Tedrie A miniature bearing experts. Harris, an introduction to the

Tedrie A. Harris, graduated from Pennsylvania state university to major in mechanical engineering, bachelor of science degree in 1953 and 1954 received Gu Shi degree, after graduation to enter united aircraft corporation Hamilton standards department as experimental development engineer. Later enter into Westinghouse electronics brady atomic energy laboratory for analysis and design engineers. Joined in 1960 is located in Pennsylvania in Philadelphia, Pennsylvania state of SKF industrial company, served as director of engineer. During the period of SKF, in several key management job position: analysis service manager; Public data system, special bearing, director of the department, product technology and quality always, SKF, general manager of tribology websites, MRC bearing ( In the United States) Engineering and research vice President, in glass standard fort to SKF headquarters, director of the group of information system and the executive director of engineering and research center in the Netherlands, etc. From SKF after retirement in 1991 was as professor of mechanical engineering at the university of Pennsylvania, in the teaching of machine design and tribology course in the university and specializing in the moving contact tribology fields of study, retired again until 2001. In recent years, as engineering application consultants and mechanical engineering and vocational education, the continuing education activities for the engineers to teach at the university of bearing technology courses. Published 67 technology works, most of which is about the wave dynamic bearing. In 1965 and 1968, received the brush and lubrication engineers association outstanding technical paper award, in 2001 the American machine 楲 engineers association ( ASME) Friction credits will be outstanding technical paper award, in 2002 and won the award for outstanding research ASME. Actively participate in many technology organization's activities, including antifriction bearing manufacturers association ( Now the ABMA) Brush, ASME, and ASME lubrication research committee, was elected to a senior member of the ASME 1973, also served as ASME rubbing brush, and tribological branch chairman of the board of the nomination and supervision has three patents in the United States. Michael N. Kotzalas graduated from Pennsylvania state university, a bachelor of science degree in 1994 and in 199 received a bachelor's degree, get a Ph. D. Degree in 1999, three degrees are major in mechanical engineering. During this period, the dynamic bearing performance analysis is the focus of the study and research, including high acceleration under the condition of the ball and roller bearing dynamics simulation and experiment maintain bearing under the condition of remaining with tertiary algorithm. After graduation into the Timken company engaged in research and development of the recent work for the department of industrial bearings, now responsible for industrial bearings provide advanced products design and application support, more important is engaged in the development of new products and the analysis algorithm. At the same time of writing this book, won two patents of cylindrical roller bearing design. Outside of work, but also to participate in the activities of industrial association, the American society of mechanical engineers ( ASME) Member, is now published, chairman of the committee, rolling bearing technology committee, at the same time as the friction and lubrication engineers association ( STLE) Awards committee. Have authority in professional magazines and a meeting of essays published 10 papers, to that end, ASME tribological branch best paper award in 2001; Hodson of STLE award in 2003 and 200. In addition, also participated in the us bearing manufacturers association ( ABMA) Work, is also the short lecture 'bearing technology advanced concept' lecture teacher
