Opto-mechanical design and analysis of military vehicle headlight system

In this thesis, it is aimed to opto-mechanical design of a military vehicle headlight system that provides illumination with high efficiency solid-state leds and perform thermal and structural analysis with finite element method. The body of the opto-mechanical system is designed to keep the led junction temperature at optimum level with the help of the thermal analysis according to the lighting pattern specified in the regulations. Equivalent stresses are obtained by structural analysis to control the connection interface between the system assembly and the vehicle. Modal and random vibration analysis were performed to observe the effects of the high vibration profile that the system would be exposed to. As a result of the analysis, a prototype has been manufactured for the optimised model and tests were performed to compare with the analysis results.
