Influence on Armature Mechanical Property of Drive Coil Structural Parameter

To study drive coil structural parameter on armature mechanical property,base on circuit-electromagnetism theory,established model of three-dimensional coil gun through software Ansys and analysised influence on armature mechanical property owing to drive coil structural parameter.Simulation results indicate that the of coil section minish,length of coil section and coil rings increase,the force of armature increase,but the amplify is not big.Only the coil layers increase,the force of armature increase more.But considerating coil making,drive coil section is 0.5 mm×10 mm,rings number is 10,layers number is 11.It supplys vestiges of design coil gun further.
