; 文章编号:1672-7207(2015)06-2027-09 Mechanisms of rail grinding patterns based on standard rail profile ZHI Shaodan, LI Jianyong, CAI Yonglin, SHEN Haikuo, NIE Meng (School of Mechanical & Electronic Control Engineering, Beijing Jiaotong University, Beijing 100044, China) Abstract: The grinding patterns have direct effects on the rail grinding processes and the ground results. It’s......
J. Cent. South Univ. (2018) 25: 230-240 DOI: https://doi.org/10.1007/s11771-018-3732-9 A prediction method of rail grinding profile using non-uniform rational B-spline curves and Kriging model YANG... a prediction method of the rail grinding profile for a grinding train. As a worn rail profile is a free-form curve, the parameterized model of a rail profile is constructed by using the cubic NURBS curve. Taking......
