Abstract

The invention relates to an aero-engine strength design method, which belongs to the field of aero-engine strength design. The method mainly comprises the steps of determining design input of aero-engine strength; carding professional design flows involved in strength design according to related data of aero-engine strength design; determining a design activity of typical intensity according to the carded design flow; designing a whole strength design process, matching strength design factors, judging the engineering adaptability of the strength design method, if the use requirements are met,obtaining a strength design result and process data, and if the use requirements are not met, adjusting typical design activities and iterating until the use requirements are met. According to the aero-engine design method, the strength design precision and efficiency can be improved, the required design process and design elements can be rapidly and accurately obtained, and unification of strength design standardization and flexibility is achieved.

Description

technical field [0001] The application belongs to the technical field of aero-engine strength design, in particular to an aero-engine strength design method. Background technique [0002] In recent years, with the rapid development of the aviation industry, the task of aeroengine design has become increasingly heavy, and the workload of simulation analysis of the structural strength design of the whole machine and components has also increased. With the development of strength specialty and the deepening of research, a relatively complete design system has been established, including strength design process, normative design elements, software tools and process database. To apply the design system to model strength design better, and at the same time improve the design system with the help of model development experience, the following problems need to be solved: [0003] 1) Improve the binding and operability of the process; [0004] 2) The strength design process needs t...
