Abstract

The invention provides a modeling method for the process reliability of a marine diesel engine body machining process. The modeling method is used for accurately evaluating the process reliability ofthe marine diesel engine body machining process. The engine body serves as the assembly basis of parts, components and parts of the marine diesel engine, and the machining quality of the engine body has direct influence on assembly and use of the marine diesel engine. The research on the reliability of the marine diesel engine body processing technology is of great significance for improving the diesel engine quality. Based on this, the engine body machining process flow is analyzed, the engine body machining key procedures are determined, the engine body machining key characteristics are determined through PFMECA analysis, and a marine diesel engine body machining process reliability model considering erroneous judgment is established. The method can effectively evaluate the machining process reliability of the marine diesel engine body, improve the machining quality and reduce the production cost.

Description

Technical field [0001] The invention belongs to the technical field of production process control, and specifically relates to a modeling method for the process reliability of the marine diesel engine body processing process Background technique [0002] Marine diesel engines must meet strict reliability requirements due to the particularity of their operating environment. Reasonably designed diesel engine parts need to be processed and manufactured before they can be put into use. Ensuring the process reliability of parts processing is of great significance to improving the quality of diesel engines. The fuselage is the basis for the assembly of marine diesel engine parts, components and components, and its processing quality has a direct impact on the assembly and use of marine diesel engines. The fuselage of marine diesel engines is large in size, complex in structure, and numerous in features, and the requirements on the processing quality of the fuselage are extremely stric...
