摘　　要：为提高精密光电设备的部署速度、实现快速部署应用,可采用不停车部署方案,即车辆行进过程中开展精密光电设备应用对高速飞行目标的观测、跟踪、干扰。为降低车辆行进过程中路面振动的影响,以某型载车及其光电设备为研究对象,分析行驶过程的振动响应。建立基于加速度均方根值的线振动和基于角度均方根值的角振动联合评价指标,综合评价设备安装平面处的激励扰动。基于分析结果可发现良好路面(A级和B级路面)下车辆会对精密光电设备产生约1~10 mrad的角振动激励,一般路面(C级路面)下车辆会对精密光电设备产生约5~20 mrad的角振动激励。从而可根据车辆行驶振动特性,为后续精密光电设备的设计、优化提供参考。The observation,tracking and interference of the target of the high-speed flying body need high fine optoelectronic equipment.To improve the deployment speed of precision optoelectronic equipment and achieve rapid deployment applications,a non-stop deployment plan can be adopted,which involves equipment application during vehicle movement.To reduce the impact of road surface vibration during vehicle travel,a certain type of vehicle and its optoelectronic equipment are taken as the research object to analyze the vibration response during the driving process.A joint evaluation method is based on the RMS of the acceleration and the RMS of the angle vibration.It can be used to evaluate the vibration at the basement of the fine optoelectronic equipment.Based on the analysis results,it can be found that under good road conditions(class A and B roads),precision optoelectronic equipment is subjected to angular vibration which around 1~10 mrad,and under general road conditions(class C road),precision optoelectronic equipment is subjected to angular vibration which around 5~20 mrad.The above indicators can be provided for the design and optimization of follow-up fine optoelectronic equipment.
