Multi-objective bionic design method for mechanical bearing components on basis of coupling element base hybrid integration

Abstract

The invention discloses a multi-objective bionic design method for mechanical bearing components on the basis of coupling element base hybrid integration. The multi-objective bionic design method includes steps of 1, analyzing similarity and contradictoriness of multi-objective design problems of the mechanical bearing components, selecting mutually contradictory design problems on the basis of analysis results and combining conflicts with one another to form a plurality of conflict units; 2, selecting biological prototypes for the optional conflict unit by means of structural bionics and extracting biological coupling element feature bases; 3, recombining and integrating all the extracted biological coupling element feature bases to obtain novel integrated coupling element bases with multiple dominant properties; 4, designing bionic structures of the mechanical bearing components on the basis of the novel integrated coupling element bases with the multiple dominant properties. The conflicts of the optional conflict unit can be solved by the biological prototypes. The multi-objective bionic design method has the advantages that the dominant properties of the diversified bionic prototypes can be complemented by the aid of the multi-objective bionic design method, accordingly, the mechanical bearing components with the multi-objective design problems can be designed, and the problem that only a single objective can be realized by structural bionic designs for existing mechanical bearing components is effectively solved.

Problems solved by technology

[0004] Although the research results of bionic structural design of mechanical bearing parts are relatively rich, the existing bionic design of bearing parts has a single goal, which can only realize the superior performance of a specific biological prototype, and lacks the multi-objective structural bionic design of mechanical bearing parts. Methods, taking the machine tool as an example, in the bionic design of machine tool columns, rams and other bearing parts, more attention is paid to reducing their mass and improving the stiffness performance in the bearing direction (compressive stiffness), while ignoring the stiffness performance in the direction of motion (bending resistance). Stiffness) requirements, etc.
