Abstract
The methodology described enables high accuracy in the measurement of static and dynamic stiffness and dent resistance.
Among the parameters being evaluated are: stiffness and dent resistance of the automotive outer body assembled panels – under both static and dynamic loading and the effect of the stiffening features in the panel shape, upon its deformation characteristics under dynamic excitation and dynamic wave propagation following slow projectile impact.
This methodology will help part and process designers to correctly position and manufacture outer and inner body features like door handle embossment shape and location, feature lines, lamp and mirror embossments, hemming lines and side bar locations.
Measurements are carried out using the stereo photogrammetry system ARAMIS – a fast and cost effective tool with a high accuracy of displacement measurement in both static and dynamic conditions. Measurements were performed in real time related to the phase of elastic wave generated by projectile impact. Parameters of the elastic wave were defined using laser displacement sensors and accelerometers with a linear accuracy of 0.5 μm.
