Torsional Vibrations in a Crank Shaft [PDF]
, 1991 In this paper, we analyze the torsion in the crank shaft of a gas compressor with one crank. The effect of damping will not be studied here. The geometry is as drawn in Fig. 1. Two forces are exerted on the shaft. First, it is at one end driven by a motor.

Advanced Science, EarlyView.A predictive model for 3D printability is developed by integrating rheological analysis, including the Large Amplitude Oscillatory Shear (LAOS) test, with machine learning. With prediction errors under 10%, the model shows that post‐extrusion recovery controls horizontal printability, while high‐strain‐rate nozzle flow dictates vertical printability ...

Influence of torsional-lateral coupling on stability behavior of geared rotor systems [PDF]
In high-performance turbomachinery trouble often arises because of unstable nonsynchronous lateral vibrations. The instabilities are mostly caused by oil-film bearings, clearance excitation, internal damping, annular pressure seals in pumps, or labyrinth

Wannier-Stark ladders in one-dimensional elastic systems
, 2006 The optical analogues of Bloch oscillations and their associated Wannier-Stark ladders have been recently analyzed. In this paper we propose an elastic realization of these ladders, employing for this purpose the torsional vibrations of specially ...

On a global classical solution of a quasilinear hyperbolic equation
International Journal of Mathematics and Mathematical Sciences, 1989 In this paper we establish the existence and uniqueness of global classical solutions for the equation which arises in the study of the extensional vibrations of thin rod, or torsional vibrations of thin rod.
