Features of statical and dynamical weighting in mechanical oscillation systems. Tasks of vibration protection

Abstract

Methodological base for solution of tasks of identification position statical balance and appropriate responses in connections of system elements between themselves and base surface is offered. Algorithmical basis of responses estimation at different forms of acting external forces is developed. Features of formation of statical balance at several masses were considered. Is shown that statical balance is depend on external forces structure and on elastic compact structure. Such a  elastic elements complex is formed in supposition of «nulling» of intermediate masses at certain points of forces application. Definitions about displacement of system points at absence of straight application of external force. Is shown that estimation statical responses task in system with elastic elements can be solved on base dynamical approaches when elastic mechanical system is compared structural scheme of equivalent in dynamical relation of structural scheme of automation control system. Is supposed that in Laplas transformations complex variable which reflects external force action, is assumed equal zero. This situation follows from preliminary getting of kinetostatics equation on base of Dalamber principle with consequent conversion to statics equations at p?0. Proof of possibility of using of transfer functions apparatus for decision of statics tasks is feature of offering approach. Recommendations and appropriate analytical correlations are got which is allows to introduce in consideration features of formation of statical responses in systems with several degrees of freedom at action of several statical forces.
