以理想状态下大型导弹外壳板(简称弹壳板)与对称式三轧辊滚弯机(简称三辊机)中三轧辊之间弹塑性力学关系为基础,研究实际工况下弹壳板产生滚弯直线度误差的根源,并推导出一组可确定“改进型”轧辊半径的方程组. 研究表明,以计算该方程组所求得的“改进型”轧辊替代原三辊机的轧辊可使弹壳板滚弯直线度误差显著减小.
Based on the elasto-plastic mechanics relationship between the three rolls in the ideal missile shell plate (referred to as the shell plate) and the symmetrical three-roll bending machine (referred to as the three-roller machine), the roll-bending straight line Degree of error and derive a set of equations to determine the “improved” roll radius.The study shows that the “improved” roll obtained by the calculation of this equation can replace the roll of the original three-roll machine can make the shell plate Roll straightness error is significantly reduced.
