摘要
针对石化管道巡检无人机所搭载的云台在强度刚度、结构稳定性等方面要求高的问题,设计了一种以多旋翼无人机为平台的三轴云台。根据工况要求设计了无人机的机体,同时对云台的结构组成、结构设计、材料选择、所受载荷等方面进行分析,运用UG NX软件的高级仿真模块建立了云台的有限元模型,解算该模型,分析静力学应力应变及动力学四阶模态振型。为验证设计,制作了云台样机,并挂载在无人机上进行测试。结果表明:该云台在强度刚度、减振性能上满足系统稳定性要求,设计合理可行。
Aiming at the high requirements of strength,rigidity and structural stability of platform carried by UAV of petrochemical pipeline inspection,triaxial platform for multi-rotor UAV is designed.The airframe of UAV is designed according to the working condition.The structural composition,structural design,material selection and load of the platform are analyzed.The finite element model of the platform is established by using the advanced simulation module of UG NX software.The model is solved and the static stress-strain analysis and the fourth-order mode vibration mode of the dynamics are analyzed.In order to verify the design,the prototype of the platform is made and mounted on the UAV for testing.The results show that the platform meets the stability requirements of the system in terms of strength,stiffness and vibration damping performance.It’s proved that the design is reasonable and feasible.
