Problems solved by technology

These measurement methods either collect a huge amount of data, and the data processing is complicated, so it is difficult to accurately obtain the shape information of the sailboard, resulting in inaccurate shape perception, or due to the limitation of the detection data method and the required equipment structure, it cannot be well adapted to the space. weather environment, it is difficult to apply to practical engineering

Embodiment Construction

[0052] An implementation example of the present invention is to perform structural shape perception and visual reconstruction on a simulated space flexible sailboard model in the form of a simply supported fixed cantilever beam at one end.

[0053] The space flexible sailboard structure form perception and visualization reconstruction device adopts the structure shown in Figure 1, including a simulated space flexible sailboard structure ①, a discretely distributed fiber Bragg grating sensor ②, a fiber Bragg grating network signal analyzer ③, a Algorithm operation and graphics processing computer ④ and a monitor ⑤, the physical structure of the device is shown in Figure 8.

[0054] In this example, an epoxy resin board is used as a physical model for simulating the space flexible sailboard structure ①. This composite polymer structure has high strength, light weight and good flexibility characteristics, can maintain good surface shape characteristics in static state, and can pr...

Abstract

A method for visualizing structure form of space flexible boardsail includes implanting discrete Brag fiber grating sensor network in distribution mode on surface of boardsail structure, detecting structure strain information at each measurement point, carrying out data treatment on detected information in computer and utilizing pattern treatment technique of computer to carry out accurate 3-D real time restructuring and display of deformation state at simulated space flexible boardsail structure on computer. The device used for realizing said method is also disclosed.

Description

technical field [0001] The invention relates to a method and device for shape perception and visualization of a space flexible board curved surface, in particular to a method and device for shape perception and visualization of a space flexible sailboard model structure. Background technique [0002] Today's major countries in the world are competing to develop the aerospace industry and are actively exploring deeper space, which leads to the increasing size and complexity of spacecraft. Since the main energy of the spacecraft comes from the silicon photocells fixed on the surface of the solar panels, the energy provided to the spacecraft is realized by converting solar energy into electrical energy, so the increasing energy demand leads to the increasing size and extension of the solar panels. It is not uncommon to see solar panels with a length of tens of meters, so the requirements for the stability of the operation of the panel structure and topological conformity are be...
