At first, the framework of alarm pretreatment system of optical transport network is discussed, then three function blocks of alarm pretreatment system are analyzed, they are alarm information database-, network topology information database and alarm correlation analysis. At last, Delphi 7.0 and SQL Server 2000 are used to achieve alarm pretreatment system of optical transport network; and experiment...
Based on high speed micro turn-milling complex machine tool and machining characteristic of micro parts, the reconfigurable theory and other related technologies are discussed in this dissertation to implement integrity machining and enhance machining efficiency. The general function analysis of micro turn-milling complex machining tool is done and it is the research foundation of universe technologies...
A virtual prototype of a certain caterpillar drive system is established based on virtual prototype technology in the article, the dynamic load spectrums in operation on different work sections of drive system gears are obtained through a simulation riding test. Applying finite element technology on three-dimensional contact stress dynamic analysis, the course of contact stress in flank of tooth area...
