Industrial robotic manipulators in pick-and-place applications require short settling times to achieve high productivity. The fluctuating reaction forces and moments on the base of a dynamically unbalanced manipulator, however, cause vibrations, leading increased times. These vibrations can be eliminated with dynamic balancing, which is achieved, general, addition counter-masses counter-inertia...

Abstract This work introduced a new hand prosthesis architecture able to achieve an opposite and lateral grasp by using single actuator. An analysis of the prostheses, as well movements classically performed in daily life at allows us focus our on these two types grasp. A lockable passive joint is moved user switch between The location thumb was defined thanks 3D scans four extreme positions. m...

This study attempted to establish an optimal design and perform dynamic analysis for a spring-actuated cam-linkage composite mechanism in rated 12 kV, 25 kA vacuum circuit breaker (VCB). The of the VCB involves two steps: first step stiffness closing springs cam profile, based on three-order polynomial motion curve follower; second four-bar linkage. To minimize surplus work operating mechanism,...

At present, multi-bar linkage mechanism is one of the most important directions of mechanical presses’ development. Utilizing the typical multi-linkage drawing mechanism of the plunger slide and compounding its parameters scientifically are a fairly effective way to realize the drawing technology demand. This paper established kinematics mode of the six-bar drawing mechanism by bar-group method...

In this paper, the dynamic analysis of a translating five-bar linkage mechanism is presented. The model developed with applied force to crank arm resolved into two principal planes, that is, x- and y- directions resulting reaction forces moments at pin joints determined various acceleration 0, 10, 20, 30 40 m/s2 in direction as well opposite rotation. It was observed horizontal were decreasing ...
