Computer Simulation of the Natural Vibrations of a Rigidly Fixed Plate Considering Temperature Shock

This paper presents the results of a computational experiment on the natural vibrations of a homogeneous rigidly fixed plate after a temperature shock. Unlike in many well-known studies, in this work, the plate is not stationary at the moment of thermal shock. This formulation has wide practical applications. For example, as a result of the unfolding of solar panels, free vibrations are excited. The purpose of this work was to analyze the effect of temperature shock on the characteristics of the plate’s own vibrations. Specifying the parameters of natural vibrations and considering temperature shock make it possible to model the vibration process more adequately. The simulation parameters simulate the conditions of the space environment. Therefore, the results of this study can be applied to the study of thermal vibrations in solar panels and other large elastic elements of spacecraft.
