Mathematical Modeling of Vibration Dampers of Vibration-Insulated Structures

Vibration dampers are installed on the machine foundations in order to reduce vibration level. Such technological solutions most expedient case of a harmonic load with low instability frequency. Unfortunately, do not provide such large reduction dynamic effect base, as isolation, but some cases their efficiency turns out be quite sufficient relatively simple implementation and manufacturing cost. The use gives great when an increased occurs during operation equipment metallurgical production, for example, processing materials by pressure, reconstructing enterprises replacing heavy equipment. During forging manipulators various purposes, these devices can considered rigid body. model soil which this foundation is homogeneous elastic isotropic half-space. When calculating mathematical models, one corresponding contact problems. A comparative analysis effectiveness damping vibrations using different including elastic, half-space system semi-infinite rods, modulus elasticity increases depth according quadratic law, shows fairly close agreement.
