This book was released on 2019 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Further improvements in high precision mass comparison are a recent issue in the dissemination chain of the mass standard. One of the most precise methods of mass comparison is achieved by the use of high precision electromagnetic force compensated (EMFC) weighing cells as part of mass comparators. The mechanics of EMFC weighing cells are based on compliant mechanisms with concentrated compliances in form of flexure hinges. Total mechanical stiffness and tilt sensitivity are limiting factors with regard to the resolution of EMFC weighing cells. In order to optimize their performance, the stiffness and the tilt sensitivity of the systems need to be minimized. Due to manufacturing restrictions and robustness requirements, a further reduction of the thickness of the pivots is not desirable. In this paper, an alternative to reduce stiffness and tilt sensitivity by adding trim weights in combination with an astasizing adjustment is presented. Based on the results of the investigations, a new planar monolithic mechanism for an EMFC weighing cell is designed, providing the possibility to adjust trim masses. The new mechanism is set up and adjusted according to the developed mechanical model. A parameter combination for a total stiffness slightly above zero and a tilt sensitivity close to zero is found. For the evaluation of the adjustment success and the vacuum compatibility, the system is tested under high vacuum conditions.

Available in PDF, EPUB and Kindle. Book excerpt: This book presents a computer-aided approach to the design of mechatronic systems. Its subject is an integrated modeling and simulation in a visual computer environment. Since the first edition, the simulation software changed enormously, became more user-friendly and easier to use. Therefore, a second edition became necessary taking these improvements into account. The modeling is based on system top-down and bottom-up approach. The mathematical models are generated in a form of differential-algebraic equations and solved using numerical and symbolic algebra methods. The integrated approach developed is applied to mechanical, electrical and control systems, multibody dynamics, and continuous systems.
Download or read book Sensors written by Jose Gerardo Rocha and published by BoD – Books on Demand. This book was released on 2008-12-01 with total page 456 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book describes some devices that are commonly identified as tactile or force sensors. This is achieved with different degrees of detail, in a unique and actual resource, through the description of different approaches to this type of sensors. Understanding the design and the working principles of the sensors described here requires a multidisciplinary background of electrical engineering, mechanical engineering, physics, biology, etc. An attempt has been made to place side by side the most pertinent information in order to reach a more productive reading not only for professionals dedicated to the design of tactile sensors, but also for all other sensor users, as for example, in the field of robotics. The latest technologies presented in this book are more focused on information readout and processing: as new materials, micro and sub-micro sensors are available, wireless transmission and processing of the sensorial information, as well as some innovative methodologies for obtaining and interpreting tactile information are also strongly evolving.

This book was released on 2024-08-09 with total page 174 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents orthotropic vibration modeling and analysis of carbon nanotubes (CNTs) which be helpful in applications such as oscillators and in non-destructive testing, and also vibrations characteristics of armchair double-walled CNT by means of nonlocal elasticity shell model. The nonlocal shell model is established by inferring the nonlocal elasticity equations in to Kelvin’s theory, which is our particular motivation. The suggested method to investigate the solution of fundamental Eigen relations is wave propagation, which is a well-known and efficient technique to develop the fundamental frequency equations. The frequencies of three different types of SWCNTs are calculated. Also, the vibrations of the chiral single-walled carbon nanotube (SWCNTs) with non-local theory using wave propagation approach is investigated. It has been investigated that by increasing the nonlocal parameter decreases the frequencies and on increasing the aspect ratio increases the frequencies throughout the computation frequencies of clamped-free lower than that of clamped-clamped. Carbon nanotubes have a variety of applications because of their distinctive molecular structure and show unique electronic and mechanical properties because of their curvature. Nanotubes and micro-beams can be cited as one of the very applicable micro- and nano-structures in various systems, namely, sensing devices, communications and the quantum mechanics. The application of the tiny structures, specifically, carbon nanotubes in the sensors and actuators enforce the engineers to study vibrational properties of those structures experimentally and theoretically. In addition, they are utilized in different fields such as bioengineering, tissue engineering, computer engineering, optics, energy and environmental systems.

Download or read book Handbook of Force Transducers written by Dan Mihai Ştefănescu and published by Springer Nature. This book was released on 2020-01-27 with total page 257 pages. Available in PDF, EPUB and Kindle. Book excerpt: Part I introduces the basic “Principles and Methods of Force Measurement” according to a classification into a dozen of force transducerstypes: resistive, inductive, capacitive, piezoelectric, electromagnetic, electrodynamic, magnetoelastic, galvanomagnetic (Hall-effect), vibrating wires, (micro)resonators, acoustic and gyroscopic. Two special chapters refer to force balance techniques and to combined methods in force measurement. Part II discusses the “(Strain Gauge) Force Transducers Components”, evolving from the classical force transducer to the digital / intelligent one, with the incorporation of three subsystems (sensors, electromechanics and informatics). The elastic element (EE) is the “heart” of the force transducer and basically determines its performance. A 12-type elastic element classification is proposed (stretched / compressed column or tube, bending beam, bending and/or torsion shaft, middle bent bar with fixed ends, shear beam, bending ring, yoke or frame, diaphragm, axial-stressed torus, axisymmetrical and voluminous EE), with emphasis on the optimum place of the strain gauges. The main properties of the associated Wheatstone bridge, best suited for the parametrical transducers, are examined, together with the appropriate electronic circuits for SGFTs. The handbook fills a gap in the field of Force Measurement, both experts and newcomers, no matter of their particular interest, finding a lot of useful and valuable subjects in the area of Force Transducers; in fact, it is the first specialized monograph in this inter- and multidisciplinary field.
