Thermohydrodynamic lubrication analysis of misaligned journal bearing considering the axial movement of journal
Biao Li,Jun Sun,Shaoyu Zhu,Yangyang Fu,Xiaoyong Zhao,Hu Wang,Qin Teng,Yanping Ren,Yunqiang Li,Guixiang Zhu +9 more
TL;DR: In this paper, a numerical model for the thermohydrodynamic lubrication of bearing considering the axial movement of journal is established, and based on which a comprehensive analysis on the performance of misaligned journal bearing is conducted by solving the generalized Reynolds equation, heat conduction equation and energy equation.
Journal ArticleDOI
Stochastic models for turbulent lubrication of bearing with rough surfaces
TL;DR: In this article, the stochastic turbulent lubrication models of one-dimensional longitudinal rough surface, transverse rough surface and isotropic rough surface were derived for journal bearing and thrust bearing, and the results were in good agreement with the corresponding experimental data.
Journal ArticleDOI
On the lubrication characteristics of piston ring under different engine operation conditions
Jun Sun,Xiao Zhang,Jianxiong Zhu,Yaming Gao,Hu Wang,Xiaoyong Zhao,Qin Teng,Yanping Ren,Guixiang Zhu +8 more
TL;DR: In this paper, the performance analysis of a four-stroke engine under different engine operating conditions is done, in which the lubricating oil at the inlet of piston ring is considered as the lube attached on the relevant location of cylinder wall after the piston ring moves over at the previous stroke.
Journal ArticleDOI
Dynamic response characteristics and damage mechanism of impact wear for deep plasma nitrided layer
Yanping Ren,Pengfei Wang,Zhen-bing Cai,Ji-fu He,Jinsheng Lu,Jinfang Peng,Xiaojun Xu,Minhao Zhu +7 more
TL;DR: In this paper , the impact wear behavior of deep plasma nitrided layer and its substrate (axle steel) were investigated, and it was shown that the plated material showed a lower energy absorption ratio and better impact resistance than the untreated material.
Journal ArticleDOI
Research on Turbulent Lubrication of Misaligned Journal Bearing Considering the Axial Motion of Journal
TL;DR: In this paper, the authors derived the generalized turbulent lubrication equation considering the axial motion of the journal and used the finite-difference method to solve the generalization of the equation.
