Degree of Freedom:
- The DOF of a mechanism refers to the number of independent parameters required to completely specify the configuration of the mechanism in space.
- According to Kutzback's equation of DOF
DOF = 3(n - 1) - 2j - h
where, n = Number of links, j = Number of joints, h = Number of higher pairs in mechanism.
The physical interpretation of DOF:
- DOF < 0, Overstructure/Superstructure
- DOF = 0, structure /Frame/Truss
- DOF > 0, Mechanism
- DOF of a mechanism predicts the possible number of output with respect to a given input.
- DOF also predicts the number of inputs required in order to obtain a constrained mechanism or number of links that should be controlled as input in order to have a single output.
