This ebook comprises mechanism research and synthesis.
In mechanism research, a mobility technique is first systematically awarded. this technique, in response to the author's screw conception, proposed in 1997, of which the generality and validity was only proved lately, is a truly complicated factor, researched by means of a number of scientists during the last one hundred fifty years. the primary of kinematic impact coefficient and its latest advancements are defined. This principle is suitable for kinematic research of assorted 6-DOF and lower-mobility parallel manipulators. The singularities are labeled via a brand new standpoint, and growth in position-singularity and orientation-singularity is acknowledged. additionally, the idea that of over-determinate enter is proposed and a brand new approach to strength research in line with screw idea is gifted.
In mechanism synthesis, the synthesis for spatial parallel mechanisms is mentioned, and the synthesis approach to tricky 4-DOF and 5-DOF symmetric mechanisms, which used to be first recommend through the writer in 2002, is introduced intimately. in addition to, the three-order screw method and its house distribution of the kinematic screws for endless attainable motions of reduce mobility mechanisms are either analyzed.

A totally up to date model of the preferred Introduction to Tribology, the second one variation of this prime tribology textual content introduces the foremost advancements within the realizing and interpretation of friction, put on and lubrication. concerns of friction and put on were totally revised to incorporate contemporary research and information paintings, and friction mechanisms were reappraised in gentle of present advancements.
In this variation, the breakthroughs in tribology on the nano- and micro- point in addition to contemporary advancements in nanotechnology and magnetic garage applied sciences are brought. a brand new bankruptcy at the rising box of eco-friendly tribology and biomimetics is included.
- Introduces the subject of tribology from a mechanical engineering, mechanics and fabrics technology issues of view
- Newly up to date bankruptcy covers either the underlying idea and the present purposes of tribology to industry
- Updated write-up on nanotribology and nanotechnology and creation of a brand new bankruptcy on eco-friendly tribology and biomimetics
