Structural Prototype

After the three-dimensional structural design of the product is completed, DMU structure prototype review is required for the design data.

Structural Virtual Prototyping Review Solution

After the three-dimensional structural design of the product is completed, DMU structure prototype review is required for the design data. The traditional CAD data review based on PC has a large amount of data, which cannot be reviewed by the whole vehicle, the screen size is small, the number of people participating in the review is limited, and the viewing angle is limited. Through virtual reality technology, 1: 1 immersive virtual prototype review can be realized, so that designers can truly feel the product size, intuitively find design interference, and improve communication efficiency as if they were in a real product. The use of virtual reality systems for structural prototype DMU review has become a mainstream choice for current users.

In response to market demand, and far launched the iVPD virtual prototype review system, the architecture of which is shown in the following figure:

The virtual prototype review system is mainly composed of the following three parts.

(1) The virtual prototype review software platform Techviz, based on graphic image processing technology, can directly visualize the applications used in the current work with ultra-high resolution, and supports a variety of VR display schemes (including head-mounted displays, single-channel stereo display systems, multi-channel stereo display systems, CAD wall, cave, etc.), easily creating 1: 1 scale display screens. Using lightweight and data optimization technology, the whole vehicle data can be displayed smoothly.

(2) The stereoscopic display system provides a stereoscopic virtual reality environment for users to immerse themselves in the virtual environment and interact with the virtual world. CADWall, cave, or virtual reality headsets are available in different sizes depending on customer application requirements.

(3) The art tracking interaction system is responsible for collecting the input information of users and providing basic data for natural interaction between people and the virtual environment. Can track the position of human eyes and hands, while using a wide range of tracking, allowing people to walk in virtual reality environment, to achieve natural interaction.

The structure virtual prototype review system can be applied in the following scenarios:

1. Check and monitor the vehicle design and point out relevant issues in order to ensure design quality and project progress.

2. Provide visualization functions of various types and grades, and conduct a comprehensive review of the structural prototype in different ways to evaluate and simulate realistic visual effects. See the same effect of products in the real world in a virtual reality system, enabling low-cost, high-efficiency product visualization simulations.

3. Functional analysis of vehicle models or components, including: mechanism movement, interference, disassembly, space and management analysis, etc. As much as possible, the same analysis as in the real world is carried out in the digital environment, so that designers can find problems at the early stage of design, and conduct various analyses in time and in large quantities at all stages of design, so as to improve the quality of product design.

4. Check configuration and part integrity

The application of the structure virtual prototype review system can visually carry out multi-department collaborative review and decision-making, improve the quality of design data, reduce late-stage engineering changes, and improve the competitiveness of enterprises.
