The interface between metallurgy and mechanics in material performance by M. Newby, M. N. James

“…The interface has particular importance in circumstances where environmental influences have a key role in determining performance characteristics (e.g. creep, environmentally-assisted cracking, or corrosion), where performance is dominated by fatigue or fracture, where welding is used to join components, or where tribology plays a role. The paper focuses on the problems associated with cracking and uses case study examples drawn from engineering practice to illustrate the role of metallurgical factors in mechanical performance of materials.…”

STUDY ON STEADY-STATE TEMPERATURE FIELD OF THE MESHING PAIR OF TWO-TOOTH DIFFERENCE SWING-ROD MOVABLE TOOTH DRIVE by YI YaLi, JI YaMeng, GUO Hui, JIN HeRong

“…Based on the basic theory of heat transfer and tribology,the calculation formulas of the friction heat flux density of meshing pair,the meshing tooth surface and the end face convective heat transfer coefficient with two-tooth difference swing-rod movable tooth drive are derived under the slip condition.A finite element model of the thermal analysis of the gear meshing pair is established,and the steady-state temperature field of the meshing pair under thermal balance state is calculated and analyzed by using the ANSYS finite element software.Combined with numerical simulation results,the influence of tooth profile design parameters on the temperature field is revealed.The result shows that:the steady-state temperature field of the meshing pair is determined collectively by the heat flux of the contact zone and the convection heat transfer coefficient of each surface.Because the temperature rise of sliding friction is larger,the maximum temperature appears in the center of the gear meshing face width of the center,the radius of the base circle radius has a great influence on the body temperature of the meshing surface,and the swing rod length is less affected.The research results lay the foundation for the study of the thermal deformation and thermal mechanical coupling characteristics of the meshing pair,so as to guide the dynamic design of the two-tooth difference swing-rod movable tooth drive.…”

Experimental Analysis on Friction Characteristics of MW Wind Turbine Generator Yaw Braking System by Ming LIU, Xuebing YANG, Xuewen ZHANG, Zhenrong HUANG, Zhongjie BU

“…[Method] Based on the friction test bench of disc brakes, this paper simulated the operation of the brakes under different working conditions of the WTG, studied the friction characteristics of organic composite materials under different pressures, velocities and temperatures for dual components of same and different materials, and revealed the influencing factors of different parameters on friction coefficient from the perspective of tribology. [Result] The results show that under the same surface parameters, different dual component materials have a significant impact on the friction coefficient; The friction coefficient decreases with the increase of braking pressure and relative velocity of the friction pair and the braking pressure has a greater impact factor on the friction coefficient; The friction coefficient is greatly affected by temperature, and the higher the temperature between the friction pairs, the smaller the friction coefficient. …”
