一体式保形位标器结构设计 摘要 伴随中国综合实力的飞速发展，国内军工业得到了空前的发展。同时随着制导技术的发展，导弹在现代军工业中也占有相当大的比例。现代实战数据表明，导弹在战争中发挥着越来越重要的作用。提高导弹的制导精度，是提高导弹打击效果最有效的手段。 导弹通常由弹头、弹体结构系统、动力装置推进系统和制导系统等四部分组成。按攻击活动目标的类型可分为：反坦克导弹、反舰导弹、反潜导弹、反飞机导弹、反弹道导弹导弹、反卫星导弹等。按飞行弹道可分为：主动段按预定弹道飞行，发动机关机后按自由抛物体轨迹飞行，再入段仍按自由抛物体轨迹飞行或机动飞行的弹道导弹等。其中位标器是导弹的重要组成部分，其性能直接影响导弹的性能,。位标器是导引头的核心组件，其设计制造水平决定了导引头的探测能力、视线稳定度和跟踪精度。位标器的主要设计思想是在确保跟踪尝跟踪速度、稳定精度和外形尺寸等前提下力求小型化、高可靠性和低成本。 本文设计的题目是一体式保形位标器结构设计。设计之初介绍了导弹及位标器的发展过程、现状及发展趋势，并分析其各自的特点。对各类导弹、位标器的总体结构进行了探讨及阐述。本文在查阅了国内外相关资料的前提下，对本次设计的课题进行了总体结构设计、在分析的同时对部件的结构设计、主要零部件的设计、计算及校核。利用AUTO CAD二维画图软件进行了零件的设计和装配，以满足使用要求。选择恰当的支承方式以及轴承选用等也是相当的重要。 本次完成了一体式保形位标器结构的设计，该位标器可提高飞行器性能，减少阻力减少热降面积，可提高内部空间利用率。有效提高性能。最终达到本次设计的综合训练的目的。 关键词：军工业、导弹、保形位标器、校核 ABSTRACT With the rapid developme
