Method for equivalently evaluating buffer energy absorption performance of lattice structure for initiating explosive device

A lattice structure buffer energy absorption performance equivalent evaluation method for an initiating explosive device adopts a lattice structure buffer energy absorption performance evaluation method applied by a small subsample multi-rate equivalent load, comprehensively considers the mechanical behavior influence of a loading rate on a lattice structure, and calculates lattice structure calculation model parameters under different conditions through presetting the loading rate. And according to the lattice structure calculation model parameters, reversely deducing the characteristic parameters of the densification load and the maximum absorption energy at the current impact speed, and evaluating the buffer energy absorption performance of the lattice structure under the impact of the specified mass and speed according to the calculation result. 一种火工装置用点阵结构缓冲吸能性能等效评价方法，采用小子样多速率等效载荷施加的点阵结构缓冲吸能性能评价方法，综合考虑加载速率对点阵结构的力学行为影响，通过预设加载速率于不同情况下计算点阵结构计算模型参数，再根据点阵结构计算模型参数反推当前冲击速度下，基于致密化载荷和最大吸收能量特征参数，根据计算结果评价点阵结构在规定质量和
