Abstract

A method was developed to analyze thermally induced vibrations of large space structures based on the finite element method and modal analysis. Uncoupled differential equations of motion were obtained by utilizing the modal transformation and the orthogonality of the mode shapes with respect to the mass and stiffness matrices. The total dynamic response is the sum of the response components of every mode shape. Numerical calculations presented for the solar arrays on the Hubble Space Telescope agree well with the theoretical solution. Thermally induced vibrations of complex solar arrays can be analyzed to determine the solar array frequencies, mode shapes and thermally induced vibration behavior.
