Abstract [en]

This thesis objective is to present a suitable high acceleration test method for SAAB Dynamics. SAAB is in need for an easy to use and cheaper way to test components such as the fuze and electrical components embedded in the fuze system. SAAB Dynamics develops ground combat weapon systems for the global market as well as civilian products. Products produced by SAAB are being used in armed combat, making this thesis project somewhat controversial. However, the concept produced by this work can be used in civilian applications such as aeronautics, space and material science.

This thesis focused on using systematical methods and research to gain as much knowledge about the needs and demands of the customer, in this thesis SAAB. The project presents its own concepts as a valid option instead of buying one from a supplier. The concept is based on the needs of SAAB and is generated through creative brainstorming sessions and a morphological matrix. The concept was benchmarked together with similar test methods and test benches on the market.

In order to be able to present a suitable concept the project conducted a large feasibility study of the fuze system and the products in need of testing as well as how other industries test similar acceleration and impacts.

The concept consists of a high-grade industrial compressor in order to generate high air pressure inside a pressure chamber. The built up pressure breaks a sensitive disc and releases the air into the launch chamber. In the launch chamber, the projectile accelerates through a rifled pipe and then travels freely in a wider pipe. The projectile then deaccelerates when impact occurs with an energy absorption material such as aluminum honeycomb or foam.
