1、大连交通大学信息工程学院2010届本科生毕业设计（论文）外文翻译Standards for Piezoelectric Ceramic MaterialsThis document details some of the standards related activities for piezoelectric materials, mainly bulk ceramic types. Standards related purely to quartz have been omitted, in order to limit the size of the task. The produc
2、tion of standards, particularly international ones, is a long and unrewarding business, and that they ever become standards is a tribute to the persistence of a small number of individuals. Consequently the existence or not of a standard in a particular area is not solely because of the need for suc
3、h a standard, but is due to the concerted effort of these individuals. Also because of the need to keep documents current, if years after publication of a standard there is nobody prepared to maintain this document then there is a danger it will be withdrawn or cancelled. This situation is reflected
4、 in the piezoelectric materials standards area, where there are strong groups in Europe (CENELEC) and America (IEEE-UFFC), but some of the most quoted standards have recently been withdrawn ( IEEE 176-1987, IEEE 180-1986, MIL-STD 1376B (SH).Standards organisations with Piezoelectric related standard
5、sCENELEC CENELEC is the European Committee for Electrotechnical Standardization and It has been officially recognised as the European Standards Organisation in its field by the European Commission in Directive 83/189/EEC.A comprehensive series of piezoelectric standards are being developed for CENEL
6、EC under BTTF 63-2. There are two working groups in this committee and it is WG-2 that is producing standards related to piezoelectric materials, under the stewardship of Wanda Wolny. At the time of writing the first three are close to being approved by the various national committees. As with most
7、standards within CENELEC there are English, French and German versions of these standards.prEN 50324-1:2001 Piezoelectric properties of ceramic materials and components - Part 1: Definitions and Classifications This standard relates to piezoelectric transducer ceramics for application both as transm

They are used for generation and transmission of acoustic signals, for achievement of ultrasonic effects, for transmission of signals in communication electronics, for sensors and actuators, and used for generation

Commonly used shapes include discs, rectangular plates, bars, tubes, cylinders and hemispheres as well as bending elements (circular and rectangular), sandwiches and monolithic mul

11、EN 50324-1 Definitions and classification. Methods of measurement for specific dielectric, piezoelectric and elastic coefficients are generally applicable to piezoelectric ceramics.The polycrystalline nature of ceramics, statistical fluctuations in composition and the influence of the manufacturing
12、process, result in specified material coefficients being typical mean values. These values are provided for design information only.Piezoelectric transducers can have widely differing shapes and may be employed in a range of vibrational modes. Material parameters however, are measured on simple test
13、pieces, (discs, rods) using specific geometric anmd electrical boundary conditions. Consequently, the results of the tests provide basic material parameters only and must be used as a guide to the actual properties of manufactured commercial components.prEN 50324-3:2001 Piezoelectric properties of

15、f piezoelectric ceramics material only, and not the characterization of a complete assembled transducer.The selection of a material for a given power application is difficult and the advice given in section 2 is mainly indicative.prEN 50ZZZ-1 (BTTF 63-2(CONV)12) Properties of multilayer actuators -

IEEE-UFFC The IEEE-UFFC is the Ultrasonics, Ferroelectrics and Frequency Control section of the Institute of Electrical and Electron
34、ics Engineers. The IEEE published some of the most quoted standards related to piezoelectric and ferroelectric materials, including176-1987 IEEE Standard on Piezoelectricity Description 180-1986 IEEE Standard Definitions of Primary Ferroelectric Electric Terms Both these standards have been withdraw

36、Dr Stewart Sherrit (JPL). The aim is to develop new ways of analysing loss through use of complex impedance and to write new IEEE standard based on the analysis. Details of this can be found at the UTMR website. A Draft of the IEEE standard on Ferroelectricity This is a definition of terms for ferro

It is still widely referred to as the source of of the various Navy types for piezoelectric materials.There is also some standards development going
39、on at the UTMR although it is not clear what form these standards will eventually be published as.Committee on Standard Protocols for Single Crystal Piezoelectrics This is coordinated by Dr Lynn Ewart-Paine (NUWC) on behalf of Dr Wallace Smith - ONR and is aimed at producing a protocol for the calcu

VAMAS VAMAS is the Versailles Project on Advanced Materials and Standards and supports world trade in products dependant on advanced materials technologies, through International collaborative project
41、s aimed at providing the technical basis for harmonized measurements, testing, specifications, and standards. The pre-standards research activities of VAMAS are organized into technical committees called Technical Working Areas (TWAs) which are approved by the a steering committee and led by Interna
42、tional Chairmen. A recent technical working area, TWA 24 Performance Related Properties for Electro-Ceramics is chaired by Dr. Markys Cain, and there are a number of proposed projects in this area directly related to piezoelectrics.A new VAMAS project - An International Intercomparison of Direct Pie
43、zoelectric Coefficient using the Berlincourt Method., has just started. The objective is to determine the experimental variability in the measurement of the piezoelectric coefficient of electroceramic materials via the standard method described as the Berlincourt Method. See the TWA 24 home page for
44、 more details.The VAMAS TWA-24 home page is hosted at NPL. EIA The Electronic Industries Alliance (EIA) is a national trade organization that includes the full spectrum of U.S. manufacturers, representing more than 80% of the electronics industry. There are some standards related to multilayer capac

Factors influencing performance as temperature, voltage (a.c. and d.c.), temperature-voltage, ageing, and frequency

Other topics as piezoelectric properties, corona, dielectric absorption, reliability, and applications are described extensively.Standards organisations with no active content related to piezoelectric materialsANSI ANSI, the American National Standards Institute, is a priva
47、te, non-profit organization that administers and coordinates the U.S. voluntary standardization and conformity assessment system. ANSI is the official U.S. representative to the International Accreditation Forum (IAF), the International Organization for Standardization (ISO) and, via the U.S. Nation
48、al Committee, the International Electrotechnical Commission (IEC). As a result the most of the piezoelectric related work is already covered in the IEC standards.ISO The International Organization for Standardization (ISO) is a worldwide federation of national standards bodies from some 140 countrie
49、s, one from each country. ISO is a non-governmental organization established in 1947. The mission of ISO is to promote the development of standardization and related activities in the world with a view to facilitating the international exchange of goods and services, and to developing cooperation in the spheres of intellectual, scientific, technological and economic activity.
