adminVIBRATING SYSTEMS
Vibrating systems are dynamic systems that exhibit oscillatory motion or behavior and their design, analysis and control are critical for ensuring performance, safety and efficiency of both static and dynamic systems.
The design of vibrating systems involves the following measures; system requirement, material selection, component design and modal analysis.
The system requirements defines physical characteristics such frequency range, amplitude and mode shape.
The material selection involves selecting materials with suitable properties such as stiffness, mass and damping.
The component design involves the design of physical components such as spring, dampers and masses to meet system requirements.
The modal analysis is performed to identity natural frequencies and mode shapes.
The advantages of vibrating systems are as follows; vibrating systems can be used to harvest energy from environmental sources such as wind, tidal and ocean turbines. Vibrating systems can be used to process signals and extract information such as the microphone, speakers etc. vibrating system can be used for sensing and actuation in various applications. Vibrating systems can be used to mix amd blend materials more efficiently. Vibrating systems can be used to convey materials from one point to another. Vibrating systems can enhance heat transfer in certain application. In some cases controlled vibration can increase fatigue life by reducing stress concentrations. Vibration analysis can be used as a diagnostic tool to detect faults and anomalies in machines. Vibration can be used to process materials such as ultrasonic cleaning or material shaping.
