--------------------------------------------------------------------------------------------------------------------------------------
The word freedom is also used as a vibration engineering
term, and is used together with a coordinate angle to express the motion and
vibration phenomena of an object in a formula. In other words, in vibration,
there must be coordinates to mark the vibrating object as the amplitude and
frequency of displacement, velocity, and acceleration. At this time, the term 'degree
of freedom' of vibration is used. I think freedom is equal to #Eigen
value. Because the state that produces its own characteristics is
freedom itself.
DOF & Free(natural) vibration
The number of coordinates expressing the behavior of a system
is called ‘degrees of freedom’.
To explain this, to explain a single spot, the movement of a spot has 3 degrees of freedom (x, y, z axes), and a rigid body in free space (an object that does not connect to each other between each degree of freedom) has 6 There are degrees of freedom (each axis + angular rotation direction). Also, an elastic continuum (a real object in nature) has......
