EXPERIMENTAL RESEARCH METHODS OF SHOCK AND VIBRATION FIRMNESS OF CONSTRUCTION ELEMENTS OF COSMOS DEVISES

摘要

In this paper the questions of methodical provision and means for experimental investigations of cosmos devices (CD) constructions by the actions of transient force pricesses are considered. Necessary more accurate definition of modelling method of the interaction is accounted in the algorithm of the forming of test signal which is corresponds to natural force action on CD. For this purpose test complex have created on the basis of electrohydraulic stand PLz 250 x/s and control system with PC AT. The way of conduction of experiments orientates on iteration process of the forming of loading signal on all level of excitement. Iteration process of the control is ended when required time function of small level arrives at check point. After that have formed signal of the load increases to getting of required time functions and creates in the constructions as single it. The reproduction of setting end time function presenting transient process n setting of construction is the aim of the test.
