Abstract  By comparing the CEMA method for power and tension calculations of belt conveyor with the DIN2201 method, the characteristics of the CEMA method was definitely analyzed. The power and tension calculation software for belt conveyor was developed according to the CEMA method developed by Visual Basic 6.0 and it was validated by case studies and engineering applications. Through research on the relationship between curve resistance factor Ky in the CEMA method and analog friction factor f in the German DIN2201 standard, the regularity of the main resistance in the CEMA method was obtained and the correction function of analog friction factor was provided; with the correcting skills of temperature correction factor; the power and the tension could be calculated according to the input analog friction factor, which extended the functions of this software. Due to the fact that there was no correction method relative to temperature when adopting DIN22101 standard, the corrected value of analog friction factor under low temperatures was calculated by the CEMA method．

Key words： belt conveyor      power and tension calculation      main resistance      temperature correction

带式输送机功率计算方法及其工程应用问题的研究

通过CEMA带式输送机功率和张力计算方法与德国标准DIN22101计算方法的比较分析，明确了CEMA方法的特点，以Visual Basic 6.0为开发工具开发了CEMA计算方法的带式输送机功率张力计算软件，通过实例和工程应用验证了软件的正确性．通过研究CEMA算法中弯曲阻力系数 Ky 和DIN22101标准中模拟摩擦系数 f 的关系，得出CEMA算法主要阻力的规律；给出了设定模拟摩擦系数修正功能，采用温度校正系数的修正技巧使软件能够按输入的模拟摩擦系数进行功率和张力计算，扩展了软件的功能．针对应用DIN22101标准时没有与温度相关的修正方法，利用CEMA算法得出模拟摩擦系数在低温情况下的修正值．
