Temperature field analysis on end-bearings with steel-backed copper plastic 3-layered composite material

利用传热学、摩擦学和有限元的基本原理,建立了具有摩擦生热的聚甲醛钢背铜塑3层复合材料端面轴承的二维稳态热传导数学模型。应用ANSYS软件分析了端面轴承的稳态温度场。通过改变载荷、转速和表层材料厚度计算了复合材料端面轴承的最高温度。结果表明,端面轴承最高温度随载荷、转速、表层材料厚度的增加而升高,为研究钢背铜塑多层复合材料热影响提供了参考依据。

Utilizing the basic principle of heat transfer, tribology and finite element, the mathematical model of two-dimensional steady stated heat conductance was established for end bearings with friction calorific polyformaldehyde steel backed copper plastic 3-lay- ered composite materials. The steady stated temperature field of end beating was analyzed by the ANSYS software. By means of changing the loading, rotary speed and thickness of the surface layer material the highest temperature of end bearing with composite materials was calculated. The result indicated that the highest temperature of end beating would rise along with the increase of thickness of surface layer materials, thus provided referential foundation for the study on the influences of steel backed copper plastic multi-layered composite materials.
