The paper is concerned with torsional buckling of a system composed of two parallel shafts coupled together by two mechanisms. The motion of the system is described by a set of non-linear differential equations with coefficients which are periodic functions of displacements. Fixed points, closed orb

✦ Synopsis
The paper is concerned with torsional vibration of a system composed of two parallel shafts coupled together by a number of mechanisms. The analysis has been done by using both non-linear and approximate linear equations. It is shown that there are three predominant sources of vibrations: (i) the tendency to different speed fluctuations of each mechanism; (ii) different mode configurations of the shafts; (iii) the fact that the inertia and the stiffnessof the system are not varying proportionally to one another. The instability regions, the vibration amplitude and the range of fluctuation of the driving torque for a double crank-and-rocker mechanism are illustrated graphically.

A transverse surface crack is known to add to the shaft a local flexibility due to the stress-strain singularity in the vicinity of the crack tip. This flexibility can be represented by way of a 6 • 6 matrix describing the local flexibility in a short shaft element which includes the crack. This mat
