Digital Application of Equipment System Test and Evaluation Based on Digital Twin and Parallel Experiment Theory
With the development of equipment systematization,traditional test with real equipment can not meet the requirements of Test and Evaluation(T&E),especially for complex equipment.As the main digital methods in current,digital twins and parallel experiments can support the digital application in the field of equipment Test and Evaluation.This paper makes a comparative analysis of the two digital technology means,extracts their technical connotation and characteristics,and then integrates them to explore the application mode,application time and application occasions in the field of equipment T&E.Taking the satellite for example,by constructing the digital architecture of equipment system T&E based on digital twin and parallel tests,the feasible digital application scheme is designed.The confidence and reliability of the digital model in the equipment system test and evaluation model library are verified through two typical test scenarios.Furthermore,it provides data support for the future on-orbit mission embodiment design and performance evaluation and provides an overall idea for the development of equipment system T&E.
