摘要
以某高精密搜跟一体光电设备为目标对象,根据该产品的技术指标要求,设计了一种高精密光电转台,对高精密光电转台样机进行装配与检测,确保轴系晃动误差值满足技术指标要求运用ANSYS软件对光电转台的三维模型进行模态分析,得出高精密光电转台的固有频率高于工作频率,不会产生共振现象.该高精密光电转台的实际使用效果表明该结构设计是成功的,对同类型转台类产品结构设计具有参考借鉴意义.
Abstract
Taking a certain high-precision tracking and search integrated photoelectric device as the target object,a high-precision opto-electronic turntable structure is designed according to the technical specification requirements of the product.By assembling and testing the precision opto-electronic turntable,it is ensured that the error of axis slos-hing meets the requirements of this structure.Using ANSYS software to conduct modal analysis on the three-dimen-sional model of the opto-electronic turntable and opto-electronic equipment,it is concluded that the intrinsic frequency of the high-precision opto-electronic turntable and opto-electronic equipment is higher than the operating frequency,and does not produce resonance phenomenon.The application of the opto-electronic turntable shows that the structure design of the high-precision opto-electronic turntable is successful and it can be used as a reference for the structure design of similar opto-electronic turntable.
