| 目的 为了有效降低冲击能量对仪器带来的损伤，从而对内部装置进行有效的保护。方法 在薄壁金属管内填充倾斜功能金属材料，并对其进行仿真试验。随后基于能量吸收缓冲原理，并分析传统吸能装置，以提出新的能量吸收缓冲方案。结果 相较于传统缓冲吸能结构，新复合结构的吸能性能平均增幅为4.67%。利用数值模拟计算，并结合试验对比论证了方案的技术可行性。结论 提出的新型填充结构在能量吸收方面有明显效果，基本上达到了预期要求。 |
| 英文摘要: |
| The paper aims to effectively reduce the damage of instrument caused by the impact energy to protect the internal device effectively. Tilt functional metal materials were filled in thin-walled metal tubes and simulated. Then, based on the energy absorption and buffering principles, the traditional energy absorption devices were analyzed, and a new energy absorption and buffering scheme was proposed. Compared with the traditional energy absorption structure, the energy absorption performance of the new composite structure was increased by an average of 4.67%. The technical feasibility of the scheme was demonstrated by numerical simulation and experimental comparison. The new filling structure proposed in this paper has obvious effect on energy absorption. It basically meets the expected requirements. |
