Forming method of high-precision satellite sensor beam

Abstract

The invention provides a forming method for a high-precision satellite sensor beam. The forming method comprises the following steps of firstly, preparing reinforcing ribs; secondly, conducting overall laying after laying is carried out on soft mold cores where the beam and satellite sensor heads are installed; thirdly, placing the prepared reinforcing ribs on a product, then conducting overall laying and forming spliced pieces; fourthly, putting the spliced pieces in a mold frame according to a tool drawing and assembling the spliced pieces in the mold frame in place; fifthly, disposing the product after subjected to mold assembly on a hot pressing machine, and carrying out heating, pressurizing and precuring; sixthly, taking off the mold frame, the spliced pieces and the soft mold cores and taking out a blank; seventhly, putting the blank after flashes and burrs are cleaned up in a drying oven for post processing. The forming method has the following advantages that a forming mode of satellite sensor beam and reinforcing rib integrated procuring and post-processing is adopted, the technological process is simple and convenient, and the produced multi-rib complex satellite sensor beam is high in strength and accurate in installation face angle and meets the requirement of weight loss at the same time. The forming quality is stable through detection of an ultrasonic harmless flaw detector.

Description

technical field [0001] The invention relates to a molding method of a composite material structure, in particular to a molding method of a beam of a satellite sensor. Background technique [0002] The star sensor is a satellite three-axis attitude measurement device, and the star sensor beam is a supporting mounting bracket designed according to the installation angle of the star sensor, which is a key part of the satellite assembly parts. Satellites are generally equipped with three or more star sensors. In order to reduce the effective installation area, reduce the relative relationship between multiple star sensors, and improve the satellite attitude determination accuracy and payload positioning accuracy, more and more The product is designed as an integral bracket that can install multiple star sensors at the same time. Usually, this kind of star-sensitive bracket with multiple mounting surfaces is prepared by molding the bracket head, the bracket body and the reinforc...
