Microwave energy has been demonstrated to be able to assist mechanical rock breaking in geotechnical and mining engineering.The aim of this research is to study the influences of the interaction between microwave energy and rocks on the performance of disc cutters on a TBM (tunnel boring machine).By applying an open-type microwave-induced fracturin
Influence of Wheelset Structural Flexibility on High-speedEMUs Curve-passing Performance
In order to study the influence of the torsional mode, bending mode and umbrella mode of the wheelsets on the vehicle curvepassingperformance, the vehicle-track system dynamics models were established, in which, the wheelsets structures were considered as rigidbody and flexible body respectively.The curve-passing performance of the vehicle was asse
A Novel Surface Recovery Algorithm for Dual Wavelength White LED in Vertical Scanning Interferometry (VSI)
The two peaks characteristic of yellow and blue light in the spectrum of dual-wavelength white light emitting diodes (LEDs) introduce distinctive features to the interference signal of white light scanning interferometry (WLSI).The distinctive features are defined as discontinuities, so that the fringe contrast function cannot be modeled as a singl
