Design of plant protection unmanned aerial vehicles: Quantitative research and virtual simulation

To enhance people's perceptions of agricultural machinery and elevate agricultural equipment to a high-end status, this paper proposes a product design evaluation process based on quantitative theory and virtual simulation technology. First, an "imagery–part library–virtual simulation" product design model is established through the integration of Kansei engineering and artificial intelligence (AI) drawing technology to construct a virtual part library. Assembly experiments are then conducted using a virtual simulation platform. Subsequently, a combined evaluation model, based on fuzzy comprehensive evaluation and behavioral experiments, is developed to evaluate and screen plant protection unmanned aerial vehicles (UAVs) from both the component and whole-system perspectives. Finally, the final scheme is simulated and optimized from the perspective of aerodynamics. This paper analyzes the modeling of plant protection UAVs from aesthetic and engineering viewpoints. It quantifies aesthetic requirements through various methods and integrates cutting-edge AI-assisted design and virtual simulation technology to optimize the initial product design process and consequently reduce the subjectivity of the product modeling process. The proposed methodology holds both theoretical and practical significance for the modeling design of agricultural machinery equipment.
