Abstract [sv]

Detta examensarbete har utförts vid Saab Dynamics AB(SBD) i Karlskoga med syftet att studera gamla konstruktioner av set-back-generatorer. En set-back-generator (SBG) ska ge momentan energi vid utskjutning av en projektil genom att en magnet rör sig genom en spole. SBG har funnits länge men har bedömts ge för lite energi för att kunna driva elektronik. Men nya typer av magneter har potential att öka energiutbytet väsentligt.

SBD har ett antal äldre SBG:er och arbetet har varit att utifrån dessa undersöka om det går att utvinna mer energi genom ett utbyte av magnet. Andra parametrar som är viktiga för en SBG:s funktion har också studerats och testats i olika konfigurationer i hopp om ytterligare förbättringar. Förväntade resultat har sedan analyserats och jämförts med mätresultat. Med detta som grund har rekommendationer vid en ny konstruktion av SBG levererats.

Abstract [en]

This bachelor thesis has been performed at Saab Dynamics AB (SBD) in Karlskoga, with the purpose to examine old designs of set-back-generators. A set-back-generator (SBG) shall provide instantaneous energy during firing of a projectile by a magnet moving through a coil. Previous designs of SBG:s is not providing enough energy to power electronics. New types of magnets have the potential to increase the energy yield significantly.

SBD has a number of older SBG's and the work is based on these to examine the possibility to extract more energy by exchanging magnet. Other important parameters for an SBG's function has also been studied and tested in different configurations in the hope of further improvements. Expected results has then been analyzed and compared with the measurement results. On this basis suggestions and recommendations on a new SBG design has been delivered.
