We want an analytical model where the natural frequency matches the measured values!
"Model correlation" refers to the process of reviewing various possible errors and correctly reflecting them in the analytical model. If there are measured values and an error-free analytical model, it becomes possible to apply this to further simulations, thereby demonstrating the true value of the simulation. Therefore, by combining Quint products, we propose an experimental vibration characteristic and an error-free analytical model = an optimal model correlation. In this case study, we derived an analytical model that reproduces the vibration characteristics of a plate with a complex structure, including a honeycomb core material (hereinafter referred to as "honeycomb panel"), using Quint products "VOXELCON," "AMDESS," and "OPTISHAPE-TS."
