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.

This book was released on 2005 with total page 294 pages. Available in PDF, EPUB and Kindle. Book excerpt: The electromechanical model and the dynamic electromechanical drift model were applied to an existing design of a piezoelectric driven valveless micropump, where these models can be used as design tools for the physical design of micropumps to give the optimum flow rate or performance for high precision applications, such as biomedical dispensing devices. In addition, the inverse of the electromechanical model was developed and applied to the micropump design, where such a model can be used to obtain a desired input voltage for a prescribed flow rate. This model can be used as the framework to develop controllers for output flow rate and pressure regulation and control, potentially in both open loop and closed loop control. In this thesis first a simple resistor-capacitor (RC) model for PZT is presented. The model is used to assess the suitability of various models used throughout the literature. Piezoelectric actuators offer high stiffness, fast response times, high sensitivity, low wear and tear, and large force output. Unfortunately the electrical properties of lead zirconate titanate (PZT) changes significantly with an applied mechanical load disturbance and PZT suffers from hysteretic behaviour. In addition, piezoelectric actuators drift in open loop control. Therefore, in order to employ PZT actuators in high precision applications for improved regulation and control, and to achieve absolute positioning for long durations, models are required to characterize the behaviour of the material. An experimental test rig is developed and designed for the simultaneous application of an arbitrary input voltage and an arbitrary load to a PZT stack actuator test specimen. The test rig is used to develop and validate an electromechanical model for piezoelectric actuators, which accounts for hysteresis. The model also characterizes the coupled electromechanical effect of the sensing and actuating signals. In addition, a dynamic electromechanical model is developed to characterize the hysteresis and drift behaviour of PZT. The presented model closely captures the absolute output displacement of the PZT actuator to a variety of applied input voltage excitations.

This book was released on 2018-06-04 with total page 30 pages. Available in PDF, EPUB and Kindle. Book excerpt: This paper presents a procedure for modeling structures containing piezoelectric actuators using MSCMASTRAN and MATLAB. The paper describes the utility and functionality of one set of validated modeling tools. The tools described herein use MSCMASTRAN to model the structure with piezoelectric actuators and a thermally induced strain to model straining of the actuators due to an applied voltage field. MATLAB scripts are used to assemble the dynamic equations and to generate frequency response functions. The application of these tools is discussed using a cantilever aluminum beam with a surface mounted piezoelectric actuator as a sample problem. Software in the form of MSCINASTRAN DMAP input commands, MATLAB scripts, and a step-by-step procedure to solve the example problem are provided. Analysis results are generated in terms of frequency response functions from deflection and strain data as a function of input voltage to the actuator.Reaves, Mercedes C. and Horta, Lucas G.Langley Research CenterPIEZOELECTRIC ACTUATORS; ACTUATORS; MODELS; ELECTRIC POTENTIAL; FREQUENCY RESPONSE; TEMPERATURE EFFECTS; MODE

Download or read book Modeling Characterization and Design of Smart Material Driven Stick slip Actuation Mechanisms written by Leon M. Headings and published by . This book was released on 2005 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Both of the designs constructed utilize piezoelectric stacks driven by sawtooth waves to provide stick-slip contact between two partially threaded jaws and a 1/4-80 screw. The first mechanism design utilizes two piezoelectric stacks in a push-pull configuration. The motion of the two stacks is coupled through a lever amplification mechanism. The second design uses a single stack to directly drive the jaws without amplification. However, a second stack is oriented perpendicular to the first stack and driven with a triggered square wave. This stack varies the normal and thus frictional force between the jaws and screw, permitting more efficient sticking and slipping of the actuator. This allows for potential increases in both output speed and force. Actuator characterization is critical for the modeling, optimization, and comparison of actuator designs. This research reviews performance metrics proposed by various authors and expands an existing actuation efficiency model to incorporate an amplification mechanism. A physical apparatus for evaluating actuators is designed and test procedures are established. The performance of the prototype actuator designs is evaluated, leading to recommendations for future work.
