Parametric Identification of a Vibratory System With a Clearance
(The American Society of Mechanical Engineers (ASME), 1993)An analytical and experimental investigation of a vibratory system with a clearance was conducted. A finite element model and an equivalent single-degree-of-freedom closed-form solution were used ... -
Timoshenko Beam Modeling for Parameter Estimation of NASA Mini-Mast Truss
(The American Society of Mechanical Engineers (ASME), 1993)In this paper a distributed parameter model for the estimation of modal characteristics of NASA Mini-Mast truss is proposed. A closed-form solution of the Timoshenko beam equation, for a uniform ... -
Effect of Axial Vibrations on the Dynamics of a Helical Gear Pair
(The American Society of Mechanical Engineers (ASME), 1993)In this paper, a linear dynamic model of a helical gear pair has been developed. The model accounts for the shaft and bearing flexibilities, and the dynamic coupling among the transverse, ... -
Propagation of Impact-Induced Longitudinal Waves in Mechanical Systems With Variable Kinematic Structure
(The American Society of Mechanical Engineers (ASME), 1993)In previous publications by the authors of this paper it was shown that elastic media become dispersive as the result of the coupling between the finite rotation and the elastic deformation. ... -
Dynamic Response of an Axially Moving Beam Coupled to Hydrodynamic Bearings
(The American Society of Mechanical Engineers (ASME), 1993)The vibration response of a distributed axially moving beam, controlled through distributed hydrodynamic bearing forces, is analyzed by the transfer function method. In the axially moving beam, ... -
