Civil aircraft cockpit simulation platform based on mixed reality technology

To meet the needs of multi-scheme comparison and rapid optimization iteration in the early stage of civil aircraft cockpit design,a mixed reality simulation platform for civil aircraft cockpit design evaluation is developed.Based on the physical scene module,visualization module and operation logic module,the system framework of the simulation platform is designed.The techniques for high accurate virtual-physical fusion are developed,which build the digital twin models of cockpit hardware devices and pilots in an integrated mixed reality environment.To verify the feasibility and effectiveness of the mixed reality simulation platform,the same experiments are carried out on the physical cockpit simulation platform and the mixed reality cockpit simulation platform.The ergonomic analysis of the accessibility of the cockpit control components,cockpit layout rationality,instrument display visibility,and readability are carried out by combining subjective evaluation and objective measurement,and the test data are compared.The experimental results show that the test data of the mixed reality platform and the physical platform are consistent.The mixed reality simulation platform is effective for evaluating the cockpit design in early stage.
