ABSTRACT

We consider a mathematical model for investigation of surface deformations of the main mirror of a space telescope rested on the system of points supports. We use the boundary element method for solution the problem. We propose a non-standard scheme for construction of the resolving equations system. The developed algorithms are realized as proper software environment. One can apply the constructed model for finding the strain field of a mirror being subjected to the various actions of static loads and rested on the point supports with different variants of arrangement.
