SUMMARY

The discussion focuses on the mechanisms behind vibration in sanders, specifically how electric motors and piezoelectric transducers generate periodic motion. Vibration is defined as a mechanical motion where mass is translated back and forth, which can be achieved using linear or rotational electric motors. Additionally, piezoelectric materials can create vibrations by periodically activating an electric field, serving as the foundation for ultrasonic devices.

PREREQUISITES
  • Understanding of mechanical motion principles
  • Familiarity with electric motor types (linear and rotational)
  • Knowledge of piezoelectric materials and their applications
  • Basic concepts of ultrasonic technology
NEXT STEPS
  • Research the operation of linear and rotational electric motors in detail
  • Explore the principles of piezoelectricity and its applications
  • Learn about ultrasonic devices and their uses in various industries
  • Investigate the design and functionality of vibration sanders
USEFUL FOR

Engineers, product designers, and hobbyists interested in the mechanics of vibration tools, particularly those involved in the design and application of sanders and ultrasonic devices.

I interest how can vibration be maked.That is,for example sander.how does the mechanism of the vibration sander functions?is there any idea?:rolleyes:
 
Physics news on Phys.org
Vibration is a period mechanical motion, i.e. some mass is translated back and forth over a given displacement field. Such motion can be obtain with a linear or rotational (orbital) electric motors, which produces a periodic motion.

Piezoelectrics can also produce vibration by turning the electric field on and off periodically. See -

http://en.wikipedia.org/wiki/Piezoelectric_transducer

Piezoelectric transducers are the basis of ultrasonic devices.
