This paper describes the criteria selected to give priority, in National Institute of standard and Technology (NIST)and (MSID)terms, to the standards activities that NIST and Msid do or should support. There are criteria for judging the quality of the standard itself, independent of how applicable to the Nsf mission. Other criteria are designed to help msid decide whether or not to participate in a standard's development. A computer-aided, decision-analysis tool was used to show that computer assistance would be useful to make decisions when many variables impact that decision 在 Manufacturing Technology之下的 Tooling, Machinery&To栏目中有条关于液力操织装 置的研究报告的介绍。 Hydraulic manipulator design, analysis, and control at Oak. Ridge National Laboratory To meet the increased payload capacities demanded by present-day tasks, manipulator designers have turmed to hydraulics as a means of actuation. Hydraulics have always been the actuator of choice when designing heavy-hife construction and mining equipment such as bulldozers backhoes and tunneling device. In order to successfully design, build, and deploy a new hydraulic manipulator (or subsystem ) sophisticated modeling, analysis and control experiments are usually needed. To support the development and deployment of new hydraulic manipulators, Oak Ridge National Laboratory(ORNL) has outfitted a significant experimental laboratory and has developed the software capability for research into hydraulic manipulators, hydraulc actuators, hydraulic systems, modehng of hydraulic systems and hydraulic controls. The hydraulic laboratory at ORNL has three different manipulators. First is a 6-Degree-of-Freedom(6-DoF), multi-planer, teleoperated, flexible controls test bed used for the development of waste tankclean-up manipulator controls, thermal studies, system characterization, and manipulator tracking. Finally is a human amplifer test bed used for the development of an entire new class of teleoperated systems. To compliment the hard ware in the hy developed a hydraulics simulation capability including a custom package to model the hydraulic systems
hydraulic manipulator developments at ORnl, describes the hydraulic laboratory, discusses the use of the equipment within the laboratory, and presents some of the initial results from experiments and modeling associated with these hydraulic manipulators. Included are some of the results from the development of the human amplifier/de-amplifier concepts, the characterization of the thermal sensitivity of hydraulic systems, and end-point tracking accuracy studies. Experimental and analytical results are included 现在NIS还在因待网上为用户提供这些报告的检索服务。 图34是美国国家技术情报服务局(Urlhttp:/www.nts.gov)的主页。选择AboutnTi可 以了解N提供的服务。 msb51Mw了!好数以[机工伟 区 敌高 is, rev/ U.S. Department of Commerce National Tochnical Information Servke Search Quick Ord BEST SELLERS PAONDCI FAMILES NTIS Electronic Catalog.search for Place Your order and order online Government Web sites.search Pickup Your Dow purchased downloads E· Mail Announcements weekly NTIS E-Alerts.stay current in FREE Best selle :34 National Technical Information Service How NTIS Helps Whether you are a research scientist, corporate librarian, or government engineer, NT!
