Description

一种绷弦式半刚性基板框架的胶接装配工艺方法
本申请要求于2020年10月30日提交中国专利局、申请号为202011191862.9、申请名称为“一种绷弦式半刚性基板框架的胶接装配工艺方法”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本发明属于框架复合材料结构制造技术领域，尤其涉及一种绷弦式半刚性基板框架的胶接装配工艺方法。
背景技术
绷弦式半刚性基板是一个全新的结构形式，主要是为适应新一代超大容量静止轨道卫星平台的电源功率(≥25kw)需求、太阳翼减重需求和太阳翼高展开刚度需求。绷弦式半刚性基板主要由绷弦式半刚性基板框架、绷弦定位支架和Kevlar纤维编织绷弦组成，并且全部通过胶粘剂胶接装配成一体。绷弦式半刚性基板框架结构采用高模量碳纤维/氰酸酯树脂复合材料铺层成型的矩形管搭成主体框架，然后在主体框架上面绷一定张力值的高强度纤维绳，用于与太阳电池片的连接。为保证绷弦式半刚性基板的电池片在卫星发射阶段不与相邻基板的磕碰，对绷弦式半刚性基板框架整体平面度提出了高要求；为保证绷弦式半刚性基板收拢与展开精度，对绷弦式半刚性基板框架数个关键接口的孔位精度提出了高要求，对各零件胶接无应力装配提出了高要求。其中，单块绷弦式半刚性基板框架的外形尺寸约为(4050±1)mm×(2500±1)mm×32mm。绷弦式半刚性基板框架由30多根方管、30多件限位梁、9个压紧点接头、L型边框接头、20多件预埋件、200多件角片等零件胶接装配组成。
目前，常用的绷弦式半刚性基板框架胶接工艺方法是：将所有主梁、边框梁、加强梁、限位梁、压紧接头、边框接头、角盒、角片等零件全部齐套后放置于胶接装配工装上一次胶接装配成基板框架组件。该方法存在以下缺点：
1)由于零件种类数量均较多，胶接位置较多，受操作人员数量、胶接操作空间、胶粘剂适用期限制，较难实现快速同时一次胶接。
2)所有装配位置均须同步执行胶接固化加压过程，每个接口均存在各个方向的胶接装配关系，一次胶接无法保证加压均匀，易产生加压引起的横向位移，影响产品尺寸精度。
3)由于基板框架零件数量较多，各零件间装配关系复杂，多种装配关系耦合较多，一次胶接无法兼顾所有装配接口，易引起部分装配位置装配应力较大，导致产品使用过程中在 高低温环境下胶接不可靠。

具体实施方式
为使本发明的目的、技术方案和优点更加清楚，下面将结合附图对本发明公开的实施方式作进一步详细描述。
由于绷弦式半刚性基板中压紧点接头、铰链接头、边框接头、预埋件数量较多，各处尺寸位置精度要求高，且各尺寸互相联动，一处位置装配不准确将影响周围尺寸定位精度。针对以上特点，本发明公开了一种绷弦式半刚性基板框架的胶接装配工艺方法，采用缠碳丝法对各装配位置胶接间隙进行了控制，具体为将湿碳纤维丝均匀缠绕在各胶接接头的方管表面，保证接头与梁周向胶接间隙均匀一致，减小胶接应力的产生，提高框架产品尺寸精度。本发明解决了使用现有半刚性基板框架胶接装配工艺中胶接工期紧凑、装配精度差、存在较大装配应力等问题，使用该半刚性基板框架胶接装配工艺方法装配的半刚性基板框架产品各项性能指标符合设计及使用要求，并成功经历各项力学、热学试验考核，并顺利完成整翼与 整星的装配及力学性能试验。
