J. Cent. South Univ. (2018) 25: 936-948 DOI: https://doi.org/10.1007/s11771-018-3795-7 Method for secondary spring load equalization of railway vehicles with two-stage spring suspension: Modeling... is quite complex. Therefore, an effective and reliable method in application is developed in this paper. Firstly, the best regulation of spring load is solved based on a mechanical model......

School of Civil Engineering, Hebei Engineering University...> Abstract: Under impact load, using energy estimation and updated finite element method, the crack propagation of Mg-Li alloys was studied, and the relations between high speed impact, time interval......
J. Cent. South Univ. Technol. (2011) 18: 1184-1192 DOI: 10.1007/s11771-011-0821-4 Forecasting model of residential load based on general regression neural network and PSO-Bayes least squares... University Press and Springer-Verlag Berlin Heidelberg 2011 Abstract: Firstly, general regression neural network (GRNN) was used for variable selection of key influencing factors of residential load......
indicates that the failure of SiC particles has important effect on the yield stress of the SiC reinforced aluminum alloy composites. Key words: SiC/Al composites; yield stress; load transferring......
structures, fabrication defects such as pores and local delaminations can be easily formed in the intersection zone which significantly affect the load bearing capacity. In this work, the mechanical behavior of C/SiC T-section under pulling load was investigated, and especially the delamination behavior was studied by introducing the cohesive zone model into the finite element modeling. It was found......
J. Cent. South Univ. (2017) 24: 1754-1761 DOI: https://doi.org/10.1007/s11771-017-3583-9 Effect of applied load on transition behavior of wear mechanism in Cu-15Ni-8Sn alloy under oil lubrication... was investigated on a ring-on-block tester in oil lubrication. The results showed that the wear rate increased slowly from 1.7×10-7 to 9.8×10-7 mm3/mm under the load lower than 300 N......
