Engine and transmission durability and prototype testing development is a necessity in today's competitive Automotive marketplace, which is demanding longer warranties on powertrain components. In the last several years these tests would typically run the test objects until they were nearly destroyed. Today, with the use of the delta-ANALYSER this is no longer the case, as it will turn off the test stand at a predefined damage level. This will guarantee that the test specimen is not totally destroyed and the development engineer can obtain valuable information as to what has caused the root problem. The delta-ANALYSER will then provide this detailed information as to the failure path and cause of damage which in turn will offer a substantial time and money savings.
Time and labor are the top cost factors in all companies. This is especially true for end of line quality testing of gears and engines. Current testing systems must set up inspection standards and be constantly monitored and adjusted. This is no longer the case with the Reilhofer KG eol-ANALYSER. Once the system is installed on your test bench there is no need for an NVH specialist to monitor it or make periodic adjustments. The system is designed to independently find and make the necessary adjustments automatically to make the distinction between good and noisy transmissions or engines. The eol-ANALYSER automatically recognizes the production variables and adapts the acceptance criteria to the entire production process. This enables the system to assure the acceptance/reject tolerances stay consistent throughout the production process eliminating costly retests and false rejects. The number of different transmissions and engines models the system can handle is not a concern.
Q-800 Portable Laser Shearography System by Dantec Dynamics
Shearography is a widely recognized optical measurement technology providing fast and accurate information about defects inside a wide range of composite materials.
The Q-800 Laser Shearography System is a compact and fully portable NDT measuring solution that can detect defects including delaminations, disbonds, kissing bonds, wrinkling, impact damage and many more with no surface preparation. The turnkey optical system is non-contact and full-field and will work on such materials as fiber-reinforced plastics, laminates, honeycomb, foam, wood, metal and GLARE.
The results are displayed live to the operator allowing an early judgment to be made. Further image processing is also available for export and reporting. Typical inspection times are 10 to 30 seconds and can cover areas from a few mm2 up to several m2 in one inspection. The Q-800 system consists of a miniaturized shearography sensor with integrated high-resolution CCD and variable computer controlled shear optics. Illumination is provided by an integrated diode laser array and the whole system is controlled from a laptop PC using the new ISTRA 4D software platform. The sensor can be mounted on a tripod or integrated into a fully automatic robotic production inspection system.
The system can be operated in daylight conditions using the standard laser diode array. For illumination of large measuring areas an external laser can be coupled to the sensor head with a flexible glass fiber.
Q-810 Laser Shearography Inspection System for Field use
The portable Q-810 Laser Shearography Systems are fully integrated NDT systems using laser shearography suitable for defect detection in composite materials over large surface areas.
State of the art NDT Performance
The Q-810 Systems can detect defects including delaminations, disbonds, kissing bonds, wrinkling, impact damage, crushed core and many more with no surface preparation. They can also be used to investigate structural integrity, separation of structural components and bond lines. The turnkey optical systems are non-contact and full-field and will work on such materials as carbon-fiber, glass-fiber, laminates, honeycomb, foam, metal and GLARE.
Large Surface Area Coverage
The integrated systems are optimized for large surface area inspections, for example on aircraft fuselages, wings, control surfaces, ship hulls, wind turbine blades and rocket components. The full-field inspection rate is a rapid
300mm x 200mm every 10 seconds. With adaptive seals the systems can be used on flat as well as highly curved surfaces. The systems operate independently of the local environmental conditions and can be used for production or in-field inspections.
Varian Industrial Computed Tomography Systems
Computed Tomography (CT) creates cross section images by projecting a thin-beam x-ray through one plane of an object from many different angles. As the
x-rays pass through the object‚ some radiation is absorbed‚ some is scattered‚ and some is transmitted. In some scanners a cone-beam covers an area detector so that many slices‚ or a volume‚ can be scanned at once.
The radiation transmitted through the object at each angle is measured and referred to as attenuation data. It is a measure of the reduction in x-ray intensity that results from absorption and scattering by the object.
In CT scanning‚ the attenuation data is summed over the many different angles from which it was collected using a computer in a method called‚ reconstruction. Reconstruction essentially "builds" the CT image from the data collected and represents a cross section of the object
CT scanners typically consist of four hardware subsystems: a radiation source‚ a radiation detector system‚ a mechanical manipulator‚ and a computer with display. The radiation detector system is composed of detection elements‚ such as scintillating crystals and photodiodes. A data acquisition system (DAS) measures radiation data transmitted through the object and digitizes it into a format that can be handled by the scanner's computer system.
A mechanical manipulator is needed to precisely move the object relative to the x-ray source and detector system. Finally‚ a CT system requires a computer to control the scan motion and the timing of data acquisition. The computer then reconstructs the image from raw scan data.
Cross-sectional CT images are much easier to interpret than conventional radiographic images because features in the image do not overlap. Accurate positioning of internal features can also be identified. In addition‚ density differences within the object are easily identified as well as quantified‚ and can be related to desirable or undesirable features of the object or material. Finally‚ scan parameters such as cross-sectional slice thickness or data collection time can be varied to achieve the best combination of image quality and inspection time.
As computed tomography technology developed‚ researchers created improved methods of collecting the x-ray projections through an object. These methods were called generations‚ and use different motions to collect the projections.
