扑翼飞行器是基于鸟类仿生学理论衍生出的新型无人飞行器,主要通过机翼周期性上下扑动来提供飞行器所需的升力和推力,在军用和民用飞行器领域均有广阔的应用前景。扑翼飞行器气动力测量作为样机气动性测试的重要手段,多维气动力的准确测量可为新型扑翼飞行器设计优化和飞控品质的提高提供试验数据支持。本文介绍了一种新型组合式多维小量程测力平台,可实现扑翼飞行器六维气动力和气动力矩的测量。考虑到扑翼飞行器机翼上下扑动过程动态测力需求,应用Ansys Workbench有限元分析软件对测力平台进行了模态分析和频响分析,获得在工作频率下的频率响应,仿真结果表明测力平台的振动特性满足设计要求。
The flapping-wing aircraft is a new type of UAV derived from the theory of bird bionics. The flapping-wing aircraft provides the required lift and thrust for the aircraft mainly through periodic flutter of the wings, and has broad application prospects in both the military and civilian aircraft fields. The aerodynamic measurement of flapping-wing vehicle As an important means of aerodynamic testing of prototype, the accurate measurement of multi-dimensional aerodynamic force can provide experimental data support for the design optimization of flapping-wing aircraft and the improvement of flight control quality. This paper introduces a new combined multi-dimensional small-scale force measuring platform that can realize the six-dimensional aerodynamic and aerodynamic torque measurement of flapping-wing aircraft. Taking into account the demand of dynamic force measurement of flapping-wing aircraft flutter up and down, Ansys Workbench finite element analysis software was used to analyze the modal and frequency response of the force-measuring platform to obtain the frequency response at the working frequency. The simulation results show that Vibration platform to meet the design requirements.
