摘要
为解决无人机等低空飞行设备在公共场所中的安全隐患问题,采用双方位加俯仰的结构形式,设计了一种便携式车载高精度小目标搜跟一体三轴转台。在保证精度指标的基础上,建立这一车载高精度搜跟一体三轴转台的三维实体模型,运用有限元数值方法对三维实体模型进行静力学分析,确认结构强度和刚度均满足设计要求。对这一车载高精度搜跟一体三轴转台进行模态分析,得到前6阶模态的固有频率和振型,并进行随机振动响应分析。分析结果表明,这一车载高精度搜跟一体三轴转台的结构设计合理,满足使用要求。
In order to solve the potential safety hazards of low-altitude flying equipment such as unmanned aerial vehicle in public places,a portable vehicle-mounted high-precision small target search/track integrated three-axis turntable was designed with a dual-orientation plus pitching structural configuration.On the basis of ensuring the accuracy indicator,a three-dimensional solid model of this vehicle-mounted high-precision search/track integrated three-axis turntable was established,and the three-dimensional solid model was statically analyzed using finite element numerical method to confirm that the structural strength and rigidity meet the design requirements.The modal analysis was performed on this vehicle-mounted high-precision search/track integrated three-axis turntable,and the natural frequencies and vibration modes of the first 6 order modes ware obtained,and random vibration response analysis was performed.The analysis results show that the structural design of this vehicle-mounted high-precision search/track integrated three-axis turntable is reasonable and meets the operating requirements.
