【Abstract】 Nowadays, with the appearance of new materials and products, the manufacturing has lain in an intensely competing social environment. It is that the molding and modifying technology together with green manufacturing and energy saving becomes the key study for the advanced manufacturing.In terms of the inherent characteristics of piezoelectric shock wave and the successful experience in other domain, this paper applies piezoelectric shock wave into Nanocomposites technologies. This paper mainly makes the following studies and experiments about piezoelectric shock wave generator.The first chapter reviews the invention and development of the piezoelectric shock wave generator. Then it introduces the primary content and meaning of the study.The second chapter expounds the designing principles and methods of the piezoelectric shock wave generator with piezoelectric transducer. Besides, also introduces the piezoelectric, match layer and cementation technology.The third chapter illustrates the design of piezoelectric shock wave generator power source. It also studies the primary circuit, high frequency signal generator,control mode and so on.In the fourth chapter, using reflecting target and absorbing target, we invent a novel ultrasonic power meter in order to exam and certify the piezoelectric shock wave generator.The fifth chapter introduces the experiment of epoxy/ SiO 2 Nanocomposites dispersion and cure with piezoelectric shock wave generator. At last, this paper summarizes the research achievements and raises a new hypothesis for the deep research of the piezoelectric shock wave generator.更多还原
