摘要
目的在总结现有包装动力学研究成果及不足的基础上,为包装设计及改进提出进一步的研究方向及相应措施。方法从我军弹药包装历史与现代发展中所遇问题入手,主要阐述近年来有关弹药包装动力学的模型构建、相关试验测试、数值分析方法等研究以及存在的不足。结果现有包装的动力学模型构建大都基于线弹性、小变形假设,与复杂的实际情况存在一定偏差。针对包装设计可靠性的试验所需模拟信号要进行一定的调整方能使用,而不能单纯依靠标准所提供的试验谱形。另外,虚拟激励法在其动力学响应分析上能够取得较好的分析结果。结论弹药包装的设计研究仍存在一定的问题,且对内部包装,尤其是新型弹药的防护需要进一步加强。
The work aims to put forward the further research direction and relevant measures for the package design and improvement based on the summary of the existing research results and deficiencies of the package dynamics. Starting with the problems encountered in the history and modern development of the ammunition packaging in our army, the establishment of dynamic models, relevant tests, numerical analysis methods of relevant ammunition packages and the deficiencies in recent years were mainly elaborated. Most of the dynamic models of the existing packages were established based on the hypothesis of linear elasticity and small deformation, which resulted in certain deviation from the complicated reality. Moreover, the analog signals required by the test for package design reliability should be used after certain adjustment. However, the spectrum form simply provided according to the standards could not be relied on. In addition, the employment of pseudo-excitation method in its dynamic response analysis could obtain better analytical results. There are still so many problems remaining to be solved, especially in the protection for the inner package of a new type of ammunition.
