Against the backdrop of increasing focus on environmental issues,manufacturers, distributors and those involved in the product distribution are calling for mechanism not only to control conventional channel of logistics process-ranging from manufacturing to disposal-but also for a mechanism that will continuously monitor the lifecycle of the *** frequency identification(RFID) in this scenario is being looked at with increased interest more than ever before:The technology in itself is not new but its mass application in field of manufacturing automation and product lifecycle management is *** paper focuses on RFID technology with view to examine its possible applications in the fields of manufacturing automation and product lifecycle management(PLM).It also takes a look at some of its current applications and their outcome.

Hexagon head bolts and nuts with flange have been widely used,especially in the automobile *** is provably because of their highly expected performance against loosening caused by return rotation or permanent deformation at me vicinity of ***,it is inferable that the performance mentioned above is directly affected by the bearing-surface pressure *** of the factors which influence remarkably on the bearing-surface pressure distribution character is the concavity angleφ.Although its value range is specified in the standards such as JIS and ISO,the basis is not necessarily clear *** this research,influences of the concavity angle on the bearing-surface pressure distribution are analyzed in detail by a FEM,and their basic characteristics are clarified.
