R. China;2.Jiangxi University of Science and Technology, Ganzhou 341000) 摘要:This paper studies the elastic sag resistance of new low-carbon martensite spring steel 35Si2CrVB developed recently......
Spring constitutive model of rigid pile composite foundation and application in design of raft foundationHAN Xiao-lei(韩小雷)1,2, XIAO Cheng-an(肖成安)1,2, LI Jia-xuan(李稼轩)1, FENG Jie-qiang(冯杰强)1(1. School... to the differential settlement of the foundation is neglected, which leads to larger support moments and longitudinal bending of raft compared with real values. The spring constitutive relation of composite......
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..., the secondary spring loads of railway vehicles must be well equalized. Due to the coupling interactive effects of these hyper static suspended structures, the equalization adjustment through shimming procedure......
