Engineering machinery is characterized by high load frequency, large amplitude, and long continuous working time, which requires high anti-loosening performance of bolts. In this paper, based on ...

Nanostring discovered that transmits vibrations in cascade: the future of more sensitive, accurate, and innovative sensors.

A horse’s whinny can sound like two calls at once. One part sits low and rough, like a familiar mammal voice. Another rides ...

Scientists at TU Delft have designed a nanostring resonator that, when driven at its lowest vibration frequency, quietly funnels energy through a chain of higher modes all the way up to the fifth, ...

Abstract: This paper presents a model for estimating the perceived intensity of a superimposed dual-frequency vibration from the perceived intensities of its two component vibrations. Based on the ...

Abstract: The piezoelectric actuator exhibits both linear dynamics of creep and vibration and nonlinear dynamics of hysteresis. The model identification from experiments can compensate uncertainties ...
