The synthesis of autonomous oscillators with exact desired periodic steady-state solution is described in this contribution. The vector field of the oscillator differential equation is built up with a conservative and a dissipative part. Both parts a

In nature many interactions of different oscillatory systems can be described by the phenomenon of synchronization. This phenomenon can be widely used for engineering applications. In this contribution, the synchronization between a self-sustained os

The synchronization of a controlled unbalanced rotor with a viscoelastically mounted supporting body and force-excitation is studied. The existence and stability conditions for the synchronous regime of motion are derived for a general control law by

For overconstrained single-loop mechanisms with helical joints (nH mechanisms) necessary conditions for the finite mobility are derived using a local approximation of the loop closure conditions by means of a Taylor -series expansion of the 1st-order

A single-loop mechanism with n≤6 helical joints which has a finite mobility with a degree of freedom f≥1 is overconstrained. Here the case f=1 is considered. For the finite mobility of an overconstrained mechanism it is sufficient, that the first

An approach for the synthesis of overconstrained single-loop mechanisms with helical joints using screw theory is presented. By expressing higher-order derivatives of the screw axes with respect to the joint coordinates a local approximation of the c
