摘　　要：为了探索更高效率的缓冲材料,提高引信内部元件的可靠性,提出了将人工软骨仿生材料作为弹载缓冲材料,并使用马歇特锤试验装置,对人工软骨仿生材料垫片和传统缓冲垫片进行了测试。测试结果表明:人工软骨仿生材料具有很好的缓冲效果,在幅值约4万g,持续时间约100μs的加速度过载下,人工软骨仿生材料的缓冲效果比传统缓冲材料更好;随着厚度的增加,材料整体的缓冲能力增强,但单位厚度的材料体现的缓冲效果减弱。在多次重复试验时,人工软骨仿生材料的缓冲性能保持稳定,为引信内部缓冲材料的选择和设计提供一定的参考。In order to explore higher-efficiency cushioning materials to improve the reliability of the internal components of fuze,the artificial cartilage biomimetic material was proposed as the buffer material on the projectile,and both of the artificial cartilage biomimetic material gasket and the traditional buffer gasket was tested on Machete Hammer device.The results showed that,under the acceleration overload of amplitude about 40000 g and duration of about 100μs,the cushioning effect of artificial cartilage biomimetic materials was better than that of traditional cushioning material.As the thickness increased,the overall cushioning capacity of the material increased,but the cushioning effect of the material per unit thickness weakens.During repeated tests,the cushioning performance of the artificial cartilage biomimetic material remained stable,which provided a certain reference for the selection and design of the internal cushioning material of the fuze.
