Exciting force of vibration
Since
vibration has a solid meaning, a dynamic force must be applied to create
vibration, which is a repetitive motion. Therefore, when analyzing this dynamic
force, it can be divided into the following three exciting forces.
-Centrifugal force that induces mass
imbalance due to rotational motion
------------
In
addition, electromagnetic force caused by electricity can also be said to be an
exciting force that causes vibration. Examples include electrical defects in
motors or shakers caused by electromagnetic force.
The
main problem caused by vibration is fatigue failure due to repetitive fatigue
of solids. This gradually lowers the durability limit of objects and causes
major destruction of objects and machines at critical moments.
