摘　　要：研究了战术导弹飞行主动段力学环境预示的快速计算方法。首先根据类似型号外推方法得到新型号的发动机前裙的力学环境,再基于新型号的简单有限元模型可以获得指定的位置的力学环境。该方法简单、计算效率高,可用于型号研制初期,为力学环境试验条件制定提供参考。The fast calculation method of dynamic prediction for tactics missile in boost phase is investigated. Firstly, the mechanical environment of forward dome is derived from the similar model, and then the mechanical environment at the specified location can be calculated by simple beam-mass FEM model. The simple and efficient method can be used in the initial phase of the model development project to provide reference for the dynamic environmental conditions for the missile.
