Produktutveckling av vapentillbehör för Kulspruta 58

This thesis work has been conducted on the behalf of the Swedish Defence Material Administration, within the department of Soldier carried weapon systems. The study covers weapon accessories for the general purpose machine-gun, FN Mag 58. The task has been to analyse the existing accessories and compile possible improvements. Furthermore a new concept for carrying ammunition was also to be developed. The specification for requirements have mostly been created from analysis off previously conducted trials and reports. But also after discussions with employees from FMV and the Swedish armed forces. The process of rendering concepts has been in line with Ulrich and Eppingers product development theories. Where the larger concept has been broken down into smaller projects. Evaluation of concepts has been conducted with Pugh matrixes. To further validate critical solutions in the concept, calculations and trials have been performed. The result consists of documented suggestions for improvements on the existing accessories and a technical description for a new carrying system for ammunition. The technical description is supplemented by a Solidworks CAD model to further show function and form with greater detail. The emphasis in the solution has been to create a flexible and modular system
