在通过实验验证数值方法计算舱室内爆载荷及结构在冲击载荷作用下响应可靠性的基础上,以舱室典型加筋板优化后的夹层板为对象,采用非线性数值方法计算在不同位置敷设超弹性材料及相同面密度橡胶夹层板在内爆载荷作用下的位移、速度及加速度响应,并对夹层板吸能进行探讨。从计算结果可知:填充超弹性材料可有效减小舱室内爆载荷作用下夹层板的响应振荡峰值;面板敷设超弹性材料可更好地提高夹层板的抗爆性能;橡胶层会延长夹层板的响应周期,随橡胶层厚度的增加,夹层板响应周期更加持久,面板与背板的加速度差逐渐减小。
Based on the calculation of the internal explosive load and the response reliability of the structure under the impact loads by the experimental verification of the numerical method, the sandwich plate optimized by the typical stiffened panel in the cabin is taken as the object. By using the non-linear numerical method, The displacement, velocity and acceleration response of the elastic material and the same surface density rubber sandwich plate under the implosion load were discussed. The energy absorption of the sandwich plate was also discussed. From the calculation results, it can be seen that the superelastic material can effectively reduce the peak value of the response vibration of the sandwich plate under the cabin internal explosive load. The super elastic material can improve the antiknock performance of the sandwich plate. The rubber layer can prolong the vibration of the sandwich plate Response period, with the rubber layer thickness increases, the sandwich plate more durable response period, the acceleration difference between the panel and the backplane decreases gradually.
