Finite element analysis is a computerized method widely used in industry to model and solve engineering problems relating to complex systems. Perhaps the most common use of finite element analysis is in the field of solid mechanics where it is used to analyze structural problems. To achieve the correct results the component and all mating interfaces must be modeled properly. Previously this was done by performing the analysis, manufacturing a prototype based on this design, and then physically determine the natural frequencies of the prototype attached to the interface structure. Once the actual natural frequencies are determined, the boundary conditions and other modifications of the finite element model are adjusted using a trial and error method until an acceptable correlation with the measured frequencies is achieved.
