J. Cent. South Univ. (2019) 26: 2318-2327 DOI: https://doi.org/10.1007/s11771-019-4176-6 Investigation of weld parameters on ductility, onion ring and fracture behaviour of friction stir welded...: Friction stir welding provides better retention of ductility and plasticity in comparison to fusion welding and it increases the stability against cracking. This study aims to enhance both the ductility......

Friction and Wear Property of Cu-Cr Alloy刘建华,王玉辉,高红,张瑞军摘 要:The friction and wear behaviors of the Cu-Cr alloy sliding against GCr15 steel at different... weight increases, by comparison, the biggest friction coefficient of Cu-Cr alloy was obtained at load 100 N and rotate speed at 100 r·min-1 friction condition. Moreover, the dominant wear forms......
J. Cent. South Univ. (2017) 24: 71-80 DOI: 10.1007/s11771-017-3410-3 Thermo-structural analysis on evaluating effects of friction and transient heat transfer on performance of gears in high... for finding the change in mechanical properties. The friction on the contact surface is another important parameter in interaction of the gear with the shaft. Evaluating the gear stress and deformation......

Internal Friction in Rail Waist of BNb and BNbRE Steels Yu Ning1,Ren Xinjian2,Sun Zhenyan1,Ji Jingwen1,WANG Yunsheng2 (1.College of Sciences, Northeastern University, Shenyang 110004, China.... The results of the internal friction measured during ascending and descending temperature under 700 ℃ show that there is a high temperature damping which can be completely disappeared during descending......
was used to validate the correctness of the model. Then, the friction coefficient function was fitted with the test data to get the friction coefficient model suitable for this paper. Finally, based on the evaluating index of the friction torque and the friction power, two groups of design parameters (oil pressure and friction coefficient) were simulated and explained the changing regulation......
