摘　　要：分析了影响光电告警设备轴系精度的各种因素,对某型复合式告警设备的轴系精度进行了研究分析。提出将理论分析与实验校核相结合的研究方法应用于一种复合式车载小型导弹告警跟踪设备的轴系分析研究中。重点解决了常规分析中仅对实轴系误差的径向调平与晃动误差Δc、轴向窜动误差Δs及回转运动时的主轴角运动误差Δr进行分析的问题,提出将系统中的视轴误差(照准差Δp和视轴晃动误差)精度也作为轴系精度理论分析模型参数的观点。此方案在某型在研告警跟踪设备的轴系设计与分析中进行了理论与实验的对比研究,其最大误差可控制在3.2″以下,完全满足系统轴系精度设计要求。该轴系精度分析模型可用于其他小型光电跟踪设备中。It analyzed all kinds of factors which effected the photoelectricity equipment axis accuracy,and studied the axis accuracy of a complex warning system,and put forward that the axis accuracy of a complex missile warning system using theory analysis and experiment.In general analysis it just analyzed the real shafting error such as radial flat and shaking error Δc,axis moving error Δs,and the principal axis moving error Δr when the system was moving.It put forward a point of view using the watching axis error(collimate error Δp and watching axis shaking error)as the parameter of the axis accuracy error theory analysis mode,and did some contrast study between theory and experiment to axis design and analysis of a designing warning and track equipment.The biggest error is can be controlled 3.2″,of course this system’s axis error can satisfy the design request.The axis accuracy analysis mode can be used to other opto-track system.
