Dynamic Models of Cyclic Mechanical Systems,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.

Dynamic Models with Constant Parameters,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.

Clearances,sented for analyzing the excitation of vibrations due to impacts in kinematic pairs and during shockless reversals in clearance joints (pseudo-impact). Taking into account the clearances, the dynamic synthesis of cyclic mechanisms based on some criteria of efficiency of dynamic unloading is worked out.

Vibration Analysis of Cyclic Machines Using Modified Transition Matrices,on to elastic and inertial elements, the kinematic analog of cyclic mechanisms is entered. The analysis of generalized vibratory systems of mechanical drives with complex structure and joints accounting dynamic characteristics of the motor and the machine drive are under consideration.
