Measurement of strain of the 3D printed space frame of automotive headlamp by digital image correlation method

Original language description

This paper discusses and introduces a non-contact method for measuring the deformation of a 3D printed spatial structure by DIC (digital image correlation). A prototype of automotive headlight frame was chosen as the 3D printed structure. The chosen material for 3D printing was EOS MaragingSteel MS1/400W metallic powder. Another part of the work was to design the loading of the headlamp support structure under limit states in operation. The limit state in this case means crossing the transverse threshold at a given speed. These data were measured during experimental runs with the measuring device. Then the work focuses on the design of the measuring device and the measurement of the deformation under static loading. In this case, the design of the measuring stand with the support of the non-contact deformation measurement method DIC was considered. For the purpose of noncontact measurement, the stand and the 3D printed structure were provided with the necessary injection moulding that was required to capture the deformation occurring under load. The results from the non-contact measurement were compared with the control results from the FEM analysis. Simplified 3D models were used for the FEM analysis. The load on the 3D printed structure was measured using a force gauge. The last part of the paper deals with the evaluation and validity of the measured data with the assumptions from the FEM analysis. The aim of the thesis is to evaluate the measured results with a view to designing an optimization of the 3D printed structure so that it still meets the strength requirements that are placed on the headlight of a car.
