Abstract [en]

The aim of this thesis has been to try to improve vibration testing of electrical and electromechanical components that are used within Scania’s segment of the vehicle industry. To do this, guidelines regarding the design of vibration test fixtures has been developed. Since every fixture is mounted on a bottom plate during vibration testing these bottom plates have also been under study and a proposal for a standardized bottom plate is presented. In order to be able to easily test components with basic designs a modular fixture has also been designed, manufactured and evaluated within the scope of this thesis.

Implementation of the proposed guidelines for fixture design is most importantly argued to enable power transfer between the component and fixture during testing that as far as possible resembles the power transfer that takes place when the component is mounted on/in an actual vehicle. Using the standardized bottom plate and producing new fixtures to fit the same hole pattern is argued to decrease the work load for each vibration test considerably. Finally good results are shown regarding the performance of the modular fixture.
