Description

Technical Field

[0001] The present invention relates to the technical field of geomorphic simulation, and in particular, to a dynamic geomorphic simulation device. Background Art

[0002] Topographic boundary features include mountain valleys, plains, hills, and sea surface wave boundaries in a broad sense. Topographic and geomorphic simulation refers to the process of reproducing and studying complex topographic features through physical models or digital technologies, and is widely applied in environmental simulation, engineering design, scientific research, etc. In the field of civil engineering, accurately reproducing topographic and geomorphic features plays an important role in evaluating the disaster prevention safety of building structures. Especially in the field of structural wind engineering, topographic features, as complex underlying surfaces, will significantly affect the near-surface wind field, and further affect the distribution of wind loads borne by structures and their aerodynamic responses. Constructing a geomorphology-wind field coupling model is one of the core topics in the study of structural wind resistance performance. However, traditional topographic and geomorphic features are difficult to adjust timely along with the dynamic changes and historical vicissitudes of engineering sites, which greatly restricts the accurate simulation of the oncoming flow boundary conditions.

[0003] Existing topographic and geomorphic simulation devices mostly rely on a single drive system, and their expression methods are often simplified, single, and static, unable to achieve independent and fine dynamic adjustment. Due to the diversity and randomness of terrains in reality, existing simulation devices have obvious deficiencies in terms of flexibility, accuracy, and real-time dynamic adjustment, and are difficult to meet the high-precision reproduction of complex geomorphic features. Summary of the Invention

[0034] In order to enable those skilled in the art to better understand the technical solutions in the present invention, the following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0035] Please refer to Figures 1 - 3, an embodiment of the present application discloses a dynamic landform simulation device, including a support platform 1, a support frame 2, a guiding unit 3, a sliding unit 4, a simulation unit 5 and a driving unit 6. The support frame 2 is fixed on the support platform 1 and is used to provide positioning support for the guiding unit 3. The guiding unit 3 is fixed on the support frame 2, so that a space is formed between the guiding unit 3 and the support platform 1, and at the same time the guiding unit 3 is positioned. The sliding unit 4 includes a plurality of sliders 41 horizontally arranged in the guiding unit 3, and each slider 41 can move horizontally along the guiding unit 3. The simulation unit 5 is located in the space surrounded by the plurality of sliders 41. The simulation unit 5 includes a first elastic simulation member 51, a second elastic simulation member 52 and a skin 53 arranged in sequence from bottom to top. The first elastic simulation member 51 includes a plurality of elastic members, and both ends of each elastic member are respectively connected to two opposite sliders 41. The second elastic simulation member 52 is fixedly connected to the skin 53. The first elastic simulation member 51, the second elastic simulation member 52 and the skin 53 are stacked from bottom to top. The second elastic simulation member 52 is used to refine the surface shape and support the skin 53. Two opposite sliders 41 act simultaneously, so that the elastic members of the first elastic simulation member 51 move, thereby changing the distribution density of the elastic members in different regions, and further changing the support density of the second simulation elastic member 52, making the landform simulation more accurate and detailed. Several points can be selected around the skin 53 to realize the fixed connection with the second elastic simulation member 52. The driving unit 6 includes a plurality of vertical drivers 61. One end of each vertical driver 61 is fixed to the support platform 1, and the other end faces the elastic member and can move in the vertical direction to drive the elastic member to undergo elastic deformation.

[0036] The slider 41 can move horizontally in a straight line along the guiding unit 3, driving the elastic member to move horizontally, so as to change the distribution density of the elastic members in different regions, and further change the support density of the second simulation elastic member 52, so as to adjust the detailed simulation of the plane terrain. The vertical driver 61 can move in a straight line in the vertical direction, driving the elastic member to undergo elastic deformation, and the elastic member further drives the second simulation elastic member 52 to deform, so as to adjust the macroscopic elevation of the terrain. The two work together to enable the device to achieve three-dimensional fine simulation, and can generate a variety of high-precision landforms through different precise deformations, meeting the simulation needs of different scenarios. At the same time, the terrain change can be adjusted in real time and dynamically, improving the flexibility of landform simulation and strengthening the function of real-time dynamic regulation, providing a dynamically changing test platform.

[0037] The guiding unit 3 includes a plurality of first linear guide rails 31 independently arranged horizontally. The plurality of first linear guide rails 31 and the plurality of sliders 41 are all arranged to form the same even-sided polygon. In this embodiment, the polygon is a hexagon, that is, the shapes formed by the arrangement of the plurality of first linear guide rails 31 and the shapes formed by the arrangement of the plurality of sliders 41 are both hexagons. It can be understood that it is not limited to a hexagon, and it can also be a quadrilateral, an octagon, etc., and the arrangement shape can be flexibly adjusted according to the site conditions and the required simulation accuracy.

[0038] In another embodiment, the guiding unit 3 may also include two second linear guide rails symmetrically arranged horizontally relative to each other. At this time, the plurality of sliders 41 on each second linear guide rail are all arranged in a straight line.

[0039] In another embodiment, the guiding unit 3 is an annular guide rail, and the plurality of sliders 41 are arranged to form an annular shape.

[0040] In order to better provide positioning support for the plurality of first linear guide rails 31, preferably, the support frame 2 includes a plurality of support components. Each support component includes two support columns 21 arranged oppositely, and both ends of the first linear guide rail 31 are respectively fixed between the two support columns 21.

[0041] Preferably, the elastic member is an elastic thick steel wire 511, and the second elastic simulation member 52 is an elastic fine steel wire mesh 521, which has good strength, is convenient for repeated tensioning, and has strong deformation ability. The diameter of the elastic thick steel wire 511 is greater than the diameter of the elastic fine steel wire that makes up the elastic fine steel wire mesh 521.

[0042] Please refer to Figure 1 、 Figure 4 Preferably, the support platform 1 is provided with an electromagnetic induction power supply coil 11, and the slider 41 is provided with an electromagnetic induction power receiving coil 411, a signal receiver 412, and a micro motor 413. The electromagnetic induction power supply coil 11 and the electromagnetic induction power receiving coil 411 cooperate with each other to supply power to the micro motor 413 in the slider 41 without contact through electromagnetic induction. The electromagnetic induction power receiving coil 411 transmits the power to the micro motor 413, and the micro motor 411 converts electrical energy into mechanical energy. The signal receiver 412 is used to receive the signal instructions issued by the execution layer controller to control the operation of the micro motor 411. When the guiding unit 3 adopts the first linear guide rail 31 or the second linear guide rail, at this time, the micro motor 413 is a linear motor, and the slider 41 is driven by the linear motor to move horizontally along the first linear guide rail 31 or the second linear guide rail; when the guiding unit 3 adopts an annular guide rail, an arc-shaped rack can be installed on the annular guide rail. The micro motor 413 is a micro stepping motor, and the output end of the micro stepping motor is connected with a gear to cooperate with the arc-shaped rack to realize the movement of the slider 41 along the annular guide rail.

[0043] To facilitate the movement of the vertical driver 61 in the vertical direction to drive the first elastic simulation member 51, preferably, the power source of the vertical driver 61 includes a servo electric cylinder or a hydraulic cylinder. It can be understood that it is not limited to the servo electric cylinder or the hydraulic cylinder, and other driving members capable of realizing linear motion can be used, which are not defined herein. Specifically, the fixed end 611 of the vertical driver 61 can be fixed on the support platform 1, and the moving end 612 of the vertical driver 61 is aligned with the elastic thick steel wire and moves vertically, so that the elastic thick steel wire deforms, and then the elastic fine wire mesh deforms.

[0044] Preferably, a plurality of vertical drivers 61 are all located directly below the skin 53, further realizing high-precision and rapid response of the skin 53 shape change.

[0045] Before the simulation device of this embodiment is used, first, the elevation data file of the real landform is input into the landform simulation and simulation software to generate a general curved surface contour, and fitting is performed by inputting and fitting terrain feature points. The generated landform curved surface is parsed into spatial lattice points and slider target coordinate data, which are transmitted to the execution layer controller. Through the execution layer controller issuing instructions, the micro motor 413 of the corresponding slider 41 operates, driving the slider 41 to move horizontally in a straight line along the first linear guide rail 31. The slider 41 drives the elastic thick steel wire to move horizontally, so as to change the distribution density of the elastic thick steel wires 511 in different regions, and then change the support density of the elastic fine wire mesh 521 to adjust the detailed simulation of the plane terrain. The vertical driver 61 can move in a straight line in the vertical direction, driving the elastic thick steel wire 511 to elastically deform. The elastic thick steel wire 511 then drives the elastic fine wire mesh 521 and the skin 53 to deform, so as to adjust the macro elevation of the terrain. By controlling the elastic thick steel wire 511 to a specific position, the precise dynamic adjustment of parameters such as the elevation and slope of specific points on the landform curved surface is realized, and the required three-dimensional landform is accurately generated, such as Figure 5 the wavy landform shown, Figure 6 the random landform shown.
