Vehicle engineering
Suspension development

In order to optimize vehicle ride comfort and handling it is important to understand actual wheel motion during driving maneuvers. This can be done by driving the car on the road or by putting it on a dynamic K&C rig.

In the case of road tests, the Metris WheelTracker provides detailed wheel motion information with a minimal impact on vehicle dynamics. On a dynamic K&C rig, the K-Series dynamic motion measurement (DMM) system tracks wheel motion in real-time.

Packaging studies

Understanding the actual movement of wheels and the powertrain while driving over rough road surfaces or executing extreme maneuvers is key in packaging studies. Metris WheelTracker and EngineTracker provide a contactless approach to wheel and powertrain displacement measurements in the field.
 
Experimental motion analysis

Measuring large displacements like the opening and closing of the glove compartment or a convertible roof is not obvious, but not for the K-series dynamic motion measurement system. The K-series system tracks the displacement of multiple targets in parallel up to 1,000Hz.

CFD, FE and crash simulation support

“Computational Fluid Dynamics” (CFD) simulations are used in combination with wind tunnel tests on scale models and full prototypes to optimize the aerodynamic properties of vehicles. In order to get reliable CFD calculations it is important that the description of the vehicle surfaces corresponds well to the actual vehicle model. The best way to get this is by scanning the model using the K-Scan  or ModelMaker handheld laser scanning solutions.
 
Also Finite Element (FE) calculations used for strength, dynamic and thermal simulations rely on the correct dimensional properties of the test specimen. This information is mainly retrieved from CAD data, but sometimes however CAD drawings are not available or don’t reflect the latest status of the physical model. The point clouds generated by the Metris line and cross-scanners mounted on a CMM can be converted into surface meshes which serve as input to create the appropriate FE meshes.
 
In order to validate the validity of crash simulations, it is important to compare calculated deformations of the vehicle body with the results of physical crash tests. These deformations can be captured using the K-Scan  and ModelMaker  handheld laser scanners.
