Abstract. In this paper, the e ect of shaft rotation on its natural frequency is investigated. Considering rotary inertia and gyroscopic momentum, the fourth order di erential equation representing the exural vibration ...

Abstract. A series of low speed wind tunnel tests were conducted to study the unsteady aerodynamic behavior of an airfoil sinusoidally oscillating in plunge. The experiments included measuring the surface pressure distribution ...

Abstract. Volume Of Fluid (VOF) is one of the most powerful methods to resolve free surface ows. In this study, a new algorithm is developed in a curvilinear coordinate system, which implements an implicit pressure ...

Abstract. In this study, the free vibration of moderately thick rectangular plates with several internal line supports was analyzed; the plates having twenty one possible boundary conditions (a combination of clamped, ...

Abstract. Certain strati ed charge divided chamber engines have a very small pre-chamber, equipped with a spark plug and a main chamber connected to the pre-chamber through nozzles. A theoretical model is presented in ...

Abstract. In this paper, a formulation is developed for obtaining the optimal trajectory of robot manipulators to maximize the load carrying capacity for a given point-to-point task. The presented method is based on open ...

Abstract. In this paper, a novel spatial six-degree-of freedom parallel manipulator actuated by three base-mounted partial spherical actuators is studied. This new parallel manipulator consists of a base platform and a ...

Abstract. Based on the instability of magnetic behavior through the concept of local exchange and hybridization, a new class of heavy fermion is constructed with a stable local magnetic ion, Gd". The lattice constant, ...
