Non-limiting embodiments according to the present invention are described in detail below with reference to the accompanying drawings.
Fig. 1 is a schematic diagram of an overall architecture of a skylight environment simulation system 100, according to a non-limiting embodiment of the present invention.
As shown, the sky light environment simulation system 100 may include an infrastructure 10, an optical system 20, a mechanical system 30, a control system 40, and an electrical system 50. These subsystems have a modular design and can be matched to each other to achieve the desired sky environment simulation function.
Fig. 2 is a schematic diagram of an infrastructure 10 of a sky-light environment simulation system 100, according to a non-limiting embodiment of the present invention.
The base structure 10 may provide a closed physical structure for the sky light environment simulation system 100, and a main supporting structure is provided, so that a relatively closed, complete and independent test space is formed after the systems are integrated.
As shown in fig. 2 and as a non-limiting example, chassis 10 may include a body support structure 11, a structured floor 12, and a door zone structure 13. The body support structure 11, the structured terrace 12 and the door zone structure 13 can be fitted together to enclose a hollow space for accommodating a subject, and the door zone structure 13 can be opened and closed for the subject (e.g., a cockpit structure of an aircraft, etc.) to enter and exit the skylight environment simulation system 100.
Fig. 3 is a schematic view of the main body support structure 11 of the sky-light environment simulation system 100 according to a non-limiting embodiment of the present invention.
As shown, the main body support structure 11 may have a split-joint web structure, such as a hemispherical web steel structure, including a hemispherical upper portion 11A and a lower portion 11B having straight wall sections, and including support columns and short cross beams 11D disposed between the support columns 11C.
Preferably, the main body support structure 11 can be formed by integrally formed support columns 11C and short beams 11D between the support columns 11C.
In this embodiment, the main body support structure 11 is made of steel, however, the main body support structure 11 may be made of various metal or non-metal materials, for example, may include various profile structures, as long as the strength thereof can satisfy the predetermined rigidity requirement.
Typically, the main body support structure 11 may be externally covered with a skin, which may be provided in a grid cell enclosed by the support columns 11C and the short beam 11D. The skin may comprise various sheet-like materials, such as various composite material sheets, metal sheets, and the like.

As shown, the door zone structure 13 may include first doors 131, e.g., 2 first doors 131, that move relative to each other to open or close. The first door 131 may be, for example, hung on a door rail 132 provided on the main body support structure 11 to be driven by a corresponding actuator to slide along the door rail 132 to serve as an entrance/exit passage for the subject to enter/exit the sky light environment simulation system 100.
The opening of the door zone structure 13 may be, for example, not less than 9m (width) × 8m (height), and preferably, the door zone may have a double-layer structure in which the outer layer is a double-leaf sliding door.

It should be understood that the door zone structure 13 shown above in connection with fig. 5 is merely illustrative and that a person skilled in the art may envisage other structural forms and dimensions.
