Scantech’s reseller helped LR Motor Company in France to scan the tubular chassis of a race vehicle using the 3D scanner KSCAN 20. The CAD model generated from the scanned data served as a basis for the development of a new product, which helped the company to conceive a new high-performance buggy for competition.

Case Background
The chassis of race cars are different from those of ordinary cars, as the former focuses more on firmness, stability, and lightweight design. Those chassis are rigidly fabricated to meet the performance requirement of competitions.

Tubular chassis are mainly used in race cars due to the unrivaled sturdiness and the safety they provide. With a sturdy three-dimensional structure, they perform well in anti-vibration and stability.

LR Motor Company is well-known for its high-performance buggies. Their tubular chassis has a strong bearing capacity and torsional rigidity, which are resistant to impact, distortion, and inertial force.

The project is to create a new CAD model for use in manufacturing, thus updating the original chassis. Generating a CAD model of the original product by the 3D scanner can empower the company to analyze its physical structure after wear and tear and explore how it can be improved to create variations.

Challenges of the project
The race cars of LR Motor Company are designed and fabricated by hand in their workshops, which highly depends on the personal experience and craftsmanship of experts. To shorten the manufacturing cycle time, the manufacturer must find a more efficient way to capture precise dimensional data of cars to serve as the reference for further design. To remodel one or a group of handmade components on CAD can be challenging.

An efficient solution for inspection and maintenance is also needed for in-service race cars. The parts of race cars are subject to wear and tear during competition. It is necessary to identify potential wear parts in time to conduct thorough maintenance. The traditional procedure is complex, and the tools are complicated, which fails to accomplish the urgent tasks.

Scantech’s 3D solutions
This is where our 3D scanning technology can help. Using the 3D scanner, you can obtain a very high-precision digital twin of elements. It will be used as a “3D layer” to remodel objects.

In this project, LR Motor Company hired our reseller to capture the 3D data of the original tubular chassis for further design.

The 3D scanning was carried out with Scantech’s portable 3D scanner KSCAN 20 in LR Motor’s workshop. Technicians captured the accurate data of longitudinal side member, cross member, cross braces and, etc. The scanning results are shown as below:

The 3D scan data serves as a visual guide for creating the CAD model. In this project, armed with precise 3D data, engineers were able to get a CAD model of the chassis to prepare the manufacturing of a new product that has high performances.

Besides, 3D scanners can also be used by race teams to conduct a precise and in-time inspection of the wearing of parts. It can help them to intuitively identify the wearing parts and maintain the vehicle. The 3D scanner is simple to operate, and it can deliver intuitive data. Therefore, it can reduce the use of various inspection tools and greatly simplify the detection and maintenance process.
