Lightweight design and research of uncoiler for FSL1600 high speed aluminum foil shearing machine

以某国产铝箔剪切机组FLS1600为研究对象,对其动力侧和操作侧进行了ABAQUS有限元分析,得到动力侧最大等效应力为196 MPa,最大变形量为8.1~10.0 mm,符合使用要求。根据应力应变云图,确定优化设计的关键零部件区域,利用拓扑优化原理,将圆孔处强度和整体质量作为目标函数进行优化计算,设计新的结构。新产品最大应力为94.7 MPa,最大变形量为16.8 mm,均符合生产要求,且动力侧质量为904 kg,降低了近70%,操作侧质量为602 kg,降低了接近80%,取得了显著的减重效果。

This paper takes the aluminum foil cutting,FLS1600 produced by a domestic factory as the research object,and conducts ABAQUS finite element analysis on the power side and the operation side.The maximum equivalent stress on the power side is 196 MPa,and the maximum deformation is between 8.1 and 10.Omm,which meets the use requirements.Based on this,the key component areas for optimal design are determined.Using the topological optimization principle,the strength and overall mass at the circular hole are optimized as objective functions to design a new power side structure.The maximum stress of the new product is 94.7 MPa,and the maximum deformation is 16.8 mm,which meets the production requirements.The mass of the new product is 904 kg,reducing by nearly 70%.On the operating side,the mass is 602 kg,reducing by nearly 80%.
