皮带传动起毛机的动力性能建模

通过分析起毛机工作针辊受力情况，依据阶梯轴弯曲变形理论，建立了起毛机单针辊力学模型；结合针辊之间皮带受力分析，进而建立了针辊系统力学模型。在对起毛阻力及其分布规律进行一定近似假设的基础上，提出了起毛阻力模型，从而推导出电机功率与最大起毛力矩关系模型。讨论了锡林电机、顺针辊电机和逆针辊电机功率对最大起毛力矩的影响。以某型号36辊起毛机为例，说明了模型的实用性。

Modeling of dynamic performance for belting raising machine

By analyzing the mechanical status of the working pile rollers on raising machine, the mechanical model of single pile roller is established according to stepped beam deformation theory. And then the mechanical model of pile roller is set up together with the analysis of loads on belts between pile rollers. On the basis of the hypothesis of raising resistance and its distribution, the raising torque model is proposed and furthermore the relation model of electromotor power and the maximum raising torque is deduced. Additionally, this paper involved in the influence of power on maximum raising torque in drum electromotor, pile roller electromotor and counter pile roller electromotor. Finally, taking a certain raising machine with 36 rollers as an example, the practicability of such analysis model is demonstrated.
