Development and evaluation of concepts for a high acceleration test rig : Development of a test rig, which aims to expose components to large and controllable accelerations

Jansson, Axel January 2023 (has links)
This thesis work is dedicated towards finding a feasible test rig design, which can expose small components, produced by SAAB, to a variety of accelerations under different conditions. A literature study is conducted with the objective of gathering information regarding high acceleration testing, where relevant components, designs and calculation methods are presented. A series of concepts are presented and evaluated against a requirement specification, the first concept iteration concerns the method of acceleration whereas the second and the third concept iterations concerns the design of the test rig on different levels of detail. The third concept evaluation is strengthened by several calculations, which indicates the feasibility of the concept in some manner. One concept achieved the highest score in the third concept evaluation and as such is presented as the best suited concept for further development. / Denna avhandling är dedikerad till framtagningen av en möjlig design för en provningsrigg, som kan utsätta små komponenter, som produceras av SAAB, för flera olika accelerationer under olika förhållanden. En litteraturstudie genomförs med syftet att samla information om provning under höga accelerationer, där relevanta komponenter, designer och beräkningsmetoder presenteras. En serie koncept presenteras och utvärderas med hjälp av en kravspecifikation. Den första konceptiterationen berör metoden för acceleration, medan den andra och den tredje konceptiterationen berör designen av provningsriggen. Den tredje koncept utvärderingen stärks av flera beräkningar, som indikerar konceptets lämplighet ur något perspektiv. Ett koncept uppnådde högst poäng i den tredje koncept utvärderingen och presenteras därav som det bäst lämpade konceptet för vidare utveckling.
