In ANSYS FEA, Modal Analysis finds a structure's inherent vibration characteristics (natural frequencies and mode shapes) to prevent resonance, while Harmonic Analysis applies cyclic loads over a frequency range (sine sweep) to predict the structure's response (displacement, stress) at specific frequencies, often using modal results for efficiency (mode superposition). Vibration analysis encompasses both, studying how structures react to dynamic forces, with modal analysis informing the frequency range for harmonic analysis to avoid dangerous resonance.
