Angular momentum of walking at different speeds
Human Movement Science, 2010Recently, researchers in robotics have used regulation of the angular momentum of body segments about the total body center of mass (CoM) to develop control strategies for bipedal gait. This work was spurred by reports finding that for a "large class" of human movement tasks, including standing, walking, and running the angular momentum is conserved ...

A robust capacitive angular speed sensor
IEEE Transactions on Instrumentation and Measurement, 1998This paper presents a contactless capacitive angular speed sensor for automotive applications. The sensor is based on a passive rotating electrode placed between two mechanically static and electrically active electrodes. The different characteristics of the charge transfer at various sensor positions is utilized as an input for the calculation of the ...

The measurement of instantaneous angular speed
Mechanical Systems and Signal Processing, 2005Many different methods have been developed for the measurement of angular speed. Each successive method has attempted to improve measurement performance using a different strategy to process encoder signals based on two basic principles: counting the number of pulses in a given time duration and measuring the elapsed time for a single cycle of encoder ...

Low Speed Bearings’ Instantaneous Angular Speed Behavior
2015This work describes shaft’s Instantaneous Angular Speed (IAS) behavior in the presence of a spall on bearing’s race at low speeds. It is shown that fault signature becomes more apparent in IAS signal when speed decreases and load increases. EEMD processing of the signal is implemented to overcome the shortcoming of IAS sensitivity at low loading ...

Digital Angular Speed Measurement Using Waveform Sampling
IEEE Transactions on Industrial Electronics, 1982A method of digital angular speed measurement based on waveform sampling utilizing an orthogonal pair of sinusoids is proposed in this paper. Details of the derivation and implementation of the technique are described. One of the earlier techniques of speed measurement is compared with the proposed waveform sampling technique by estimating the speed of

Instantaneous angular speed monitoring of electric motors
Journal of Quality in Maintenance Engineering, 2004This research presents the theory and implementation detail for the extraction of angular speed variations. In particular, band‐pass filtering, frequency shifting and analytic representation are addressed with simple mathematical equations. Finally, some case studies on a 3kW induction motor are investigated for healthy and faulty conditions.

Low speed bearings fault detection and size estimation using instantaneous angular speed
Journal of Vibration and Control, 2014The fault diagnosis and prognosis of low speed machines remains a difficult problem despite remarkable advances in the conditional monitoring domain. The Rolling-element bearing is a vital part of these machines and its failure is one of the main causes of machine breakdown.
