摘要:Abstract(#br)The vibration of an infinitely long beam with a large axial tension under a point harmonic load moving at a uniform speed is studied to find out the importance of bending rigidity of the beam. It is found analytically that the effect of bending stiffness of the beam ...

摘要:Abstract(#br)Rolling element bearing is widely used in rotating machines and any bearing defect therein can severely affect the overall machine performance. Vibration monitoring is often used to detect bearing faults. However, some rotor dynamic systems operate at very slow speed...

摘要:Abstract(#br)Numerical model based virtual prototype of a system can serve as a tool to generate huge amount of data which replace the dependence on expensive and often difficult to conduct experiments. However, the model must be accurate enough to substitute the experiments. The...

摘要:Abstract(#br)Performance of a shape memory alloy(SMA) bar as a vibration isolator is examined under isothermal and non-isothermal operating conditions. A novel state space formulation of thermomechanical model is presented. The displacement transmissibility of an isothermal isola...

摘要:Abstract(#br)A physical model of a type of commercially available magneto-rheological fluid based damper has been developed to study the input–output response characteristics. The impedance of the nonlinear device has been analyzed based on equivalent linearization method. T...

摘要:Abstract(#br)The instability due to parametric excitation from variable mesh stiffness in a gear pair system has been studied with the help of a six-degree-of-freedom translational–rotational model to consider the contribution of tooth sliding friction. A new harmonic balanc...

摘要:Abstract(#br)The usefulness of deliberate modification of the tooth profile of a spur gear pair in reducing the level of vibration is studied. The severity of vibration and noise at different operating conditions have been measured by different metrics namely dynamic mesh force, ...

摘要:Abstract(#br)Rolling element bearings are widely used in rotating machines and their faults can lead to excessive vibration levels and/or complete seizure of the machine. Under special operating conditions such as non-uniform or low speed shaft rotation, the available fault diagn...

摘要:Abstract(#br)Vibration analysis for diagnosis of faults in rolling element bearings is complicated when the rotor speed is variable or slow. In the former case, the time interval between the fault-induced impact responses in the vibration signal are non-uniform and the signal str...
