Abstract

The invention provides a modeling method and device of a spinning machine. The modeling method includes obtaining a CAD (computer-aided design) model through topological optimization, and drawing structures of a plurality of parts in the spinning machine and a hollow rib grid structure of the spinning machine in the CAD model; converting the CAD model into a parameterized CAE (computer aided engineering) surface-structured model; establishing a finite element parametric model of the spinning machine according to the parameterized CAE surface-structured model; subjecting the finite element parametric model to parameter optimization to obtain an optimized spinning machine structure. By the modeling method, the spinning machine can be designed through a parameterized finite element, and optimization efficiency and product performance of the spinning machine are improved.

Description

technical field [0001] The invention relates to the mechanical field, in particular to a modeling method and device for a spinning machine. Background technique [0002] The essence of the parametric design method is a product description method based on constraints. Compared with the traditional design method, the biggest difference between the parametric design method is that the parametric design method stores the product design process through the product description method based on constraints, so Through the parametric design method, a family can be designed instead of a single product. In addition, parametric design can partially modify or change some constraint parameters without redesigning the whole process of product design. The finite element method is the most commonly used computer-aided engineering (Computer Aided Engineering, CAE) analysis method, and it is the most important simulation tool in the virtual manufacturing process. The finite element calculati...
