Abstract

Abstract: In order to solve the problems of long research and development cycles and low digitization in Exhaust Gas Recirculation (EGR) module development,a method for constructing a digital twin system for the EGR module was proposed. Firstly,accordingto the theoretical framework of digital twin model construction,an EGR module digital twin framework was designed from five aspects—physical model,digital model,virtual-to-real connection,state mapping,and twin services. Secondly,the construction of the digital twin model was achieved through three steps—solid three-dimensional modeling,front end scene building,and physical script mounting. Considering the characteristics of multi-source heterogeneity of twin data,a method for data acquisition and transmission was proposed,and visualization mapping was implemented.Finally,using the Unity 3D virtual engine as a platform,the above functions were integrated,and the EGR module digital twin system was developed. Experimental validation demonstrates the feasibility and effectiveness of the system,providing new insights for the digitized assistant design of EGR modules.
