No full textOn the computation of degrees-of-freedom: a didactic perspective
No full textSome didactic issues associated with the computation of degrees-of-freedom (d.o.f) are herein discussed. In particular, the paper reports different definitions and methodologies of computation of this important parameter It is also proposed an analytical approach to the d.o.f computation of planar figures subjected to unilateral constraints. Mechanisms with variable kinematic structure are included in the present analysis. Some ambiguities in the d.o.f definition are pointed out
Sull'enumerazione di meccanismi a vite
No full textEnumeration of mechanisms is classical field in kinematics. In this investigation it is addressed the
problem of enumeration of screw mechanisms. It has been proposed a new method of enumeration of these mechanism
class and somewhat new kinematic chains have been discovered. The method based on some noteworthy
relations deduced by R. Kraus, makes use of the polynomial characteristic isomorphism test adapted for labeled
graphs
