Embodiment Construction
[0015] figure 1 It is a schematic flow chart of the method for matching virtual prototypes of rail vehicles provided by the embodiment of the present invention. Such as figure 1 As shown, the rail vehicle virtual prototype car matching method provided in this embodiment includes:
[0016] Step 100, calling part of the model, material and / or color of the virtual prototype vehicle according to actual needs.
[0017] Specifically, some models in the virtual prototype can be called in real time according to the actual needs of the user, for example, different types of front models, or different types of materials, or different colors can be called.
[0018] Step 200, replace part of the model, material and / or color of the virtual prototype vehicle according to actual needs, and create a new virtual prototype vehicle.
[0019] Specifically, some models of existing virtual prototypes can be replaced according to user design, verification and other requirements, for example, model...

The present invention provides a method and a system for matching a virtual vehicle sample of a railway vehicle. The method comprises: calling part of models, materials and / or colors of a virtual vehicle sample according to an actual demand; and replacing the part of models, materials and / or colors of the virtual vehicle sample according to the actual demand, and building a new virtual vehicle sample. By using the method and the system for matching a virtual vehicle sample of a railway vehicle provided in the present invention, part of models of the virtual vehicle sample can be replaced in real time, and materials and colors of the sample can also be replaced in real time, and components of an existing virtual vehicle sample can be repeatedly used, thereby reducing production and modification periods of a virtual vehicle sample.
Description
technical field [0001] The invention relates to virtual reality technology, in particular to a method and system for selecting and matching virtual prototypes of rail vehicles. Background technique [0002] Virtual reality technology has been successfully applied in many complex equipment manufacturing industries. Virtual reality digital prototype technology has become a key technology to improve design and development capabilities, and is applied to multiple links such as design, assembly and manufacturing. [0003] In the design and production process of high-speed trains, virtual prototypes have been used to replace real physical prototypes, which can be used to visualize the shape, structure, layout and interior of high-speed trains, as well as intuitive design review and functional verification. On the other hand, it can also allow customers to participate in the design, so that users can more intuitively understand the product design results and technical level before ...
