FIELD: the invention refers to forecasting characteristics of own frequencies in a subsystem of pipes which includes silphon components covered with a casing. ^ SUBSTANCE: the coefficient of rigidity in each silphon components covered with a casing is defined by way of using the method of regression which is based on data of tests on dynamic rigidity. The defined coefficient of rigidity in the model is used for forecasting of own amplitude-frequency characteristic. The position of rod end links of the supports of the pipeline is defined along the forecasted characteristic. ^ EFFECT: increases accuracy and profitableness. ^ 5 cl, 3 dwg |
