Abstract

The invention discloses a control method for the manufacturing process of key parts of a marine diesel engine based on digital twin. The method comprises the following steps: (1) creating a manufacturing service platform for the key parts; (2) performing real-time data acquisition; (3) establishing a digital twin model system; (4) performing quality prediction; and (5) performing synchronous execution and control of the manufacturing process. Through quality control for key part manufacturing of the marine diesel engine, the quality data of workpiece processing and manufacturing based on a digital twin technology can be monitored dynamically and visually in real time. Process parameters are optimized by real-time simulation of a digital twin model, and an actual processing process is controlled with optimized parameters. Meanwhile, real mapping of an information space and a physical space is utilized effectively, and real-time and full-cycle management and control of the quality of thekey parts and the stability of processing resources and equipment in the manufacturing process are realized. The method is of great significance to improve the quality of the key parts and the utilization rate of resources, as well as to improve the production efficiency.
