Background Art

[0002] Topography refers to the undulating changes in terrain height. As a common manifestation content of civil engineering sites, topography can provide boundary conditions for the surrounding site environment of buildings and bridge structures, and one of its main manifestations is the impact on the environmental wind field of structures. Currently, in the field of wind resistance of buildings and bridges, the consideration of complex underlying surfaces on land is still insufficient, especially the impact of landform changes on the wind field and the wind-induced vibration response of structures. How to accurately simulate topography is one of the important research topics for those skilled in the art.

[0003] Landform simulation is a key technology for reproducing and studying complex terrain features, and is widely used in fields such as geological exploration, engineering design, and environmental simulation. Traditional expressions of topography are often single and static, that is, during the simulation of the entire scene, once the terrain model is processed, it cannot be changed. If certain specific parameters are changed, it is necessary to model and process again. Due to the changeable characteristics of landform, there are often disadvantages such as large engineering quantity, long time consumption, and material waste.

[0004] Traditional landform simulation devices usually rely on static or single terrain modeling methods, and it is difficult to meet the requirements of dynamic adjustment and high-precision reproduction of complex landform features. In practical applications, due to the diversity and randomness of terrain, existing devices have significant limitations in terms of flexibility, accuracy, and real-time performance.

[0029] Referring to

[0030] Please refer to Figures 1 to 7As shown in the figure, the present invention provides a specific embodiment, which provides a geomorphic simulation device. The geomorphic simulation device includes a management unit, an execution unit, and a simulation unit. The management unit is used to input different parameters to control the execution unit. The execution unit performs corresponding actions according to the instructions of the management unit. The simulation unit includes a skin 1 for simulating the geomorphology. The actions of the execution unit cause the skin 1 to present different geomorphic forms.

[0031] The present invention proposes an innovative dynamic and customizable geomorphic simulation device, which is convenient for the accurate static reproduction and dynamic adjustment of geomorphic models in different modes. This geomorphic simulation device can significantly improve the accuracy of geomorphic simulation and the response speed of evolution changes, adapt to the diverse needs of complex geomorphic simulation, and provide a new technical path for engineering applications and scientific research. This device has high precision and flexibility, can meet the needs of complex geomorphic simulation, and is applicable to fields such as geological exploration, engineering design, and environmental simulation. Thus, it solves the problems of static modeling, insufficient flexibility, and slow response speed of traditional geomorphic simulation devices.

[0032] Further, the execution unit includes a transmission shaft 4 and a servo motor for driving the transmission shaft 4. The simulation unit further includes a plurality of bendable connecting members 2 and support members 3. The transmission shaft 4 is connected to the skin 1 through the connecting member 2. The servo motor drives the transmission shaft 4 to adjust the form of the skin 1. The support member 3 is arranged between the transmission shaft 4 and the skin 1 for supporting the skin 1.

[0033] Specifically, the transmission shaft 4 and the servo motors are arranged in multiple groups, which are arranged at different positions of the same connecting member 2 or on different connecting members 2. Thus, according to the control instructions of the management unit, the corresponding transmission shaft 4 and servo motors perform corresponding actions, causing the skin 1 to present different geomorphic forms.

[0034] Specifically in this embodiment, both the connecting member 2 and the support member 3 are elastic steel wires, and the diameter of the connecting member 2 is greater than that of the support member 3. The deformation of the elastic steel wire drives the skin 1 to generate the required three-dimensional terrain, realizing the dynamic simulation of the geomorphology.

[0035] The plurality of connecting members 2 include a first group of connecting members and a second group of connecting members. The connecting members in the first group of connecting members are parallel to each other, the connecting members in the second group of connecting members are parallel to each other, and the first group of connecting members and the second group of connecting members are perpendicularly arranged. The support member 3 is alternately arranged with the connecting members of the second group of connecting members.

[0036] The power source of the execution unit is an electric control or hydraulic pressure actuator 6. The actuator 6 drives the transmission shaft 4, driving the connecting member 2 and the supporting member 3 to generate displacement deformation, thereby adjusting the shape of the skin 1. Therefore, this landform simulation device supports the real-time simulation of large-scale dynamic terrain and meets the diverse requirements of complex landforms. It provides an ideal experimental platform for studying the nonlinear landform evolution process and supports the multi-field coupled dynamic simulation of terrain and external environment. Among them, the external environment includes, for example, water flow, wind force or geological stress, etc. A support platform 5 is provided between the transmission shaft 4 and the actuator 6.

[0037] Furthermore, the management unit includes surface simulation software. The surface simulation software fits the spatial lattice control coordinates by inputting the spatial feature points of the landform and transmits the data to the execution unit. The surface simulation software generates a random landform surface through random numbers, generates a landform surface through a regular paraboloid, or fits a landform surface by inputting the spatial feature points of the terrain and landform. This landform simulation device realizes the automatic adjustment of landform parameters through the surface simulation software, reduces model processing, and improves the diversity and convenience of the simulated terrain.

[0038] The surface simulation software of the landform simulation device can instantaneously adjust the landform state according to the set control parameters, and the control parameters include wave frequency and wave height.

[0039] In addition, the material of the skin 1 can be replaced according to the requirements of the surface roughness. Designed in this way, materials can be saved to meet the needs of scientific research experiments and engineering applications.

[0040] The landform simulation device provided by this preferred embodiment sets a management unit, adopts surface simulation software, efficiently simulates and generates a landform model through digital means, and converts it into executable physical control instructions. On the one hand, the spatial feature point data of complex terrain is processed by a precise algorithm to generate an accurate surface model; on the other hand, the simulation unit relies on a high-precision array servo motor control system and a surface-tensionable elastic skin to convert the virtual model into a visual actual landform performance. Thus, the dynamic and customizable landform simulation technology effectively solves the problems of single fixation and cumbersome processing of traditional terrain simulation by re-designing the surface simulation software and improving the form of the controller.

[0041] The technical effect expected to be achieved by the present invention is that in the simulation of complex mountainous landforms, the surface simulation software of the management unit generates the coordinate data of the spatial feature points of the landform surface by inputting a specific mathematical surface and transmits it to the execution unit, controlling the array servo motor and the surface elastic skin 1 to complete the landform simulation, thereby realizing the morphological adjustment of various landform surfaces, such as wavy, canyon-shaped, parabolic, random-shaped and other landform types, specifically such as Figures 4 to 7, flexible and variable, only requiring the input of the required landform type on the computer. When the surface roughness needs to be changed, only the skin material needs to be replaced, saving a large amount of materials with fixed forms required for traditional model making; the invention can be applied in industrial mass production.

[0042] In this landform simulation device, the methods for generating the landform model surface on the surface simulation software of the management unit include: first, generating a random landform surface through random numbers; second, generating a landform surface through mathematical surfaces such as regular paraboloids; then, fitting the landform surface by inputting the spatial feature points of the terrain and landform. Finally, obtaining the spatial lattice control coordinate data from the generated landform surface, transmitting the lattice control data to the controller of the execution unit, and controlling the servo motor by the controller of the execution unit to complete the simulation of the actual skin on the landform surface.

[0043] This landform simulation device can generate complex three-dimensional landform shapes to meet diverse experimental needs; this landform simulation device supports precise control of terrain parameters and external forces, providing guarantee for experimental repeatability. The terrain parameters include, for example, slope, height distribution, geological composition, etc., and the external forces include water flow rate or wind speed, etc.

[0044] The above is only a specific implementation manner of the present invention, and any improvement made on the premise of the present invention's concept is regarded as the protection scope of the present invention.
