Autor: Xiang-dong Chang, Yu-xing Peng, Zhen-cai Zhu, Da-gang Wang, Xian-sheng Gong, Sheng-yong Zou, Shi-sheng Sun, Wen-xue Xu

Publikováno v: Advances in Mechanical Engineering, Vol 8 (2016)

The friction and wear behavior exists in ultra-deep coal mine between multi-layer winding hoisting ropes, and it decreases the rope’s service life directly, which threatens the safety coal mine hoist. In order to obtain the tribological properties

Molecular Dynamics Simulation of Effects of Stretching and Compressing on Thermal Conductivity of Aligned Silicon Oxygen Chains*

Autor: Wen-Xue Xu, Xin-Gang Liang

Publikováno v: Chinese Physics Letters. 37:046601

The effects of stretching and compressing on the thermal conductivity (TC) of silicon oxygen chain are studied by means of non-equilibrium molecular dynamics simulation. It is found that stretching can improve TC, and compressing may reduce the TC an

FSI simulation and experimental validation of nonlinear dynamic characteristics of a gas-pressurized hydraulic shock absorber

Autor: Ping-Zhang Zhou, Wen-Xue Xu, Zhen-Hua Lü

Publikováno v: IOP Conference Series: Materials Science and Engineering. 576:012014

The structure, fluid and gas dynamic models of a gas-pressured hydraulic shock absorber are established to form a 3-D FSI (Fluid-Structure Interaction) simulation model, which can be used to predict the working characteristics and kinematical respons

Segmentation approach for terrestrial point clouds based on the integration of graph theory and region growing

Autor: Tao Jiang, Zhi-zhong Kang, Wen-xue Xu

Publikováno v: 2009 Joint Urban Remote Sensing Event.

In view of the disadvantage of region growing in the point clouds segmentation, this paper proposes a novel segmentation method for TLS data by integrating graph theory and region growing. This method can be divided into four steps: (1) According to
