The optimization of the position and the magnitude of the clamping forces in machining fixtures
This paper presents a method which allows the optimization of the position and magnitude of the clamping forces for a specific case of processing: milling of a canal in a prismatic workpiece, using a multi- objective method, implemented with ANSYS software. The design variables are location dimensions of clamping elements, whose range of variation ...

An analysis of the oscillatory movements of the suspension ropes for an elevator with parabolic speed modeling and continuous deceleration
In order to insure passengers' security and smooth functioning, elevators benefit from speed modeling. The paper aims to compare the evolution of the kinematic parameters (acceleration, speed, amplitude) of the oscillatory movements performed by the suspension ropes of the elevator cabin, considering speed variation at start and stop realized using...

Fuzzy control strategy for secondary cooling of continuous steel casting
The purpose of this paper is to create an original fuzzy solution on the existing structure of the control system of continuous casting that eliminates fissures in the poured material from the secondary cooling of steel. For this purpose a system was conceived with three fuzzy database decision rules, which by analyzing a series of measurements tak...
