摘要
目的凸曲线溜槽装置常用于轻质棒料的姿态变换,针对现有轻质棒料溜槽曲线设计缺乏理论指导,且曲线优劣无法量化评估,导致卡堵和物料损伤等问题,通过动力学分析和数值仿真,提出一种针对凸曲线溜槽的量化评估及优化方法,为凸曲线溜槽的设计和优化提供参考。方法以烟支这一典型轻质棒料为研究对象,基于ADAMS仿真软件建立物料与溜槽装置的动力学模型,对影响上述现象的关键因素进行分析。通过动力学分析物料在凸曲线溜槽上的运动行为,并基于关键影响因素提出评估及优化方法。结果通过优化溜槽曲线,有效解决了物料在接触竖直挡板前飞离溜槽的问题,使得物料离开溜槽的倾斜角由64.70°提高至70.20°,评估指标理论计算值由0.97提高至1.45,评估结果与仿真及实验结果接近。结论提出了一种针对凸曲线溜槽的量化评估及优化方法,基于该优化方法得到的优化曲线相对于原曲线,降低了物料损伤程度及卡堵风险。同时,仿真及实物测试验证了所提出评估方法的有效性,适用于实际场景。
The convex curved chute device is commonly used for the attitude transformation of lightweight rod materials.However,the current design of the chute curve for these materials lacks theoretical guidance,and its quality cannot be quantitatively assessed,leading to issues such as material blockage and damage.The work aims to propose a method for the quantitative evaluation and optimization of convex curved chutes through dynamic analysis and numerical simulation,so as to provide a solid reference for the design and optimization of such chutes.With cigarette rods,a typical lightweight rod material,as the research object,a dynamic model of the material and chute system was established with ADAMS simulation software.The key factors influencing the material behavior were analyzed.The dynamic motion of the material along the convex curved chute was studied,and based on these key factors,an evaluation and optimization method was developed.The optimized chute curve successfully addressed the issue of the material flying off the chute before reaching the vertical baffle.The departure angle of the material increased from 64.70°to 70.20°,and the theoretical value of the evaluation index improved from 0.97 to 1.45.These evaluation results aligned closely with both simulation and experimental outcomes,demonstrating a consistent trend.In conclusion,the proposed method for quantitative evaluation and optimization of convex curved chutes offers significant improvements.The optimized curve reduces material damage and minimizes the risk of blockage compared to the original design.Both simulation and physical testing validate the effectiveness of the proposed evaluation method,confirming its applicability in real-world scenarios.
