Dynamic modeling and experiment of a new type of parallel servo press considering gravity counterbalance
The large capacity servo press is traditionally realized by means of redundant actuation, however there exist the over-constraint problem and interference among actuators, which increases the control difficult...

Performance analytical study of the dual screws actuation mechanism
This paper presents a dual screw actuation mechanism (DSAM) wherein two screws actuate the common sliding platform by connecting two screw nuts with a gear pair. Two dimensionless parameters, namely, the gear ...

Design of mechanical presses driven by multi-servomotor
This paper proposes a so-called multi-servomotor parallel driven scheme to construct high capacity mechanical presses. The design method is based on the combination of dual screw actuation unit, parallel mecha...

Designing Domain Work Breakdown Structure (DWBS) Using Neural Networks
Work breakdown structures are the basis of project management. But there are few researches on the methods or tools to design work breakdown structures effectively. In this paper, a framework which employs neu...
