Abstract

The invention discloses a method for controlling the manufacturing process of heavy parts of marine diesel engines based on digital twins, comprising the following steps: (1) creating a manufacturing service platform for heavy parts; (2) collecting real-time data; (3) establishing a digital twin model system ; (4) Quality prediction; (5) Synchronous execution and control of manufacturing process. The invention provides quality control for the manufacture of heavy parts of marine diesel engines. Based on the digital twin technology, the quality data of workpiece processing and manufacturing can be monitored dynamically, in real time and visualized; the digital twin model is used for real-time simulation to optimize the process parameters, and the optimized parameters To control the actual processing process; at the same time, the real mapping of information space and physical space is effectively used to realize the real-time and full-cycle control of the quality of critical parts in the manufacturing process and the stability of processing resources and equipment, which is very important for improving the quality of critical parts and resources. Utilization, and improving production efficiency are of great significance.

Description
