Automotive exhaust catalytic converter scanning

Manufacturers of automotive exhaust gas treatment components need to purchase a 3D scanner to assist in the design of the vehicle's three-way catalytic converter and accelerate the development of new products.

Practical problems

1. Since the three-way catalytic converter involves the connection with multiple components, the accuracy required by the customer is very high.

2. The three-way catalytic converter of the automobile has the characteristics of complex shape, large change of the overall line amplitude, and many connected nodes, and adopts the traditional manual measurement method, which is very time consuming and the data is not accurate enough.

Hualang solutions

In view of the complex shape, large curvature change and many connected nodes of the automobile three-way catalytic converter, Hualang 3D technical engineer proposed a solution to quickly obtain high-precision 3D data of the vehicle three-way catalytic converter using the 3D scanner HL-3DX+. The reverse design software Geomagic Studio (converts the three-way catalytic converter point cloud data into triangular mesh surface data) + Pro/E, UG and other mainstream design software for post processing. HL-3DX+ adopts extrapolation multi-frequency phase shift grating technology, code point calibration technology and fully automatic splicing technology. The scanning speed is fast and the precision is high. It takes only 15 minutes to obtain the three-dimensional data of the three-way catalytic converter of the automobile, and the data precision is as high as 0.02 mm. The acquired three-way catalytic converter data is imported into three-dimensional reverse software (Geomagic) for processing, and then imported into mainstream design software such as Pro/E and UG to carry out reverse design of automobile three-way catalytic converter, which accelerates the development of new products. .
