Description
技术领域technical field
本发明属于航天器总装过程测量工装,具体来说,涉及一种航天器上太阳帆板驱动装置(SADA,solar array drive assembly)支架用的绝缘测量工装。The invention belongs to a measurement tool for the assembly process of a spacecraft, and in particular relates to an insulation measurement tool for a solar array drive assembly (SADA, solar array drive assembly) support on a spacecraft.
背景技术Background technique
为实现SADA的浮地要求,避免SADA与SADA支架安装面接触导通,采用在SADA支架上粘贴聚酰亚胺绝缘膜,从而实现SADA与支架之间的隔离。通常,制作材料选用100m的聚酰亚胺膜,裁剪的绝缘膜不能存有裂纹和缺口。通常,SADA支架上聚酰亚胺膜的结构如图1所示,其中,SADA支架圆周上的聚酰亚胺膜具有11个孔,其中在下半圆周上,7个孔每隔30度设置,在上半圆周上,4个孔对称设置,下方的两个孔与水平直径圆周位置的两个孔分别成30度,上方的两个孔与垂直直径圆周位置分别成20度。In order to realize the floating requirements of SADA and avoid the contact and conduction between SADA and SADA bracket mounting surface, polyimide insulating film is pasted on SADA bracket to realize the isolation between SADA and bracket. Usually, 100m polyimide film is used as the production material, and the cut insulating film cannot have cracks and gaps. Generally, the structure of the polyimide film on the SADA stent is shown in Figure 1, wherein the polyimide film on the circumference of the SADA stent has 11 holes, wherein on the lower half circle, 7 holes are arranged every 30 degrees, On the upper half circle, 4 holes are arranged symmetrically, the two holes at the bottom are respectively at 30 degrees to the two holes at the horizontal diameter circle position, and the two upper holes are at 20 degrees to the vertical diameter circle position respectively.
在航天器总装过程中,需对SADA支架上聚酰亚胺膜与SADA支架之间的绝缘阻值进行测量,要求20个以上的测量点阻值不小于1M,一般采取用普通万用表所使的原装标准型号表笔进行测量,但是,原测量方法在下列弊端:In the process of spacecraft assembly, it is necessary to measure the insulation resistance between the polyimide film on the SADA bracket and the SADA bracket. It is required that the resistance value of more than 20 measurement points should not be less than 1M. Generally, an ordinary multimeter is used. The original standard model test pen is used for measurement, but the original measurement method has the following disadvantages:
1)由于SADA安装是面接触,采用选点测量的方法无法对整个安装面进行检查,存在覆盖性差的特点,无法保证SADA绝缘膜的安装质量,由于SADA浮地阻值具有严格要求,若此绝缘效果不满足要求,会直接导致后续SADA安装时浮地阻值不满足要求,造成SADA反复拆装的风险;1) Since the SADA installation is in surface contact, the entire installation surface cannot be inspected by the method of point selection measurement, which has the characteristics of poor coverage and cannot guarantee the installation quality of the SADA insulating film. Since the SADA floating resistance has strict requirements, if this If the insulation effect does not meet the requirements, it will directly cause the floating resistance value of the subsequent SADA installation to fail to meet the requirements, resulting in the risk of repeated disassembly and assembly of the SADA;
2)测量时采用万用表表笔直接接触绝缘膜测量,金属表笔在20余次的反复测量过程中容易对绝缘膜造成损伤,从而增加后续SADA安装工作的风险;2) When measuring, use a multimeter pen to directly contact the insulating film for measurement. The metal pen is likely to damage the insulating film during more than 20 repeated measurements, thereby increasing the risk of subsequent SADA installation work;
3)测量万用表表笔与触绝缘膜之间存在作用力,表笔在测量过程中于的测量角度与测量力度不能被量化控制,可能会造成绝缘膜与SADA支架产生相对位移,导致绝缘膜反复拆装的风险;3) There is a force between the test pen of the multimeter and the insulating film. The measurement angle and force of the test pen during the measurement process cannot be quantitatively controlled, which may cause relative displacement between the insulating film and the SADA bracket, resulting in repeated disassembly and assembly of the insulating film. risks of;
4)检验人员需对绝缘膜进行20余次的测量,重复性的测量工作费时的同时也增加了操作的风险。4) The inspectors need to measure the insulating film more than 20 times, and the repetitive measurement work is time-consuming and increases the risk of operation.
