Embodiment

[0077] This embodiment adopts the method for evaluating the similarity of agricultural machinery components based on the system coding of the present invention to perform the similarity evaluation of agricultural machinery components, which specifically includes the following steps:

[0078] A) Preliminarily classify and code different parts in different parts of different agricultural machinery products, and respectively determine the classification code number of each part in each agricultural machinery product; among them, the classification code number of each part contains The shape information code segment indicating the shape feature of the part, the assembly information code segment for indicating the assembly mode of the part, and the specification information code segment for indicating the shape specification of the part, the shape information code segment, the assembly information code segment and the specification information code The segments are respectively in the ...

example

[0125] Based on the above-mentioned embodiments, the method for evaluating the similarity of agricultural machinery components based on system coding provided by the present invention will use model calculation examples to verify the rationality of the method of the present invention. This calculation example lists 3 typical and representative component similarity calculation examples.

[0126] Agricultural machinery is divided into many product families, such as tillers, harvesters, and handlers. Each family is subdivided into many series. Different series have differences in structural composition and design concepts, and the same series of agricultural machinery There may be different styles, making them more or less different in appearance and partial design.

Abstract

The invention provides a method for evaluating the similarity of agricultural machinery parts based on system coding. Through a component coding method formulated for characteristics of agricultural machinery products and a proposed topological relationship according to corresponding parts, component similarity calculation is performed on the shape similarity of components, the component assemblysimilarity and the component shape similarity determination, and then the similarity calculation of the parts is achieved, and a threshold is set to evaluate the similarity. Through multiple instancemodel calculations, the effectiveness and reliability of the method for evaluating the similarity of the agricultural machinery parts according to the invention have been verified. Through the evaluation of the similarity of the parts, the parts of a module library can be integrated, so that the parts with a more reasonable design and higher reusability are kept and redundant or relatively unreasonably designed parts are eliminated, and the management of the parts in a product platform is facilitated. The method can also provide more and better alternative schemes for product configuration andenhance the innovative design of products.

Description

Technical field [0001] The invention relates to the technical field of similarity evaluation of mechanical parts, in particular to design a method for evaluating the similarity of agricultural machinery parts based on system coding. Background technique [0002] Product family refers to the collection of a series of similar products. Each product in the product family has the same or similar components or functional modules. The modular product platform is shared by the product family and is a collection of a series of universal, reusable modules and associated objects. In actual applications, newly designed components are often added to the product platform to provide more and better alternatives for product configuration, to enhance the innovative design of products, or to enhance the versatility of components in the product platform , It is necessary to compare and select two highly similar components in the module library, so as to leave more practical and reliable component...
