These criteria are met for both mounting variants. The rigid body modes occur in both variants at around 30 Hz, but in the upright mounting variant, some resonances are less distinct and between 600 Hz and 1000 Hz additional peaks are present. The upright mounting method’s advantage of a quicker setup is offset by the disadvantage of overestimating the modal damping values and additional resonances. As well as the mounting method, the stinger used to join the structure and shaker also has a major influence on the experiment result (Fig. 4). The blue curve relates to a stinger variant with two clamp sets and the green curve relates to a variant with a simple stud screw clamp fixture. The results are similar in principle, though the simpler variants exhibit additional resonances in the low frequency range and much less distinct resonances in the high frequency range. Consequently, the short, thin, rigid-fixed stinger is better suited to the structure under investigation and to measurements in the frequency range above 1200 Hz.
Modal analysis is conducted by the Block-Lanczos method available in MD Nastran. To correlate the two models (Fig. 5), the experimental data is imported into MATLAB using the UFF format while the numerical data is imported by use of the MATLAB/Nastran interface IMAT FEA. The two datasets are then automatically positioned and correlated. For the first 16 eigenfrequencies, this results in a mean MAC correlation (Fig. 6) of 91% and a mean frequency variation of 1.28%. The MAC correlation is better in the low modes, while the frequency correlation is better in the higher modes.
