This book was released on 1996-11-30 with total page 366 pages. Available in PDF, EPUB and Kindle. Book excerpt: Remarkable developments have taken place in the field of mechatronics in recent years. As symbolized by the "Janglish (Japanese English)" word, mechatronics, the technology and the social adaptation for introducing electronics into mechanics has been readily accepted in Japan. Currently robots are producing many products under computer control in Japanese factories, and supermarkets are utilizing automation systems for sample displays and sales. Further, the fast paced change in semiconductor chip technology has given rise to the need for micro-displacement positioning techniques. Actuators utilizing piezoelectridelectrostrictive effects are expected to meet these needs in mechanical components in the next micro mechatronic age. This book, in English, builds on my earlier publications concerned with ceramic actuators. The first edition titled "Essentials for Development and Applications of Piezoelectric Actuators" was published in 1984 through the Japan Industrial Technology Center. The second edition "PiezoelectriclElectrostrictive Actuators" published in Japanese through Morikita Pub. Co. (Tokyo) became one of the best sellers in that company in 1986, and was then translated into Korean. The problem solving edition "Piezoelectric Actuators -Problem Solving" was also published through Morikita, which was sold in conjunction with a 60 minute video tape to provide easy understanding.

Available in PDF, EPUB and Kindle. Book excerpt: As one of the pioneers of "Piezoelectric Actuators", I have contributed to the commercialization of various products for over 45 years, including million-selling devices, micro-ultrasonic motors for smart-phone camera modules by Samsung Electromechanics, piezoelectric transformers for backlight inverters by Apple laptops, multilayer PZT actuators for diesel injection valves by Denso Corporation, and piezoelectric energy harvesting modules for Programable Air-Burst Munition by the US Army. During the development period for "piezoelectric actuators and transformers," I found that the bottleneck for device miniaturization was heat generation under a high-power drive condition. Thus, in parallel to the piezo-actuator developments, I have been developing various high-power density piezo-ceramic materials with the loss mechanism clarification. Hence, I considered that it was time to organize a textbook based on the previous studies, including my materials development philosophy to stimulate younger generations to reach to the energy density of up to 100 W/cm3 in the future. Increasing efficiency and saving energy and space (compactness) are one of the important approaches in this 21st-century "sustainable society." High-Power Piezoelectrics and Loss Mechanisims introduces the theoretical background of piezoelectrics, electromechanical phenomenology, loss mechanisms, practical materials, device designs, drive and characterization techniques, and typical applications, and looks forward to the future perspectives in this field. This book is NOT an overall review of this area, but it focuses on important and basic ideas under my development philosophy to understand how to design and develop high-power piezoelectric materials and devices. This textbook is designed for self-learning by the reader aided by the availability of: • Chapter Essentials – Summary for quick memory recovery • Check Points – Answers are provided in the Appendix • Example Problems – To enhance the reader’s understanding with full, detailed solutions • Chapter Problems – For the final exam or further consideration

Book excerpt: Smart materials and structures are widely employed in vibration control, shape control, health monitoring, micropositioning and many other fields. Piezoelectric ceramics are the most popular smart materials that provide favorable performances and low prices. In this thesis, two issues related to the application of piezoelectric ceramic actuators are addressed. One is the shape control of a composite beam under thermal loading using PZT (Lead Zirconate Titanate, a kind of piezoelectric ceramic) actuators. The other is Preisach hysteresis modeling of a Thunder actuator (a curved pre-stressed piezoelectric ceramic actuator) system. Both numerical and experimental studies of shape control of a composite beam with thermally induced deformation using PZT actuators are presented in this work. Finite element analyses are performed with the consideration of the coupled effects of structural, electric, and thermal fields on the composite beam. These analyses include static coupled field modeling of the beam with PZT actuation, transient modeling of the beam under thermal loading, and static coupled field modeling of the beam with thermal distortion and simultaneous PZT actuation to correct this distortion. Correspondingly, experiments are conducted to study PZT actuation effect, thermal effect, and active thermal distortion compensation using PZT actuators. Finite element and experimental results agree well and demonstrate that the proposed method can actively perform structural shape control in the presence of thermal distortion. As observed in the experiments of the composite beam under PZT actuation, piezoceramic actuators exhibit hysteresis nonlinearity. In this thesis, Preisach hysteresis modeling of a thunder actuator system is investigated and validated through experiments. First, a series of tests is conducted to study the hysteresis properties of the Thunder actuator system. The classical Preisach model is then applied to simulate the static hysteresis behavior of this system. The good agreement between the tested and predicted curves show this model is effective for modeling the hysteresis of the Thunder actuator system. Subsequently, the numerical inverse classical Preisach model is applied to the real time microposition tracking control of this system. Experimental results show that control accuracy with hysteresis compensation is greatly improved compared to that without hysteresis compensation.
