Description

The present invention relates to a simulator for simulating a representation when moving a vehicle. The invention further relates to a method for producing a simulator for simulating a representation when moving a vehicle.

Simulators for simulating a representation when moving or driving a vehicle have the function of training the user for the actual use of the vehicle. Examples of simulators are vehicle simulators, for example for car , For truck , for rail vehicles, for tracked vehicles, for ships, for submarines, for airplanes, for helicopters and the like. For example, a simulator can be equipped with a movement system in order to move a cabin of the simulator. Furthermore, simulators can have both an interior modeled on the vehicle and an exterior modeled on the vehicle. For example, high-quality and cost-intensive lightweight materials, such as fiber-reinforced plastic, can be used for this. For example, molds are required during production, into which mats are inserted by hand. In addition, there are high one-time costs for such forms, in particular because, because of their individuality, they require special productions and possibly manual work.

Furthermore, simulators, in particular a projection dome, can also comprise shaped walls which are illuminated with projectors and serve as a screen or projection surface. Mold walls of this type can have any size and can be formed from a high-quality lightweight construction material, such as, for example, fiber-reinforced plastic. For example, several molded walls are joined together, in particular screwed together, to form the projection dome.

Against this background, it is an object of the present invention to provide an improved simulator.

Accordingly, a simulator for simulating a visual representation when moving a vehicle is proposed. The simulator has a structural component which comprises a rigid lattice structure and a flexible material, the lattice structure being covered with the flexible material.

By using a covered lattice structure, a low weight can be achieved despite the high rigidity of the structural component, and the flexible material also prevents the structural component from being transparent and / or perforated and / or translucent. Furthermore, with the help of the flexible material, a targeted light transmission or coloring can be realized. The structural component is preferably backlit.

For example, the flexible material can be used to meet special requirements for a surface of the structural component. In particular, the flexible material can give the structural component a high-quality appearance. The flexible material can preferably be selected such that the structural component has specific reflection properties.

Advantageously, for example, a weight and cost-optimized element, in particular a design element, can thus be provided. This is particularly advantageous, for example, for small series production, since in particular it is not necessary to make expensive molds individually.

For example, the simulator is set up to display processes under realistic conditions. Moving the vehicle here means, for example, guiding or driving the vehicle. The vehicle is, for example, an airplane, a helicopter, a tank, a truck , on car , a crane, a ship or a submarine. The simulator can thus be designed, for example, as a driving simulator, aircraft simulator, helicopter simulator, truck simulator, car simulator, crane simulator, nautical simulator, ship simulator or submarine simulator. The simulator is preferably not the actual vehicle itself.

The lattice structure is formed, for example, from webs, between which spaces are formed. The lattice structure is preferably self-supporting and / or contouring and forms the supporting structure of the structural component. The lattice structure can be made from a lightweight material, in particular in the form of a framework. This can be carried out, for example, with the aid of a separation process, in particular by means of milling, cutting, punching and / or sawing. Alternatively or additionally, this is carried out using a 2D manufacturing process. The lattice structure can thus also be produced, for example, without the use of complex machines, such as a five-axis milling cutter, although a complex 3D lattice structure can nevertheless be formed with the aid of joining techniques. Flexible material means, in particular, a material which, when not connected to the lattice structure, has a low level of rigidity and can be rolled up, for example, into a roll. Preferably, all gaps in the lattice structure are covered with the flexible material and covered with it. The structural component and / or a molded component can thus be manufactured in a simple manner.

Covering means in particular that the lattice structure is at least partially covered by the material, a contact area being formed between the lattice structure and the material. The covering can take place, for example, with or without a material bond, in particular with the aid of an adhesive on the contact surface. In addition, a prestressing force can, for example, be applied to the material before the lattice structure is covered with the material. In particular, the material is permanently subjected to a tensile force or tensile forces when the lattice structure is covered. The material can thus have tensile stresses, for example. Alternatively or additionally, the flexible material can be ironed onto the lattice structure. Unevenness is preferably compensated for using heat or hot air.

According to one embodiment, the lattice structure is formed from a sandwich material and / or wood, in particular balsa wood, and / or metal, in particular aluminum, and / or fiber-reinforced plastic and / or paper and / or cardboard.

This has the advantage that a lightweight component with high strength can be provided. The lattice structure is preferably formed from laminated wood, in particular balsa wood, and / or metal, in particular aluminum, and / or fiber-reinforced plastic and / or paper and / or cardboard and / or foam, which are preferably joined to form a sandwich material.

According to a further embodiment, the flexible material is formed from a fabric, in particular a polyester fabric.

The flexible material is designed in particular as a film. For example, a coating, in particular a color coating, is applied to the flexible material or can be applied after covering. The coating can be carried out inside other than outside.

According to a further embodiment, the structural component is designed as an external or internal visual component of the simulator.

The structural component is preferably designed as the outer component of the simulator and thus forms the outer termination of the simulator. For example, the structural component is an outer lining or inner lining, in particular a cockpit lining, of the simulator. In particular, the structural component can be designed as any body part.

According to a further embodiment, the structural component comprises a surface for displaying a simulated visual representation.

For example, the structural component is thus designed as a display device. The surface is set up to be illuminated by a projector. In particular, the flexible material can be painted in order to create a projection surface with suitable reflective properties. The projection surface is preferably formed by means of a first coating and an adjacent surface by means of a second coating, the second coating having a different color than the first coating and being, for example, matt black. For example, the projection surface is designed as a concave polygon surface. The simulator preferably comprises an image correction device, in particular a so-called auto alignment, which is set up to correct a geometry of the image to be displayed, so that an undistorted image is produced for an observer.

According to a further embodiment, the structural component is curved or kinked.

For example, the structural component has an outer and / or inner contour which is designed as a cylinder, torus, spherical segment, ball or truncated cone.

According to a further embodiment, the structural component is designed as a half-timbered dome.

The truss dome is preferably designed as a sphere or spherical segment. The simulator is then preferably referred to as a projection dome. The ball or the ball segment preferably has an inner or outer radius between 2 and 5 m or 3 and 4 m, in particular 3.04 m or 3.56 m. The spherical segment extends, for example, horizontally over an angle of 240 ° or 300 ° and vertically over an angle of ± 60 ° or + 90 ° to -30 °. For example, the truss is designed as a crane simulator and / or hemisphere.

According to a further embodiment, the simulator comprises a movement system which is set up to move the structural component.

The movement system preferably comprises actuators, in particular hydraulic and / or electrical actuators.

According to a further embodiment, the lattice structure comprises webs which run in such a way that spaces are formed between the webs, at least some of the webs comprising openings to the spaces.

The openings are preferably used for laying electrical cables and / or light guides. Alternatively or additionally, light beams, in particular laser light beams, can run through the openings.

According to a further embodiment, the lattice structure is formed from segments which are added to the lattice structure, in particular plugged and / or screwed and / or glued.

The segments can advantageously be produced in a simple and, in particular, automated manner. By joining the segments, simple shapes or complex shapes can be realized despite the light and stable design.

According to a further embodiment, at least one of the segments tapers.

By joining several such segments, spherical structures can be easily generated.

Furthermore, a method for producing a simulator for simulating a visual representation when moving a vehicle, in particular as described above, is proposed. The method comprises the steps: a) providing a rigid lattice structure or a plurality of segments of the lattice structure, b) providing a flexible material, c) covering the lattice structure with the flexible material to form the structural component or covering individual segments of the plurality of segments with the flexible material and then joining the plurality of covered segments to form the structural component, and d) assembling the structural component to form the simulator.

According to a further embodiment, abutting edges between the segments are covered with a covering material, in particular a lacquer and / or foil, between steps c) and d).

According to a further embodiment, the plurality of segments is added to the lattice structure, in particular plugged and / or screwed and / or glued, before step a).

According to a further embodiment, the covering in step c) is carried out with the aid of a negative pressure and / or vacuum.

The embodiments and features described for the proposed simulator apply correspondingly to the proposed method and vice versa.
