摘要
Abstract
The mechanical property of the adapter between missile and tube directly affects the dynamic characteristics of the underwater missile vertical launching process,and it is the key factor for the interior ballistic control.Currently,most studies simplified the representation of adapter deformation characteristics and could not reflect its nonlinear mechanical property.Therefore,there are certain errors in the theoretical model.By considering the hyper elasticity and hysteresis of stress-strain curves of the actual adapter material,a new method for modeling the adapter is proposed.The result shows that damping capacity of the actual adapter can be represented accurately by this new model and the problem of the adapter's vibration frequency increase when reducing amplitude by increasing the adapter stiffness can be solved by optimizing the structure of adapters.关键词
