Improvement of Dynamic Characteristics of Electromechanical Commutating Devices 1999-01-1710

Modern production is intensified by the extensive application of computing art to structure design. This paper deals with the results of numerical simulation of electromechanical commutating devices. Speed of operation, vibrostability, reliability and durability are basic characteristics, which can be satisfied by studying mathematical models of mechanical and magnetic systems. During the impact interaction of elastic links several modes of vibrations are excited. By developing certain conditions, the amplitudes of the higher modes can be increased by changing the intensity of energy dissipation and responsiveness of the mechanical system. Such parameters as the position and configuration of the contact elements, ratio of their natural frequencies and others should guarantee the smallest amplitudes of rebounds with a possibility to minimize transient processes occurring in the building ofthe operation. This approach inreases the speed and stability of the commutating device under the external vibrations or shock excitation of a moving vehicle.
