摘要
针对振动盘料斗设计时因参数选择不准确而导致能耗过高的情况,分析了振动盘振动给料过程中物料的受力情况并建立了数学模型,得到了物料相对料斗静止、向前滑移、向后滑移和跳跃所需的临界加速度。通过减小物料向前滑移所需的临界加速度来降低功耗,建立了以物料相对料斗向前滑移所需的临界加速度极小化为目标函数、以料道螺旋升角α和振动升角β为设计变量的优化设计数学模型。利用该数学模型对现有的1台振动盘料斗进行参数优化,优化后物料向前滑移所需的临界加速度减小了12.2%,取得了良好的优化效果,为后续设计提供了理论指导。
In response to the high energy consumption caused by the inaccurate selection of parameters in the design of the vibrating disc hopper, the force of the material during the vibrating feeding process of the vibrating disc was analyzed and a mathematical model was established to obtain the critical acceleration required for the material to come to rest, slide forward, slide backward and jump relative to the hopper. By reducing the critical acceleration required for the material to slide forward to reduce the power consumption, an optimized design mathematical model is established with the minimization of the critical acceleration required for the material to slide forward relative to the hopper as the objective function and the spiral lift angle α and vibration lift angle β as the design variables. The optimization model was used to optimize the parameters of an existing vibrating disc hopper, and the critical acceleration required for the material to slide forward was reduced by 12.2% after the optimization, which achieved a good optimization effect and provided theoretical guidance for the subsequent design.
