Automotive Testing: Optical 3D Metrology improves Safety and Comfort

02/2015To speed up design, simulation and development cycles, the automotive industry relies on optical measuring systems. Applications include crash, impact and component tests as well as climate chamber, wind tunnel and fatigue testing.

Product development in the automotive sector is currently driven by strong competition, which causes shorter development cycles and high cost pressure. To speed up product development, the automotive industry increasingly uses optical measurement systems, instead of conventional strain gauges, accelerometers, transducers and extensometers.

Companies implement these non-contact sensors not only in crash, impact and component tests, but also in climate chamber, wind tunnel and fatigue testing. Particularly important for the industry is the fact that optical measuring systems can be fully integrated into existing test facilities and test stands.

Optical sensors provide data of part and component geometries as well as of three-dimensional displacements and deformations. Static and dynamic deformations are determined on the basis of individual points as well as entire surfaces. With this data, manufacturers can evaluate part safety and functioning, while also optimizing their simulation and design processes at the same time. As a result, product development can be noticeably accelerated.
