Transient vibrations usually occur when a system is excited by a sudden, non-periodic excitation. The magnitude of such oscillations varies based on the type of excitation, and they occur at the system's natural frequencies. Examples include the impact of a baseball bat or cricket bat on a ball, non-destructive testing procedures, vibration monitoring techniques, and even the response of a building during an earthquake. The mode-superposition method is a good way to forecast how a structure will respond to various loads. Hence providing answers to queries related to the response's peak amplitude, timing, and time to decay. In this video lesson, we start with a short lecture and then get into a workshop example in Ansys Mechanical. // INTERESTED IN MORE?
