Torsional Vibrations of Shells of Revolution
Journal of Applied Mechanics, 1961Torsional-vibration modes are uncoupled from the bending and extensional modes in thin shells of revolution. The solution for the uncoupled torsional modes then depends upon a linear second-order differential equation. The governing equation is subsequently solved for the frequencies of a conical shell.

Vibrational machining with torsional spindle vibrations
Russian Engineering Research, 2016The use of a pulsed variable-speed drive as a vibrational drive is studied theoretically and experimentally. The design of a transmission with controlled velocity fluctuation is considered.

Torsional vibration of acrolein
Transactions of the Faraday Society, 1966The sub-bands of the torsional vibration of acrolein have been resolved. The marked degradation indicates a change of about 2.7% in the rotational constant A in the first torsionally excited state. This results in the R branch being much more intense than the P branch.

The results of a successful experimental search for Φ − bell modes are reported. Some apparently extraordinary inconsistencies observed between the different components of such modes are explained in terms of small asymmetries of the bell. It is shown that Φ − modes could easily be mistaken for π modes.

The construction of an internal-combustion engine is such as to make it susceptible to resonant torsional oscillation of the crankshaft. When an engine is operated near a critical speed, that is, a speed at which the pulsations produced by each cylinder excite the natural frequency of the crankshaft, excessive torsional amplitudes are developed which

Torsional Vibration and Related Coupled Vibration
2019Torsional vibrations are often problematic in transient responses when a rotor-bearing system starts up. The vibration is more predominant and unavoidable in geared rotor systems. Though torsional vibration poses long-term problems, new methods of rotor design have been established by employing the transfer matrix method, which are capable of ...
