舰载导弹垂直发射时适配器动态特性研究

摘要

为研究舰载导弹发射时的适配器动态特性，应用有限元软件Abaqus建立含有适配器的舰载导弹垂直发射非线性结构动力学模型，并采用中心差分法进行发射过程的瞬态动力学计算；计算结果揭示发射过程中适配器的应力变化、所受摩擦力变化规律及适配器厚度变化规律，为舰载导弹垂直发射箱中适配器的设计提供设计依据。%In order to analyze mechanical characteristics of a missile adapter for some vertical missile launching system, aimed at hyperelastic spong material of adapter, mechanical model is got according to experimental data. By using ABAQUS, the nonlinear dynamic model of that vertical launch system which contains adapter is established based on reasonable simplification. The transient dynamics calculation of vertical launching process is carried out by use of central finite difference method and the results reveal the rule of adapter friction and adapter's thickness variation in the process of launching. The structural dynamics model presented here possesses an important reference value and guidance to intensity checkout and structure optimization of adapter.
