Abstract

The invention provides a forming method suitable for a main force bearing frame body of a satellite laser radar frame. The forming method comprises the following steps: S1, prepreg is laid on a mold,a flange is reserved, and a laid layer of a frame body overall part (1) is formed; S2, prepreg is laid on a thermal expansion mold core, after laying is completed, vacuumizing and pre-compacting are conducted, and a laid layer of a frame body cavity part (2) is formed; S3, prepreg is laid on the mold, and frame body reinforcing ribs (3) are prepared; and S4, the laid layer of the frame body cavitypart (2) is placed at the preset position, the prepared frame body reinforcing ribs (3) are sequentially placed into the main force bearing frame body cavity part (2), and a frame body cavity mechanism is constituted. According to the forming method suitable for the frame body of the satellite laser radar frame, the overall rigidity of a main force bearing frame and structural stability of a product are improved, and meanwhile, the requirement of weight reduction is met.

Description

technical field [0001] The invention relates to a molding method of a composite material structure, in particular to a molding method suitable for a main load-bearing frame of a satellite lidar frame. Background technique [0002] With the continuous progress and development of the aerospace industry, the accuracy requirements of satellites are becoming more and more stringent. At the same time, reducing the weight of satellite structures is one of the main means to improve satellite performance. The reduction of satellite structure weight not only greatly reduces the launch of satellites. cost, and can also provide space for the design of the payload. The satellite lidar frame requires high installation accuracy and structural stability. In order to ensure the imaging requirements, it is suitable for the satellite lidar frame. , the parallelism between benchmarks is better than 0.01mm, and the angle accuracy must be guaranteed to ±0.01. In order to ensure the imaging stab...
