Free vibration occurs when a mechanical system is disturbed from its equilibrium position and allowed to oscillate freely without any external forces acting on it. This type of vibration is commonly observed in various engineering applications such as bridges, buildings, and machinery.
Characteristics of Free Vibration
Free vibration is characterized by the natural frequency of the system, which is the frequency at which the system vibrates when no external forces are applied. The amplitude of the vibration gradually decreases over time due to energy dissipation. The motion of the system follows a sinusoidal pattern, where the displacement, velocity, and acceleration are all periodic functions of time.
Natural Frequency
The natural frequency of a system is determined by its stiffness and mass properties. A system with a higher stiffness will have a higher natural frequency, while a system with a higher mass will have a lower natural frequency. The natural frequency is a fundamental property of a system and plays a crucial role in determining its dynamic behavior.
Mode Shapes
During free vibration, the system exhibits characteristic mode shapes, which represent the spatial distribution of the vibration within the system. Each mode shape corresponds to a specific natural frequency of the system. The mode shapes are unique to each system and provide valuable insights into its structural behavior.
Overall, free vibration is an essential concept in the field of structural dynamics and mechanical engineering. Understanding the natural frequency and mode shapes of a system helps engineers analyze its dynamic response and design efficient structures that can withstand vibration effects.
