The Variation of the Friction Coefficient in Pipe Connections Working Under Static and Dynamic Loads
Galling Time Dependent Friction Coefficient Lubrication
2009/10/14
The friction coecient and the galling process in metal to metal parts depend on many variables such as normal load, lubricant, roughness and design of the friction surfaces. Since developing a mathem...
Investigation of the Friction Coefficient in Smooth Open Channel Flows
Open channel energy loss friction factor
2009/10/14
In practical engineering, the friction coecient formulations developed for circular pipes are usually assumed to be valid for open channels and used in derivation of mathematical formulation. However...

The zinc-aluminum based ZA-27 alloy was produced by permanent mould casting. Using this alloy and bronze obtained from commercial sources, thin wall journal bearings were manufactured by machining. Th...
滚动轴承摩擦力矩的非线性特征（Nonlinear Characteristic of Rolling Element Bearing Friction Torque）
滚动轴承 摩擦力矩 时间序列
2009/5/22
以混沌理论为基础，通过试验研究滚动轴承摩擦力矩时间序列的非线性特征评估问题，为精确计算滚动轴承摩擦力矩的动态性能奠定基础。用关联维数标准差刻画摩擦力矩的不确定性，用关联维数均值描述摩擦力矩非线性特征的演变历程。研究表明，滚动轴承属于确定的非线性动力学系统，但其摩擦力矩呈现出明显的不确定性。随着转速的增加，滚动轴承摩擦力矩关联维数标准差与均值都呈现出非线性增大的趋势。
