Luo, “ Periodic motions in a single-degree-of-freedom system under both an aerodynamic force and a harmonic excitation,” in Proceedings of the IDETC/CIE, Anaheim, CA, 18–21 August (ASME, 2024), ASME Paper No.: DETC2024-97716, V008T10A026; 6 pages. WebThe motion that the system performs under this external agency is known as Forced Simple Harmonic Motion. The external force is itself periodic with a frequency ωd which is known as the drive frequency. A very important point to note is that the system oscillates with the driven frequency and not its natural frequency in Forced Simple Harmonic ...
WebExample 1: A structure is idealized as a damped spring—mass system with stiffness 10 kN/m; mass 2Mg; and dashpot coefficient 2 kNs/m. It is subjected to a harmonic force of amplitude 500N at frequency 0.5Hz. Calculate the steady state amplitude of vibration. Start by calculating the properties of the system: Web3. A spring-mass-damper system is subjected to a harmonic force. The amplitude is found to be 20 mm at resonance and 10 mm at a frequency 0.75 times the resonant frequency. Find the damping ratio of the system.
