Autor: Zhang Zhiwen, Yang Xiaoying, Xue Yujun, Gong Limin, Li Junxing

Publikováno v: IEEE Access, Vol 8, Pp 105728-105743 (2020)

In this paper, we seek to evaluate supply chain logistics information quality (SCLIQ) from the Just-In-Time (JIT) perspective. First, based on the analysis of SCLIQ, it is proposed that the SCLIQ evaluation should be combined with JIT philosophy. Sec

Analysis of the Vibration Characteristic of Rolling Bearing-Rotor System of Machine Tool Spindle

Autor: Si Zhanfeng, Ma Wei, Li Jishun, Xue Yujun, Yang Fang

Publikováno v: Jixie chuandong, Vol 39, Pp 121-125 (2015)

The non- linear bearing force in the working state of the rolling bearing is deduced and non-linear dynamics equations of a system are established. The system axis path chart,the bifurcation diagram and the Poincare figure are drawn in Matlab and use
