J,the increased extension. In such cases, to provide the required stiffness of the system and to avoid the high level of vibration activity, the executive body is driven by multiple duplicated cyclic mechanisms. This vibatory system forms the closed contours and acquires the so-called ring structure,

These schematic and design solutions are fairly common in the textile, printing, packaging machines, and other industries, for moving not only massive tables or carriages, but also for relatively compliant working bodies forming the beam and

Nonlinear Dissipative Forces,This chapter presents methods of equivalent linearization of nonlinear dissipative forces with polyharmonical vibrations on the basis of the limited information obtained experimentally with monoharmonical excitation. The material is of general engineering interest and applicability and is not limited cyclic machines.

F,Here is presented the information about classification of mechanical vibrations, initial data and the principles of dynamic model creation, typical dynamic models of cyclic systems, and their classification. The elements of the dynamic models and their reduction are also included.

G,f vibration excitation are analyzed. The ways to reduce vibration activity and enhance the accuracy of reproduction of the given laws of program motion are presented. An original problem of the synthesis of cyclic mechanisms with quasi-constant amplitude–frequency characteristics is considered.
