摘要
以FMFQ10×2型磨粉机长为1 000 mm、直径为250 mm的快辊为研究对象,首先建立了磨辊的力学模型,并进行了磨辊运动学参数及负载时的受力分析与计算;随后采用Ansys Workbench的瞬态动力学模块,对磨辊以工作转速为550 r/min,所受辊间压力为最大时进行瞬态响应分析,分别得出了磨辊速度、加速度、位移及磨辊各个轴段和辊体的等效应力随时间的响应云图及曲线,并将仿真的结果与理论计算做了比较,得出仿真结果与理论计算相一致,为磨辊结构动力学分析及其结构的改进提供理论基础。
： In this paper, a rapid roll with a length of 1 000 mm and a diameter of 250 mm is used as the research object. The mechanical model of the roller is established first. The kinematic parameters of the roller and the force analysis and calculation are carried out. The transient response of Ansys Workbench was used to analyze the transient response of the roller with the working speed of 550 r/min and the maximum pressure between the rollers. The speed, acceleration, displacement and roller and the simulation results are in agreement with the theoretical calculation. The simulation results are in agreement with the theoretical calculation, which is the dynamic analysis of the roller structure and its structure. The simulation results are in agreement with the theoreti- cal calculation. To provide a theoretical basis for improvement.
