BISOPE series 26- freedom, natural, degree of freedom, free vibration

--------------------------------------------------------------------------------------------------------------------------------------

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......
