Simulation Analysis of Airfoil Deformation of Agricultural UAV under Airflow Disturbance Based on ANSYS

摘要

In order to meet the needs of analysis and correction of measurement errors in airborne distributed POS systems, the simulation analysis method of airfoil deformation of agricultural unmanned aerial vehicle (UAV) based on ANSYS, which is carried out under airflow disturbance, is discussed in this paper. The Pro/E virtual model data is imported into the ANSYS STRUCTURAL module, and the airfoil structure and material property parameters are set; the atmospheric turbulence model based on the k-epsilon model is established by using the ANSYS Fluent fluid dynamics module, the fluid boundary conditions are set in combination with the airfoil virtual structure, then the surface pressure value of the airfoil is obtained by finite element analysis; finally, combining the virtual structure and material information of the airfoil, the deformation parameters of different points of the airfoil relative to the fixed end can be simulated and solved. The method and result are studied in this paper to provide a reference for the analysis of the influence of airflow disturbance on the airfoil morphology and the evaluation of the POS measurement error.
