英语原文共 9 页, 自增制动系统的机理分析 摘要:辅助制动器与乘客的安全密切相关。尽管存在制动力矩不足和现有冲击力过大的问题,辅助制动,自增制动系统具有稳定,稳定的特点,可靠的制动,有利于乘客的安全。对这一点进行研究具有重要意义。自增制动系统中的机械装置。本文的运动学分析结合机械分析来研究两种静态下的制动扭矩和动态条件。等效制动扭矩测试和制动减速度还进行了测试以评估制动性能。结果表明向下制动符合规定。研究表明即使在制动转矩的理论值很小的情况下,自增式制动器仍符合规范,并具有稳定的制动过程以及有限的冲击力,得益于自增扭矩的综合作用。可见自增扭矩可以直接影响制动扭矩和最大减速度。 引言 辅助制动器是自动扶梯的重要安全部件。目前市场上流行的辅助制
附录B 外文原文 Bureaucracy has few fans. Walmart CEO Doug McMillon calls it “a villain.” Berkshire Hathaway vice chair Charlie Munger says its tentacles should be treated like “the cancers they so much resemble.” Jamie Dimon, the CEO of JPMorgan Chase, agrees that bureaucracy is “a disease.” These leaders understand that bureaucracy saps initiative, inhibits risk taking, and crushes creativity. Itrsquo;s a tax on human achievement. Though mindful of its evils, many people believe bureaucracy is unavoidable. Dimon remembers an outside adviser who defended it as the “necessary outcome of complex businesses operating in complex international and regulatory environments.” Indeed, since 1983 the number of managers, supervisors, and administrators in the U.S. workforce has grown by more than 100%, while the number of people in all other occupations has increased by just 44%. In a survey by Harvard Business Review, nearly two-thirds of respondents said their o
附录Y外文原文 Abstract Bulk material transportation requirements have continued to press the belt conveyor industry to carry higher tonnages over longer distances and more diverse routes. In order keep up, significant technology advances have been required in the field of system design, analysis and numerical simulation. The application of traditional components in non-traditional applications requiring horizontal curves and intermediate drives have changed and expanded belt conveyor possibilities. Examples of complex conveying applications along with the numerical tools required to insure reliability and availability will be reviewed. Structure design is the selection of materials and member type ,size, and configuration to carry loads in a safe and serviceable fashion .In general ,structural design implies the engineering of stationary objects such as buildings and bridges ,or objects that maybe mobile but have a rigid shape such as ship hulls and aircraft frames.

Design and fabrication of low cost filament winding machine Abstract In general, the composite pipes are fabricated using glass fiber and polyester resin matrix by hand lay-up and also by 2-axis filament winding machine. In this work, a filament winding machine was designed and developed for the fabrication of pipes and round shape specimens. A lathe-type machine and a wet winding method were used in the design of the machine. It provides a capability for producing pipe specimens with an internal diameter up to 100 mm and lengths up to 1000 mm. The range of the winding angle, or the fiber orientation angle, starts from 20 to 90 depending on the mandrel diameter used. Mandrel speed is kept constant as 13.6 revolutions per minute (rpm) while the speed of screw of delivery unit varies from 0 rpm to a maximum of 250 rpm. In the filament winding process used, a single glass roving is drawn through a bath of pre-catalyzed resin which is mounted on the lead screw by the rotating ma
附录B 外文原文 The community is based on a group of users who are brought together by the media to conduct information dissemination, emotional communication, culture and value sharing. Different stages of social development, advances in media technology, and the evolution of the community. The Internet has promoted the economic development of the fan community and fans, while the mobile Internet has extended the communitys functions and the communitys value has been enlarged, which has spawned the 'community economy.' The mobile Internet community presents new communication characteristics: cohesion and fission, the spread of emotional values, self-organizing communication and collaboration. The user community has had a transformative impact on all aspects of production, marketing, and consumption, namely: the production model of user participation, the marketing model of the brand community, and the consumption mode of experience-oriented, thus forming a self-organizing
