摘要
基于ANSYS有限元模拟平台,建立箔板电磁微成形有限元模型,开展阵列通道电磁微成形过程的有限元模拟分析,获得均匀压力线圈电磁力分布规律及箔板电磁微成形过程中零件不同区域典型点动态响应过程.模拟结果显示,电磁微成形过程中均匀压力线圈能够为金属箔板变形区域提供始终保持均匀的电磁力作用,在成形过程中零件不同区域典型点与模具表面高速碰撞后发生不同程度的弹复运动.使用内凹型和外凸型两种形式模具,开展阵列通道电磁微成形实验,微通道高度充填比分别达到93%和100%,微通道最大充填相对误差分别为0.014 8和0.019 6.结果表明,电磁微成形技术能够成形出一致性好的阵列微通道零件.
The finite element model of electromagnetic micro forming on metal foil was established based on the finite element simulation platform.The finite element simulation was performed on the array of micro channel formed by electromagnetic micro-forming.The distribution of magnetic stress of uniform stress coil and dynamic response process of typical points in different area were obtained in electromagnetic forming process.The simulation results show that the electromagnetic forming can provide uniform distribution stress on the deformation region.At the same time,various degrees of rebound phenomenon takes place on different typical dots on the component plane area after colliding with die surface.Electromagnetic micro-forming experiment was conducted on the array of micro channels by concave and convex mold.The filling ratio of the micro channels was 93%and 100%respectively.The relative error of filling ratio between micro channels was 0.014 8and 0.019 6respectively.Results show that array channel components with favorable consistency can be formed by the electromagnetic forming.
