A: Stereo imaging provides full-field vibration data without physical contact, while traditional sensors like accelerometers only measure at attachment points and can affect the measured structure’s dynamics through added mass.

Q: What industrial applications benefit from non-contact vibration measurement?

A: Rotating machinery monitoring, precision manufacturing equipment, automotive component testing, and aerospace structures where traditional sensors cannot be installed or would interfere with operation.

Q: What technical specifications are critical for vibration imaging systems?

A: Frame rates exceeding 500 fps, high spatial resolution, precise camera synchronization, and robust image processing algorithms capable of handling thousands of measurement points simultaneously across three dimensions.
