Crane beam rapid estimation method based on mapping model with intermediate logic layer

Abstract

The invention belongs to the field of civil engineering, and discloses a crane beam rapid estimation method based on the mapping model with the intermediate logic layer. The method comprises the stepsof generating a crane beam design parameter database, carrying out classifying and encoding, establishing the mapping model with the intermediate logic layer, training an AI model, rapidly estimatinga crane beam to be solved and analyzing the influence of parameter change on economy. According to the estimation method provided by the invention, after the intermediate logic layer is added, the theoretical basis of the whole mapping model is stronger than that of a general input-output model, and the solving process can reflect a professional background; the model has expandability and can form a model in which a plurality of intermediate logic layers are connected in parallel; a neural network model with clear logic significance can be formed, the steel number, the braking form, the section size and the weight per unit length suitable for the crane beam can be rapidly evaluated, and the method can be used for analyzing the influence of parameter change on the crane beam design resultso as to optimize the crane beam from the perspective of economy.

Description

technical field [0001] The invention relates to the field of civil engineering, in particular to a method for quickly estimating a crane beam based on a mapping model with an intermediate logical layer. Background technique [0002] In industrial plants, overhead cranes are the most widely used due to their large capacity coverage and wide range of services. For steel structure workshops, when the span of the crane girder is ≤9m and the lifting capacity of the crane is ≤20t, the crane girder can be selected according to the national standard atlas with a suitable section specification of the crane girder; in large workshops (such as shipyard industrial workshops), the span of the crane is often longer Large (up to 42m), large lifting capacity (3t-200t), and non-standard crane applications are also common. At this time, it is necessary to design the crane girder through detailed calculation. Crane girder design is often calculated using the STS-crane girder design tool devel...

Problems solved by technology

However, since the solution of the mapping relationship is a purely mathematical method, it is generally difficult to interpret the obtained mapping model from the perspective of professional theory, and it is also difficult to reflect the logical relationship from input to output.
