Forecasting longitudinal vibrations of spacecraft structure and equipment during the pulsation of engine thrust

Abstract

The article analyzes the effect during a pulsation of engine thrust, presents models and methods for estimating the spectral density of vibration overload and section displacement, which make it possible to predict the vibration load of the spacecraft compartment and spacecraft equipment, taking into account the shock absorber, for various constructive solutions in a wide range of initial data. The efficiency of the presented approaches is illustrated with specific examples in various sections of the spacecraft body. The obtained results can be useful to engineering and technical specialists of organizations, as well as to students of the corresponding educational field.
