双质体自同步振动输送机的物料运动分析

通过分析基于物料滑移理论的自同步振动输送机物料运动过程,在分段建立并求解输送机和物料的动力学微分方程的基础上,得出输送机和物料的稳态响应,数值分析输送机的工作频率、物料质量、摩擦系数和振动方向角对物料稳态运动时的速度和位移的影响,并进行数值仿真验证.结果表明：物料在水平方向的单向滑动加速度与输送机加速度呈线性关系.物料质量的变化对物料运动没有影响.随着输送机工作频率减小,物料的正向和反向滑动速度都增大,但反向滑动位移也增大;随着摩擦系数增大,物料的平均速度、滑动位移和反向滑动时间都增大;物料的平均速度、滑动位移以及正向滑动时间都随振动方向角的增大而增大....

Summary:通过分析基于物料滑移理论的自同步振动输送机物料运动过程,在分段建立并求解输送机和物料的动力学微分方程的基础上,得出输送机和物料的稳态响应,数值分析输送机的工作频率、物料质量、摩擦系数和振动方向角对物料稳态运动时的速度和位移的影响,并进行数值仿真验证.结果表明：物料在水平方向的单向滑动加速度与输送机加速度呈线性关系.物料质量的变化对物料运动没有影响.随着输送机工作频率减小,物料的正向和反向滑动速度都增大,但反向滑动位移也增大;随着摩擦系数增大,物料的平均速度、滑动位移和反向滑动时间都增大;物料的平均速度、滑动位移以及正向滑动时间都随振动方向角的增大而增大.
Bibliography:Through analyzing the material movement process of the self-synchronization vibration conveyer for dual-mass based on the material slippage theory, the movement of conveyer and material stationary response were obtained on the basis of subsection establishing and solving the dynamic differential equation. The influence of conveyer frequency, material mass, friction coefficient and vibrating direction angle on the speed and displacement of material movement were discussed by numeric analysis, then the results were verified by the numerical simulation. The result shows that there exists linear relation between slip acceleration of material and vibration conveyer in single horizontal direction. The material mass has no effect on material movement. The material transportation speed and displacement of reverse slide will increase with decreasing of the conveyer frequency. As the friction coefficient increases, the material transportation displacement, time of reverse slide and average speed will increase. The mate
