摘要
目的分析螺旋瓦楞横切机剪裁瓦楞纸板产生的机械振动,并通过减振减小上、下刀轴振动响应,使其达到生产所需剪裁精度要求。方法对螺旋瓦楞横切机进行了动力学建模,通过数学解析和Ansys仿真软件分别进行振动分析。结果将解析结果与Ansys仿真结果进行对比,分析得到所建立的振动模型是正确的,通过分析横切机系统振动特性参数,提出降低振动响应方法,即采用碳纤维材料使上、下刀轴振动响应控制在0.07 mm范围内,使其达到横切机剪裁精度要求。结论建立的动力学数学解析模型和Ansys仿真对研究横切机振动特性,降低振动响应,改善横切机剪裁质量是有效的。
The work aims to analyze the mechanical vibration generated when the spiral corrugated flying shear machine is cutting corrugated board and to reach the cutting precision necessary for production by reducing the vibration response of upper and lower cutter shafts. The dynamics model of spiral corrugated flying shear machine was established. Vibration analysis was carried out by means of mathematical analysis and Ansys simulation software. By comparing the analytical results with the Ansys simulation results, they proved that the vibration model established was correct. Based on the analysis of vibration characteristic parameters of flying shear machine, the method used to reduce the vibration response was proposed, namely carbon fiber material was used to control the vibration response of upper and lower cutter shafts within 0.07 mm, so as to reach the cutting precision requirements of flying shear machine. All the above have proved that it is effective to study the vibration characteristics, reduce vibration response and improve cutting quality with the dynamic mathematical model and Ansys simulation.
