Welding temperature nearby weld seam is above the critical temperature of the quenching and tempering of high tensile strength steel(HTS)during HTS structure welding process.
Traditional bogie frame fatigue design uses the amplitude loads,which are significantly not inconsistent with random excitation suffered on the frame in actual operation.
Master S-N method of welded structure fatigue life prediction system,which is based on the calculation formula of ASME standard,the development of special-purpose software,The key is to use insensitiv
In this study the medium carbon railway axle steel was gas nitrocarburized and the fatigue properties of the untreated and treated specimens were investigated by the axial loading fatigue tests.
Polar molecules coated core-shell particles have been used to prepare electrorheological(ER)fluids with high performance. Inspired by those studies, TiO2/urea core-shell structured particles were fabr
