Methods to reduce undesirable vibrations, including vibration isolation (using isolators) and structural damping.
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).
Occurs after an initial disturbance; the system oscillates at its natural frequency without external force. mechanical vibration
MATLAB is commonly used for solving complex, high-degree-of-freedom, or non-linear vibration equations. Mechanical Vibration
Energy is gradually dissipated (by friction or resistance), causing vibration amplitude to decrease over time. Key Components & Modeling Mass ( ): Inertia
A dangerous condition occurring when the external forcing frequency matches the system's natural frequency, leading to high-amplitude, damaging vibrations. 2. Types of Vibration
The maximum displacement from equilibrium, indicating vibration intensity. Frequency: The speed of vibration ( ), measured in Hz, reflecting cycles per second. Occurs after an initial disturbance; the system oscillates
Involves measuring amplitude and frequency to identify the root cause of issues, such as unbalance, misalignment, or looseness.
