China Wholesale Velocity Quotes – LMEC-8 Apparatus of Forced Vibration and Resonance – Labor Detail:

Forced vibration and resonance phenomenon are often used in engineering and scientific research, such as in construction, machinery and other engineering, it is often necessary to avoid resonance phenomenon to ensure the quality of engineering. In some petrochemical enterprises, resonance phenomenon line is used to detect liquid density and liquid height, so forced vibration and resonance are important physical laws, which are more and more popular in physics and engineering technology Attention. The instrument uses tuning fork vibration system as the research object, electromagnetic force of electromagnetic exciting coil as exciting force, and electromagnetic coil as amplitude sensor to measure the relationship between vibration amplitude and driving force frequency, and study forced vibration and resonance phenomenon and its law.

Experiments

1. Study the relationship between amplitude and force frequency of a tuning fork vibration system driven by a periodically external force. Measure and plot their relationship curve, and acquire the resonance frequency and the sharpness of the vibration system (this value is equal to the Q value).

2. Measure the relationship between the vibration and the mass of symmetrical arms of the tuning fork. Acquire the relationship formula between the vibration frequency f (i.e. resonance frequency) and the block mass m attached to the tuning fork arms at a certain position.

3. Determine the mass of a pair of mass blocks attached to the tuning fork arms by measuring the resonance frequency.

4. Measure the resonance frequency and sharpness of the tuning fork when changing the vibration structure and increasing the damping force of the tuning fork and do comparisons.

The instruction manual contains experimental configurations, principles, step-by-step instructions, and examples of experiment results. Please click Experiment Theory and Contents to find more information about this apparatus.
