Automatic optimization design method and system for pipeline support hanger

The invention relates to an automatic optimization design method and system for a pipeline support hanger. An automatic optimization design program database is constructed by a support profile type, a support strength calculation and limit value rule, a support rigidity calculation and limit value rule and a support optimization method; the support profile type, the support strength, the support rigidity and the whole support profile using amount are used as parameters of optimization design, according to an automatic optimization design process, automatic optimization design is conducted on an initial scheme of the support hanger, profiles of all parts of the support hanger are automatically selected, and on the premise that the scheme obtained through optimization design meets the strength and the rigidity, the design efficiency is greatly improved. And the material consumption of the support and hanger sectional materials is minimum. The method can be applied to automatic optimization design of nuclear isl
