Abstract
A flexible-support technique with blank travel for depressing load over cover system was brought forward. The fluid field near canister outlet for underwater-aunched emulating missile and its effect on cover system were modeled and simulated using a 3D symmetric model based on dynamic meshing technique and VOF model with phase transformation. The characteristics of bubble pulsation near canister outlet, time-variable load over the cover and its supporting component and dynamics characteristics of cover were achieved through simulation of 9 cases. The results show that flexible-support technique with blank travel for depressing load over cover was feasible. It provided a new kind of reference standard for load-depressing cover system design.
