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.
