One of the most proven ways to reduce satellite launch vehicles fuel consumption is to use multistage separation systems. These separation systems based on mechanism of operation divided into two category, explosive and non-explosive. Nowadays, non-explosive separation systems have been considered due to their features such as ease of maintenance, reduction of explosion hazards and reduction of shock to payload. One type of non-explosive separation systems is separation systems based on CBOD (Clamp Band Opening Device) releaser. In this study, changing the dimensions (geometry and thickness) of the flywheel which is one of the effective parameters in the CBOD release performance, have been investigated. Adams software (ADAMS) was used for simulation and the Results have been validated using experimental test on sample made by 3D printer. The parameters of separation time, linear acceleration of Counter-clockwise screw along separation axis and angular acceleration of flywheel around separation axis has been selected as output parameters. It was found that the increase in diameter and thickness of the flywheel is directly related to the separation time and inversely related to the angular acceleration of the flywheel around the separation axis and the linear acceleration of the Counter-clockwise screw along separation axis. Also, with increasing moment of inertia and mass of the flywheel, the amplitude of acceleration fluctuations has decreased.
