A separation device based on cubesat was designed. First of all, according to the requirements of the cubesat separation speed, the mechanical structure of separation mechanism and separation spring parameters were designed. And then, on the basis of above results, the dynamics model of separation mechanism was established through numerical calculation of the dynamics model to confirm the elasticity coefficient of the torsional spring which met the requirements of non-interference separation. Based on the electrical requirements of separation mechanism, short-circuit measures electromagnet protection circuit and telemetry circuit was designed. Simulation and test of cubesat and launch vehicle and the detection of separation and telemetry function of separation device showed that the initial velocity of cubesat and the telemetry function of separation mechanism completely satisfies designed technical indexes.
