破碎机齿冠内温度及热应力分布研究

Analyses on the Temperature and Heat Stress Distributions of the Crown of Crusher

在现场测量了破碎机破碎烧结矿时其齿冠的表面温度和环境温度。利用软件ANSYS计算出破碎机齿冠内温度与热应力的分布 ,分析了齿冠内温度与热应力分布的规律。得出了结论 :由温度变化引起的齿冠热应力值很小 ,在进行齿冠材料设计时可以不考虑热应力的影响。

The surface and ambient temperatures of the crown of crusher in crushing sintering ore were measured in situ. Based on the measured results, the working temperature and heat stress of the crown were calculated and the distribution patterns of them were analyzed by use of ANSYS software. It was concluded that the heat stress due to the change of temperature was very low so the heat stress could not be considered for the material design of the crown.
