At present there appears to be a need for research conducted on the effects of vibration on the contractile ability of skeletal muscle tissue. The aim of this study was to address this issue by examining the effects of a superimposed muscle/tendon vibration at 50.42±1.16 Hz (acceleration 13.24 ± 0.18ms(-2): displacement ≈5mm) on muscular activation and maximal isometric contraction. Sixteen par...
Rotating machinery vibration analysis involves a convolute mixture because of the propagation medium, and the signals recorded by sensors in an industrial application are often disrupted by the environment. Deconvolution is a signal processing method for convolution of vibration sources, spectral kurtosis is a statistical tool which can indicate the presence of series of transients and their lo...
Vibration based condition monitoring refers to the use of in situ non-destructive sensing and analysis of system characteristics – in the time, frequency or modal domains – for the purpose of detecting changes, which may indicate damage or degradation. In the field of civil engineering, monitoring systems have the potential to facilitate the more economical management and maintenance of modern ...
Stepper motor performance can be compromised by noise and vibration, but an advanced high-torque micro-stepping algorithm can minimise the impact of both noise and vibration as well as increasing the resolution of the rotations. The embedded microcontroller which hosts the micro-stepper algorithm also provides additional flexibility to integrate current-limiting as well as adjusting the drive c...
As the 2nd report, we present a practical calculation method for torsional vibration of highly damped system with rubber couplings. This calculation system, constructed by a modal analysis technique, outputs frequency response characteristics, forced vibration responses, and mode animations. In respect of a damping model and calculation accuracy, it was verified that the assumption of general v...
This paper describes the concept and the characteristics of a newly developed touch-sensitive display which supports vibro-tactile feedback. This new touch-sensitive display named ‘Vibration Touch’ was developed to improve the uneasy operation of touch-sensitive displays due to lack of tactile feedback. Vibro-tactile feedback is realized by a combination of solenoid and spring which is directly...
