General design method based on parameter fine tuning in industrial machinery design scene

Abstract

The invention discloses a general design method based on parameter fine tuning in an industrial machinery design scene, which comprises the following steps: classifying historical design schemes in a database, and carrying out concept abstraction based on the classified design schemes; binding the drivable parameters of the parts in the abstract design scheme with the part parameter feature data in the historical design scheme; matching an abstract design scheme for the existing design scene; placing the abstract design scheme in an existing design scene; constructing a predicted value based on the drivable parameter, constructing a loss function of the predicted value and a target value based on the target value of the existing design scene, and transforming the predicted value based on the part drivable parameter of the abstract design model to obtain a gradient value of the loss function; solving the optimal descending direction of the loss function, updating the drivable parameter value of the abstract design scheme, repeatedly iterating until the minimum loss value, and taking the drivable parameter value at the moment as the optimal mechanical design scheme of the abstract design model in the current scene.

Description

technical field [0001] The invention relates to the technical field of mechanical design, in particular to a general design method based on parameter fine-tuning in the industrial mechanical design scene. Background technique [0002] There are a large number of historical mechanical design schemes in the field of mechanical design. When a design engineer gets a design scene, he often tends to find a set of similar or partially satisfying design requirements from the historical mechanical design schemes to modify it. The general method is to manually adjust the size parameters of the design scheme to meet the design requirements through the design engineer, or sort out the rule generation logic of this set of schemes, and generate the final design that meets the current design requirements by writing some program rules for this type of scheme. plan. Such methods have at least the following disadvantages: [0003] It involves a lot of modification work, and the versatility ...
