WebbQuestion for GATE Past Year Questions: Forced Vibration Try yourself: A vehicle suspension system consists of a spring and a damper. The stiffness of the spring is 3.6 kN/m and the damping constant of the damper is 400 Ns/m. If the mass is 50 kg, then the damping factor (d) and damped natural frequency (fn), respectively, are [2009] A. WebbVibration signals were measured under a variety of different situations, including forced and free vibration, using sampling theory and data gathering techniques. In this experiment, it was discovered that the natural frequency is mass dependent, and that different system parameters will alter depending on its value. ravenswood connect

WebbForced Vibrations : When a repeated force continuously acts on a system, the vibrations are said to be forced vibration. The frequency of the vibrations depends upon the applied force and is independent of there own natural frequency of vibrators.
