Mechanical Dynamic Laboratory
Developing methods of analyzing no-contact, no-fracture vibration experiments using laser technology
We are engaged in theoretical and experimental research on dynamic analyses related to mechanical mechanics, vibration engineering and acoustic engineering. Our goals are to drastically enhance analytical techniques by developing new experimental technologies and adding value to existing ones. To that end, we use laser-induced plasmas to develop no-contact, no-fracture vibroacoustic analytical technology. These methods can be used to identify transmission pathways that take into account the degree of rotational freedom, detect damage to airplane structures, analyze combustion vibration in rocket engines, and evaluate the quality of fruits and vegetables.
