A theoretical condition where no energy is lost, and the system continues to oscillate indefinitely. 3. Key Components & Modeling Mass ( ): Inertia component resisting acceleration. Spring ( ): Elastic component providing restoring force, modeled by (Hooke's Law). Damper ( ): Energy dissipation element (e.g., shock absorber).
The number of independent coordinates needed to define the system's motion. 4. Analysis & Applications
Methods to reduce undesirable vibrations, including vibration isolation (using isolators) and structural damping. mechanical vibration
Caused by external periodic, transient, or random forces (e.g., an unbalanced washing machine).
Involves measuring amplitude and frequency to identify the root cause of issues, such as unbalance, misalignment, or looseness. A theoretical condition where no energy is lost,
Swaying motion of a structure around an equilibrium position. Core Parameters:
Occurs after an initial disturbance; the system oscillates at its natural frequency without external force. Spring ( ): Elastic component providing restoring force,
): The frequency at which a system oscillates when disturbed and allowed to vibrate freely, calculated by
