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 ...

In this paper, we investigated the technical problem of recovery overlength and heavy load conveying booms self-unloading ships. A method folding boom with a hydraulic-four-bar mechanism is presented, by using mathematical model for optimization velocity stationary ADAMS software, data results were obtained. The multi-objective index introduced, discussed. showed that parameters such as angular...

In this paper a novel nonlinear controller for position and vibration control of flexible-link mechanisms is introduced. The proposed strategy model-free does not require the measurement elastic deformation mechanism, since relies only on knowledge angular actuator its time derivative, which can be measured simply with quadrature encoder. conditions closed-loop stability are evaluated using Lya...

In the present work, optimal balancing of planar six-bar mechanism is investigated to minimize fluctuations shaking force and moment. An optimization problem formulated for by developing an objective function. The genetic algorithm MINITAB software were used solve problem. selection weighting factors has a crucial role obtain optimum values design parameters. Two sets considered as per contribu...

Motivated by the first search for rare charged-current $B$ decay to four leptons, $\ell \bar{\nu}_\ell \ell^{(\prime)} \bar{\ell}^{(\prime)}$, we calculate amplitude with factorization methods. We obtain $B\to \gamma^*$ form factors, which depend on invariant masses of two lepton pairs, at leading power in an expansion $\Lambda_{\rm QCD}/m_b$ next-to-leading order $\alpha_s$, and $\mathcal{O}(\...

This paper presents design modification to the existing standard wheelchair by incorporating an improved propulsion system and also braking and tilting systems that allow its full control with only one hand. The proposed design has the propulsion system with a chain drive powered through a four-bar linkage driven by the main handle. The desired direction of motion is obtained by moving the leve...
