Abstract

Design, analysis and Optimization of launch pad structure for launch vehicle which starts from a ship are purposes of this article. In this article a finite elements code was written in MATLAB software that is used for calculation of stresses and nodal displacements. The loads which missile, ship and wind apply to the launch pad structure for launch vehicle have been considered. Simulated Annealing (SA) algorithm was used for Optimization of design. So a SA code was written in MATLAB. This code uses the finite elements method for calculation of stresses and the displacements. In this article, the objective function is set to minimize the weight of the structure. The constraints imposed to the analysis are the allowable stress and the displacement which are respectively 153. 3 Mpa and 3 mm. The design variables are Specification of cross sections which are thickness and external diameter. By calculating the applied loads to the structure and appropriate modeling, stresses and nodal displacements were obtained as results of finite elements code and by using Simulated Annealing algorithm, cross sectional areas were obtained.
