WebJan 1, 2014 · The undamped free vibrations described in the previous section never occur in nature. More realistic free vibrations are modeled by adding a damper into the spring-mass system shown in Fig. 3.2, which results in an SDOF spring-mass-damper system as shown in Fig. 3.7. It is assumed that the damper is of viscous type with a damping … WebThe conservation of energy method is based on the time derivative of the total energy of an undamped system. (2.1) Apply this method to the SDOF system in Figure 1.1 to derive the equation of motion. (2.2) (2.3) …
Web5.5.4 Forced vibration of lightly damped linear systems with many degrees of freedom. It is quite simple to find a formula for the motion of an undamped system subjected to time varying forces. The predictions are a bit unsatisfactory, however, because their vibration of an undamped system always depends on the initial conditions.
