An impact rotary motor based on a fiber torsional piezoelectric actuator

Review of Scientific Instruments, 2009
A prototype small impact rotary motor has been fabricated based on a newly developed torsional actuator which is 15.0 mm long and 1.0 mm in diameter. The motor can rotate when it is powered with a saw-shaped voltage. The experimental results show that its angular speed is proportional to both the driving voltage’s amplitude and the frequency under 1 ...

Torsional Impacts on Quaterthiophene Segments Confined within Peptidic Nanostructures

Langmuir, 2019
The co-assembly behavior of peptide-π-peptide and peptide-alkyl-peptide triblock molecules that form one-dimensional (1D) nanostructures under acidic, aqueous environments is dependent on the peptide sequence and the torsional constraints imposed within the nanomaterial volume.

Torsional vibration induced with the position dependent impacts

2022
The important issue of the torsional vibration induced with impacts which depend on position is investigated in terms of nonlinearities that can still be handled with modal superposition. The considered models involve non-classical damping and rigid body modes.

Nonlinear oscillations of the torsion oscillator with impact masses

1997
This paper deals with nonlinear oscillations of the torsion oscillator with reciprocal rigidly connected impact masses. It is assumed that two impulses occur at one interval of the disturbing torsion moment. The asymptotic Krilow-Bogolyubov-Mitropolyskiy method is applied, along with the stereomechanical impact theory for the inclusion of impact ...
