3D scanning of automotive anti-roll bars

The function of the car anti-roll bar is to reduce the roll of the vehicle when cornering and improve ride comfort. From small cars to heavy trucks, the front overhang is mostly equipped with stabilizer bars. Due to the need to avoid other surrounding parts when designing, stabilizer bars come in a variety of forms, but they are basically the shape of flexor arm and torsion bar. In addition, the cross-section of the material has two forms: solid and hollow, and the use of hollow materials that are beneficial to lightweight is increasing, and the demand and application volume of the automotive anti-roll bar market are also increasing correspondingly.

A well-known auto parts manufacturer at home and abroad, in order to measure the three-dimensional data of the anti-roll bar, the obtained three-dimensional data is compared with the original data for comparison, and a very intuitive three-dimensional detection chromatogram can be obtained. According to the comparison report, the overall deviation between the actual anti-roll bar and the original design drawings can be clearly seen, and the error of the workpiece can be clearly known.

面临问题| Practical problems

The symmetrical center of the anti-roll bar of the car is extended to the two pairs of sides to detect deviations. Detect wear and deformation of the joint between the anti-roll bar flexion arm and the car. The car anti-roll bar is rounded, and the surface cannot be pasted with too many points, which will affect the surface characteristics and cause detection deviations. Traditional detection methods are time-consuming and difficult to detect, and detection deviations will occur.
