Calculation of amplitude-frequency characteristics bellows compensators using experimental vibration decrement constraints
Results of experimental determination of oscillation decrements on 78 samples of corrugated shells (bellows) and on 22 samples of serial bellows compensators are given. Dependencies of oscillation decrements on amplitude in resonance region are constructed, approximating functional dependence is selected, regression coefficients of which were determined during processing of corresponding experimental data by least squares method using dependencies of oscillation decrements are calculated and amplitude-frequency characteristics (ACF) of bellows compensators are built.
