Abstract

The invention discloses an intelligent evaluation method for manufacturability of key parts of a marine diesel engine. The intelligent evaluation method comprises the following steps that 1, machiningcharacteristics of the key parts of the marine diesel engine are classified; 2, analyzing the MBD model, extracting geometric elements of processing characteristics and performing dimension reductionprocessing; 3, a machining feature classifier is constructed, and feature recognition is conducted through a comprehensive analysis method based on multi-angle image recognition; 4, extracting MBD model annotation information, and constructing a part information model and a machining feature information model; 5, collecting enterprise manufacturing resource information, and constructing a manufacturing resource information model; 6, collecting typical cases and adopting data mining technology for mining the machining feature structure design process rules of key parts of the marine diesel engine, and generating a structure manufacturability intelligent decision model. According to the invention, the problem of excessive human intervention factors of the current manufacturability evaluation system is solved, and the manufacturability evaluation content is perfected, so that the manufacturability evaluation mode is changed from regularization to intellectualization.

Description

Technical field [0001] The present invention relates to a manufacturability intelligent evaluation method of a marine diesel engine key member, in particular, to a manufacturability intelligent evaluation method of marine diesel engines with regularity to intelligently transforming a manufacturability. Background technique [0002] As a commonly used important part in the mechanical field, the diesel offsetting process is complex and the accuracy requires high. During the production process, the design department and manufacturing department often lack information exchange, the former rarely considers the process, manufacturing, assembly, detection, etc. of the downstream stage, and is difficult to manufacture or even manufacturing the design structure thereby produced. In this case, the introduction of manufacturing evaluation techniques for process analysis and manufacturing rationality evaluation, can determine the rationality of part design from the manufacturing perspective ...
