| 目的 针对特定型号导弹舱段与前滑块之间的螺栓连接结构在预紧力作用下可能遇到的冲击响应问题，对螺栓连接结构的耐冲击环境适应性进行研究。方法 首先，基于螺栓连接理论，计算出推荐的预紧力以及保证结构不发生破坏所需的最小预紧力值。然后，为了验证螺栓连接结构计算模型的准确性，采用有限元分析方法，并参照相关标准对模型进行校核。随后，对3种不同的前滑块与舱段螺栓连接结构施加预紧力的情况进行有限元模拟，找出最优的连接结构配置。最后，研究重点转向整个导弹与发射装置的结构系统。结果 螺栓连接的预紧力模型与试验值表现出了良好的一致性，证明了所选参数和模型的准确性。同时，螺栓配合螺母的连接方式在预紧力的作用下能够达到最小的应力水平，故选择其为滑块与舱段间的连接。另外，性能等级为12.9的螺栓可以满足垂向的冲击载荷。结论 通过对系统在预紧力的作用下施加垂向冲击进行响应分析，可以评估弹架组合下滑块螺栓连接结构在实际应用中的耐冲击环境适应性。该研究为该型号导弹的设计提供了科学依据，确保其在极端冲击环境下的可靠性和安全性，进而提升整体作战效能。 |

| The work aims to study the adaptability of the bolt connection structure to the impact environment, so as to solve the possible impact response issues between the specific model of the missile cabin section and the front slider under pre-tension. Firstly, based on the theory of bolted connections, the recommended preload and the minimum preload required ensuringthe structureintactness was calculated. Next, in order to verify the accuracy of the calculation model for bolted connection structures, the finite element analysis method was used, and the model was verified according to relevant standards. Subsequently, finite element simulations were conducted on the application of finite to three different front sliding blocks and cabin bolt connection structures, and the optimal connection structure configuration was found. Ultimately, the research focus shifted to the structural system of the entire missile and launch device. The results showed good consistency between the preload model of bolt and the experimental values, proving the accuracy of the selected parameters and model above mentioned. At the same time, the connection method of bolts and nuts could achieve the minimum stress level under the action of preload, so it was selected as the connection between the sliding blocks and the cabin section. In addition, bolts with a performance level of 12.9 could stand vertical impact loads. By analyzing the response of the system to vertical impact under preload, the adaptability of the sliding blocks connection structure under the combination of the spring frame to the impact environment in practical applications could be evaluated. This study provides a scientific basis for the design of this type of missiles, ensuring its reliability and safety in extreme impact environments, thereby improving overall combat effectiveness. |
