Optimization And Application Of Production Quality Management System For Small Civil Uav

Civilian drones have developed rapidly.Small civilian drones account for more than60 % of the world's output value in China,and Guangdong accounts for more than 70 %of the country's output value.They have been widely used in agriculture,aerial photography,and electric power.However,at the present stage,the quality of civilian drone products is uneven,and many problems such as poor anti-jamming performance,low stability,and short operating time often occur.Although there is a certain degree of quality control and safety management in the production and manufacture of drones,drones have higher requirements for quality and safety management than other products and need to adopt stricter and more optimized quality management.Therefore,there is an urgent need to strengthen the production quality and safety management of UAV products,and this project is based on this premise.Firstly,this paper analyzes the quality control and safety flight status and quality management requirements of civilian UAVs,and optimizes the UAVs production process based on the current research on UAVs quality and safety management and the UAVs design,process,production and testing process.With reference to the international advanced QFD method,the key factors affecting quality and safety are optimized design and safety management,and the detailed optimization design of the quality centroid measurement method and the arm structure of the drone is emphasized.Then through SQL Server to establish a drone database,use Visual C++ as a software development tool and access and management of the database,and establish a drone data management system.Data management is mainly used in the management of a large number of drone production,design and flight data,and the flight test data is analyzed,and the factors affecting the quality and safety of drones are determined,and feedback back to the production and design links for optimization.Finally,the quality and safety management optimization verification is carried out,the drone optimization model is constructed by3 DS Max,and the model control is carried out by flight data.In the Unity environment,athree-dimensional visualization simulation system is developed and designed to display the flight status of drones recorded by flight data,evaluate the flight performance of drones,and simulate the flight status of drones in a physical environment.And through the actual flight,the optimized drone is tested in terms of suspension accuracy,flight time,maximum flight speed,flight reliability,etc.,and the comprehensive quality of the drone is tested to verify the feasibility of the drone quality and safety management system.Through the research of this paper,the production process,processing process,centroid measurement method and structure design of UAV are optimized.The efficiency of UAV data is improved,and the risks exposed and potential during the test can be discovered in a timely manner.The simulated flight reproduces the flight process of the drone,and the actual flight verifies the applicability of the quality and safety management system.The system has a high engineering application value in the research stage of UAV safety production,quality control,system design and simulation verification.
