The design results of the EMU cab will have an important impact on the overall EMU. Therefore, designing and manufacturing an EMU cab with smooth curved surface, beautiful appearance and compliance with aerodynamic requirements has become a focus issue for designers.

The requirements for scanning the high-speed train cockpit are very high, with large arcs and many curved surfaces. It is difficult to use traditional measurement methods to quickly and accurately obtain the three-dimensional model data of the high-speed train cockpit.

In response to the problems faced by customers, HOLON3D technical engineers proposed a solution to use: the handheld 3D scanner HL-3DH-3M to obtain the 3D data of the EMU cockpit. The EMU researchers used the scanned 3D data to calculate the subsequent train flow field numerically. , model wind tunnel testing, secondary design and product improvement of outer panel molds.

Scanning device:

Handheld 3D scanner HL-3DH-3M

Features:

1. Compact appearance, light weight (950g), easy to carry and use

2. No external AC power required, ready to use out of the box, no calibration required

3. Using corner point measurement, scanning speed is faster

4. The use of original corner-type marking stickers has higher positioning accuracy than the dot marking stickers commonly used in the industry.

5. Especially good at scanning complex-shaped objects (such as cars and interior parts, etc.), with high efficiency, good effect, and no blind spots.
