The invention discloses a force flow-oriented equipment lightweight bionic method and system. The bionic method comprises the steps that a biological database is acquired; a force transferring path visualization method is adopted to determine a main force transferring path of a to-be-tested structure; actual working condition characteristics and functional characteristics of the to-be-tested structure are acquired; the actual bearing type of the to-be-tested structure is determined according to the actual working condition characteristics and the functional characteristics; compared with the actual bearing type, historical bearing types higher than a similarity threshold are determined in the biological database; bionic prototypes corresponding to the historical bearing types are acquired;structural characteristics of the bionic prototypes are used as trunk sections to establish a bionic lightweight model; and bionic processing is performed on the to-be-tested structure according to the bionic lightweight model. By the adoption of the bionic method and system, the workload of selecting the biological prototypes can be lowered, and bionic efficiency is improved.
Description
technical field [0001] The invention relates to the field of structural bionic design, in particular to a force flow-guided lightweight bionic method and system for equipment. Background technique [0002] Lightweight is becoming an inevitable trend in the development of aerospace, automobile and other fields. Lightweight design can not only effectively solve problems such as energy consumption and environmental pollution, but also improve the mobility and operational stability of parts and components, which has great social and economic significance. value. After hundreds of millions of years of evolution, natural organisms have formed a variety of biological structures with excellent performance and refined structure, such as honeycomb, king lotus, fish bone, etc., all of which show excellent mechanical properties and light weight and high efficiency. Human beings have provided a lot of creative ideas to solve the lightweight equipment. Therefore, structural bionic desig...
