The current quality prediction method for heavy parts of marine diesel engines has the following problems: the connection between virtual space and physical space is not close enough. At present, in the manufacturing process of heavy parts of marine diesel engines, the connection between virtual space and physical space is limited to the full 3D model based on MBD. Quality prediction in the manufacturing process of critical parts does not involve

The processing quality inspection lags behind. The inspection of the processing quality of the heavy parts of the marine diesel engine at the current stage is after the current process or product processing is completed. Therefore, the advantages of the quality prediction of the critical parts cannot be fully utilized, and quality disturbance factors can be eliminated in a timely manner. influences

Manufacturing information has not been utilized, and a large amount of manufacturing information has been generated in the production process of heavy parts of marine diesel engines, and this information has not been applied to the process of quality-critical processing of heavy parts
