摘要
目的通过分析纸塑复合袋成型工艺,针对纸塑复合袋生产中存在位置偏移和倾斜的缺陷,明确复合袋生产中需要纠偏的需求。方法建立复合袋的有限元模型,以薄板屈曲理论为基础,运用Ansys Workbench中的屈曲分析工具对各种姿态下的纸塑复合袋进行仿真,求解皮带最大屈曲载荷,最后根据最大屈曲载荷等于复合袋所受的摩擦力这一条件,得到皮带所受的最大正压力。结果当皮带间距为50 cm时,最大皮带正压力最大,即纸塑复合袋能够承受的摩擦力最大,纠偏时的轨迹与理论轨迹误差更小。结论该计算结果准确,数据充足,满足纠偏中正压力的控制需求。
By analyzing the forming process of paper-plastic composite bags,the paper clarifies the demand for correction in the production of composite bags from the defects of positional deviation and tilt in the production of paper-plastic composite bags.And it is necessary to prevent the paper-plastic composite bag from wrinkling due to improper belt pressure during the correction process.The paper establishes the finite element model of the compo-site bag based on the theory of thin plate buckling,use the buckling analysis tool in Ansys Workbench to simulate the paper-plastic composite bag in various postures,and solve the maximum buckling load of the belt.Finally,the maxi-mum positive pressure to the belt can be obtainedaccording to the maximum buckling load equal to the composite.When the belt spacing is 50 cm,the maximum belt positive pressure is the largest,that is,the paper plastic compo-site bag can bear the maximum friction,and the error between the trajectory and the theoretical trajectory is smaller.The calculation result is accurate and the data is sufficient to meet the control requirements of positive pressure in correction.
