Abstract:
The history of national and international research and development of piezoelectric dynamometers and the associated research carried out in the first author's group over 25 years are surveyed and presented. It mainly focuses on the applied fundamental theory of piezoelectric effects and the state-of-the-art achievements, such as the distribution of tangential sensitivity, the torsional effect of quartz crystals, and the models of physical effects on the transition between various forms of energy and so on. New product development of piezoelectric dynamometers within recent three years has been introduced including the YDXM-III97 type integral milling & grinding dynamometer, YDZ-II99 type drilling dynamometer without fixed rotating center, YDC-III2000 type three-dimensional small cutter arbor turning dynamometer used on numeric control machines. The relevant software and hardware for force-measuring system and the further research and development of piezoelectric dynamometers are presented.
