Past, Present & Future
--20th Anniversary of APVC's

Yoshihiro Narita
(Hokkaido University, Japan,
Professor Emeritus)
The Asia Pacific Vibration Conference (APVC) is a biennial event that puts special emphasis on the field of vibration engineering and science. It has served as a platform for researchers at both universities and companies, engineers and practitioners to disseminate their latest findings. Actually, it started in 1985 as a part of “Kikai Rikigaku Kouenkai” (JSME domestic meeting on mechanical vibration) and since then, it has expanded as Asia Vibration Conference and later “Pacific” was added to broaden the covered areas. Nine countries and regions have been selected as conference venues. This conference is a pioneer of many international conferences titled as “Asia” or “Pacific” that have started later in JSME, and clearly the past huge success was brought by the researchers in the past and the cooperation with many researchers in Eastern and South-eastern Asian countries.
In this special lecture, it is hoped that we all have opportunities to look back the history of APVC’s to congratulate “Twentieth Anniverssary”, and we analyze the issues that Asian researchers stand on and will solve for. Also, with young promising researchers here, we would like to contemplate the future of the conference and help us create new ideas in this rapidly changing World.

Harnessing Piezoelectric Circuitry to Bridge the Mechanical and Electrical Domains for Vibration Energy Manipulation and Structural Health Monitoring

Jiong Tang
(University of Connecticut, USA,
Professor)
Piezoelectric transducers feature two-way electromechanical coupling that can seamless join the mechanical and electrical domains together. One can directly integrate circuitry elements to piezoelectric transducers embedded in the host structure to favorably alter the structural dynamic behaviors for control and inverse analysis purposes. In this talk, the basic concept of piezoelectric circuitry is introduced, with example applications to passive and active vibration controls. Subsequently, two recent efforts will be presented in detail. In the first effort, periodically arranged locally resonant unit cells utilizing piezoelectric circuitry, known as piezoelectric metamaterials, are designed, analyzed, and experimentally validated to facilitate various wave manipulations in a structure. The challenges and progresses of mechatronic synthesis for piezoelectric metamaterials are highlighted. In the second effort, taking advantage of the tunable nature of piezoelectric circuitry, a new adaptive piezoelectric impedance based damage identification methodology is formed, which combines tunable circuitry synthesis with first-principle modeling, multi-objective optimization, and reinforcement learning. The talk is concluded by outlining remaining challenges and opportunities.
