Abstract: 
We model dynamic process in the system of adapters of a launch vehicle and spacecraft, caused by the impulse effect of activation of electroexplosive devices during separation stage. We used three-dimensional “finite element method” models and a special method to account for a surface of adapter separation, needed to model the unilateral contact. Time modeling is done using finite difference Wilson θ-method. We also show the obtained results of adapters’ kinematic characteristics and the impact spectra.
Keywords: accelerograms, adapter, contact, dynamics, finite element, range strike, separation, space design
