ARAMIS SRX – Sensor for High-End Applications

ARAMIS SRX

The new ARAMIS SRX is a 3D measurement system for dynamic evaluation of 3D coordinates, 3D displacement and surface strain. It comprises the latest camera technology including 12-megapixel cameras. Capturing up to 2000 images per second, the sensor is especially designed for rapid testing applications. It comes with an additional setup for crash applications providing an image acquisition rate of 1000 images per second in HD format. With the combination of high resolution and high speed, the ARAMIS SRX sensor is perfectly suited to high-end applications. The sensor is designed for high stability, process reliability and user-friendliness, which is why it is primarily used in industrial environments and applications.

ARAMIS SRX in Use

ARAMIS Technology

Sensor

The ARAMIS SRX sensor comprises the latest camera technology including two 12-megapixel cameras. The high spatial resolution allows detecting local strain effects with using large measuring volumes as well as measuring low strain levels. For large objects with narrow structures and small objects showing a high displacement, users can benefit from the high resolution by using small point markers.

In full resolution, the image recording rate of ARAMIS SRX is 335 Hz at the maximum, but it can be increased to 2000 Hz by reducing the image height. This allows, for example, capturing the failure behavior of parts in detail over time.

The internal 8-GB memory allows for a combination of high resolution and high speed. The ARAMIS SRX is particularly designed for high-end applications, which require both capturing high speed image sequences and measuring local effects.

The HD mode, which was especially developed for applications in the area of crash testing, offers an optimal image ratio in HD format with an image recording rate of 1000 Hz. It allows comprehensive analyses of high-speed sequences in high resolution.

Sensor Setup

The ARAMIS sensor is a stereo camera system providing precise 3D coordinates based on triangulation. The robust housing ensures high stability with a reduced need for sensor calibration so that ARAMIS SRX is ideally suitable for applications in industrial environments. The exchangeable camera frames and preset and certified measuring lenses allow for a fast adjustment of measuring areas. Furthermore, controlling the sensor using the GOM Testing Controller ensures stable communication between software and hardware. Due to the new technology, the image acquisition is controlled via trigger assignment within the cameras, ensuring the process stability of the sensor.

Light Projector

The light projector is used for measurement areas up to 1 m x 1 m and can be set to different illumination areas. With its Blue Light Technology it provides a stable light source for accurate measurements in all environments.

Tracking Spots

The Tracking Spots are used for the illumination of large areas up to 5 m x 5 m and optimized for pointwise measurements for motion analyses. The dual light source configuration utilizes the retro-reflecting effect of the used point markers and thus enables exposure times in the microsecond range for objects moving with high speed.

Calibration

The ARAMIS sensor calibration is carried out in the ARAMIS Professional software using certified high-precision calibration objects. The complete calibration procedure is user-guided ensuring always a highly accurate calibration result independent from the system operator. The standard ARAMIS sensor calibration is performed within only a few minutes.

Integration into Testing Environment

The integrated GOM Testing Controller not only controls the stage acquisition but also the light management. Furthermore, a software-based programming interface is integrated for preset or user-defined measuring sequences. The GOM Testing Controller fully supports the integration into existing test environments by means of external triggering and analog data acquisition.

Live Tracking
The Live functions of ARAMIS permit online measurement, positioning and motion analyses and they are supported by measurements with touch probes and adapters.

Long-Term Online Measurement

Online component testing is used, for example, in durability tests, fatigue tests as well as in wind tunnel tests and vibration analysis. At the same time, the measuring results can be viewed online or transferred to other programs using digital and analog interfaces and can be processed live by these programs.

In the online measurement, parts and their movements are specifically aligned and positioned to CAD. A typical application, for example, involves transforming the coordinate system of the simulation to the real measuring setup.

GOM Touch Probe

Touch probe – The GOM Touch Probe is a tactile measuring system extension that is optically tracked by the ARAMIS system. It is used for tactile measurements and makes it possible to measure coordinates on areas that are difficult to access optically.

GOM Adapter

GOM Adapters offer extended opportunities for live measurement, such as component alignments or measurements of regular geometries and edges.

ARAMIS Professional Live

Multi-Sensor

Combining several ARAMIS sensors, allows for measuring from various perspectives with different measuring areas. Here, the deformation behavior of a part is recorded simultaneously from all sides and evaluated in a common coordinate system.

Large Measuring Volume

For dynamic measuring of complex or large applications with dimensions of up to ten meters in size, ARAMIS enables evaluating the vibration behavior of individual blades of wind power plants under heavy loads caused by weather-related influences.

Verification of Numerical Simulation

ARAMIS sensors provide information on material properties of parts. This data is used as input parameters for simulation computations and reference size for optimization and verification. The GOM software allows importing FE data from formats including ABAQUS, LS-DYNA, ANSYS as well as aligning them to the measuring data and in space.

Kiosk – Automated Inspection

The ARAMIS Kiosk Interface is an user interface for automated evaluation of tensile tests complying with different standards. With minimized user interaction, standardized testing procedures can be carried out fast, easily and repeatable for measurement series with numerous specimens.

ARAMIS Professional Software
The ARAMIS Professional software offers the complete workflow from measuring data acquisition, via analysis, up to reporting.

The ARAMIS Professional software combines the functionalities of the ARAMIS sensors and the GOM Correlate software, thus offering a synchronized acquisition of images and analog data as well as evaluation functionalities.

GOM Correlate Software

GOM Correlate is a software package for digital image correlation (DIC) and 3D motion analysis in materials and components testing. The software is used for the determination of material properties as well as for the validation and optimization of numerical simulations. GOM Correlate is applied in basic research, product development and failure analyses.
