The structural and phase transformations occurring in the near-surface layers of pre-quenched high-speed steel subjected to pulsed electron beam melting have been investigated.
After making two passes down the walkway at their preferred speed, subjects were asked to walk with a bent-knee, bent-hip (BKBH) gait at their preferred speed.
For the measurement of walking speed, subjects were instructed to walk 10 m two times at their usual speed.
At each speed, subjects had one minute of practice and then data were collected for one minute.
For habitual gait speed, subjects were asked to walk at their own normal, comfortable speed, and were reminded that this was not a test of their fastest walking speed.
This paper compares the performance of EARSM, SAS and IDDES turbulence models for the aerodynamic problem of a high-speed train subjected to crosswind.
The dynamic responses of a European high-speed railway subjected to a harmonic moving load are calculated as an example for demonstration and discussion.
(2) Aiming at the high-speed train subjected to cross winds, the dynamic test using indirect method for wheel rail force measurement was conducted.
Aiming at the high-speed train subjected to cross winds, a dynamic test using indirect method for wheel rail force measurement was conducted in the Lanzhou-Xinjiang high-speed railway line.
For instance, the hunting motions of railway vehicles caused by the wear of wheel and rail profiles may lead to safety problems; a high-speed train subjected to strong cross winds has the potential risk of overturning.
