At present, methods are usually adopted to simplify the system of the launching load and the load-relieving structure into a linear system to deal with the problem of Projectile-loaded Equipments against high overload; the results are not satisfactory as compared with the test results. According to the actual launching load and the nonlinear characteristics of load-relieving structure materials, based on a one-dimensional dynamical model in the strong shock condition, the load curve and the force-displacement curve of the load-relieving structure using material's mechanical experiment are obtained by curve fitting from data obtained by numerical simulations. The computational models of relative displacement and relative acceleration of the projectile-based equipment can be calculated using a precise integration method. With a certain special type shell as an example, the dynamic response of the projectile-based equipment is calculated, experiment results have verified the calculation results, and therefore, the research methods can provide a theoretical reference for the design of projectile-based equipment against high overload., authors=null, authorsList=null, authorCompany=null, correspAuthors=null,

articleAbstract=弹载器件的抗高过载设计是新型信息化弹药设计中的一大难点，也是制约各国信息化炮弹快速发展的主要瓶颈之一。目前，弹载器件抗高过载机制的研究主要采用将火炮发射载荷和减载结构简化为线性系统的方法，其研究结论与实弹试验结果存在较大差异。本文针对火炮实际发射载荷和减载结构材料的非线性特性，在建立强冲击条件下弹载器件一维动力学模型的基础上，通过数值拟合方法分别对外界载荷曲线和材料性能实验测得的减载结构材料力-位移曲线进行拟合，然后采用精细积分法递推出弹载器件的相对位移和相对加速度计算模型，并以某型特种弹为例，对其弹载器件的动态响应进行仿真计算，实弹试验验证了计算结果的合理性，文中有关研究方法可为各类弹载器件的抗高过载设计提供理论参考和方法依据。,
