Energy scavengers developed at the University of Michigan can produce electricity from random vibrations. “The energy-harvesting devices are efficient at providing electrical power from arbitrary, non ...
Tiny generators could produce enough electricity from random, ambient vibrations to power a wristwatch, pacemaker or wireless sensor. Tiny generators developed at the University of Michigan could ...
Random vibration testing provides energy simultaneously at all frequencies. Vibration testing can help ensure that your new design will survive its intended environment. The problem is knowing how ...
Abstract: A finite element simulation model for stacked solder joints was established and subjected to random vibration modal analysis and stress-strain analysis. Based on the Manson high-cycle ...
Abstract: Earthquake excitation has evident randomness and also has strong fuzziness owing to the uncertainties in the definition of earthquake intensity and site soil classification. The proposed ...
1.- Determine characteristics of commercial sensors and actuators according to design. 2.- Design control algorithm. 3.- Design corresponding electronics to control the electromechanical system. 4.- ...
Vibration testing helps to predict how well a product will withstand its intended service or transportation environment. Some new vibration controllers have the capability to replicate data recorded ...
For RVT you need to use two file: RandomTest.py and RandomEvaluation.py. The RandomTest.py is used to create the acceleration needed for an envelope Power Spectral Density (PSD). Then, the script save ...
NOTE: Click on images or equations to make them larger. Last month’s column discussed the basics of simulating resonant or natural vibration frequencies as an introduction to performing advanced ...
