Forming method of spatial curved surface protective plate with internal and external bidirectional stiffener

Abstract

The invention discloses a forming method of a spatial curved surface protective plate with internal and external bidirectional stiffener. Firstly the model of the spatial curved surface protective plate is accurately expanded into a two-dimensional plane model, a corresponding CAD model is obtained, and a panel is processed according to the two-dimensional plane model, and a two-dimensional planepanel after the spatial protective plate being expanded and modified is obtained, then a forming die for processing one side stiffener is designed and manufactured, the plane panel is formed by singlepoint plastic processing, and the plane panel including single surface qualified stiffener is obtained, then the plane panel with the formed single surface stiffener is turned over and placed on theforming die for processing the other side stiffener, single point plastic forming is conducted, and an aluminum alloy spatial curved surface protective plate with the internal and external bidirectional stiffener is obtained, finally, a rubber plate is filled with the inner and outer stiffeners of the curved surface protective plate for equal thickness treatment and fixedly sealing, the plane panel is rolled and bended by a three-axis rolling and bending machine, then trimming and polishing are conducted, and thus forming of the spatial curved surface protective plate with the internal and external bidirectional stiffener is completed.

Description

Technical field [0001] The invention relates to the technical field of forming technology for a walker protective structure, in particular to a method for forming a space curved protective plate with inner and outer bidirectional reinforcing ribs. Background technique [0002] With the development of aerospace industry, the space debris environment is deteriorating day by day, and the threat of space debris to orbiting spacecraft is becoming more and more serious. The design of space debris protection for spacecraft has become a necessity of the times and an inevitable trend of future development. The development of a series of space activities such as manned spaceflight and space rendezvous and docking in China has proposed effective space debris protection design for spacecraft. Urgent request. [0003] The relative impact velocity between space debris and spacecraft is approximately in the range of 1km / s to 16km / s. The focus of space debris protection is on tiny debris with a v...
