BISOPE series 64 Cause of vibration force excitation force and degree of analysis

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
-Inerated by the collision of fluid and solid
-Electrical vibration noise generated by electric and electromagnetic forces such as high-voltage lines, rectification, and piezoelectricity.
Among these, the excitation force that can be problematic in machine vibration analysis is mainly rotational movement, and the vibration caused by impact force and self-excited vibration is a decisive factor in the difficulty of vibration analysis.
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.
