Embodiment

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

[0078] A) Carry out classification coding for each different part in each different part of each different agricultural machinery product in advance, determine respectively the classification coding number of each kind of part in each agricultural machinery product; Wherein, the classification coding number of each kind of part contains The shape information code segment indicating the shape feature of the part, the assembly information code segment used to indicate the part assembly method, and the specification information code segment used to indicate the shape specification of the part, the shape information code segment, the assembly information code segment and the specification information code segment The s...

example

[0125] Based on the above-mentioned embodiments, according to the method for evaluating the similarity of agricultural machinery parts based on system coding provided by the present invention, the rationality of the method of the present invention is verified by using a model calculation example. This calculation example lists three typical and representative calculation examples of component similarity.

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

[0127] Figure 5 with Image 6 They are the three-dimensional simulation diagram and exploded photo of the armrest frame mechanism of a micro tillage machine, which cons...

Abstract

The invention provides a method for evaluating the similarity of agricultural machinery parts based on system coding. By formulating a part coding method aimed at the characteristics of agricultural machinery products, and proposing according to the topological relationship of the corresponding parts, the shape similarity of parts and the similarity of parts assembly Calculate the similarity of parts with the judgment of similarity of part size, and then realize the calculation of similarity of parts, and set the threshold to evaluate the similarity. The effectiveness and reliability of the method for evaluating the similarity of agricultural machinery parts of the present invention are verified through the calculation of multiple example models. Through the evaluation of component similarity, the components of the module library can be integrated, so as to leave components with more reasonable design and higher reusability, eliminate redundant or relatively unreasonable components, and facilitate the management of components in the product platform; It can also provide more and better alternatives for product configuration and enhance the innovative design of products.

Description

technical field [0001] The invention relates to the technical field of similarity evaluation of mechanical parts, in particular, a method for evaluating the similarity of agricultural machinery parts based on system coding is designed. Background technique [0002] A product family refers to a collection of a series of similar products, and each individual product in the product family has the same or similar components or functional modules. The modular product platform is shared by product families and is a collection of common, reusable modules and associated objects. In practical 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 the product, or to enhance the versatility of components within the product platform , it is necessary to compare and select two highly similar parts in the module library, so as to leave more practical and reliabl...
