防腐镀层对引信软带弯矩的影响

Influence of Anti-corrosion Coating on Fuze Unwinding Ribbon Bending Moment

针对传统引信软带弯矩计算公式并未考虑防腐镀层影响的问题,提出了基于塑性力学理论的镀后软带及其镀层弯矩的计算方法。该方法建立了防腐镀层材料和厚度与引信软带弯矩的计算公式,揭示了引信软带镀后弯矩变化机理。理论分析和仿真结果表明,对于同一种镀层材料,镀层厚度是影响引信软带弯矩的主要因素;对于同一镀层厚度,镀层材料的强度系数和应变强化指数是影响引信软带弯矩的主要因素;同一截面内的不同区域对弯矩所产生的影响是不同的。选用合适的镀层材料种类和厚度对于控制引信软带弯矩非常重要。

Aiming at the problem that the formula of bending of traditional fuze unwinding ribbon does not considered the influence of anti-corrosive coating,the calculation method of plating unwinding ribbon and its coating bending moment based on plastic mechanics theory was put forward.This method established the formula of the anti-corrosion coating material and the thickness and the bending moment of the fuze,and revealed the mechanism of the bending moment of the fuze.Theoretical analysis and simulation results show that the thickness of the coating was the main factor affecting the bending moment of the fuze unwinding ribbon for the same coating material;and the strength factor and the strain hardening exponent of the coating material were the main factors that affected the bending moment of the fuze unwinding ribbon for the same coating thickness;and the influence of different areas in the same cross section on the bending moment was different.It was very important to select the proper kind and thickness of the coating material to control the bending moment of the fuze unwinding ribbon.
