建立了航行体水下水下发射刚体动力学计算模型，计算提取了水下发射过程贮运筒的受力。采用缩聚梁建模方法建立了薄壁贮运筒动力学等效模型，以刚体动力学模型求得的贮运筒受力为动载荷输入，利用瞬态动力学的方法，实现了水下发射过程贮运筒变形的解耦计算。通过调整贮运筒弹性支撑的刚度及位置，论证分析了航行体水下发射过程薄壁贮运筒变形与弹性支撑布置位置、刚度、阻尼的关系，研究了水下发射过程薄壁贮运筒变形控制方法。
The rigid body dynamics calculation model of the underwater launching of the vehicle is established, and the force of the storage tank during the underwater launching process is calculated and extracted. A dynamic equivalent model of the thin-walled storage tank was established by the method of condensed beam modeling. The force of the storage tank obtained by the rigid body dynamics model was used as the dynamic load input. Using the method of transient dynamics, the decoupling calculation of the deformation of the storage tank during underwater launch is realized. By adjusting the stiffness and position of the elastic support of the storage tank, the relationship between the deformation of the thin-walled storage tank and the arrangement, stiffness and damping of the elastic support is demonstrated and analyzed, and the deformation control method of the thin-walled storage tank during underwater launch is studied.
