| 英文摘要 | In order to solve the problem of high cost investment in the detection and debugging of complex optical machine functional components by Unmanned aerial vehicle (UAV), especially the aerial camera, a novel ground-based operational test bench is presented in this paper, which can realistically simulate the attitude of UAV and could be used for research of the control system. Based on the Lagrange's equations of motion, the exact dynamic equation of the flight simulation platform for ground-based operational test bench is derived. The structure is driven by Brushless DC motor (BLDCM) torque motor and simplifying the equations under conditions of practice, we derive the mathematical model. The static and dynamic characteristics were carried out by using the finite element theory to explain rationality of the ground-based operational test bench. Through modal analysis, the first six natural frequencies range is between 99.362Hz and 262.37Hz. The natural frequency of the first mode is much larger than the external excitation frequency. So, it is verified that the frequency response of the structure will not resonate. The ground-based operational test bench that is designed in this paper has the advantages of simple structure and low cost. |
