The properties of mechanical components can be determined with nondestructive testing. This is the principle of MAUL-THEETs Quality-Testing-Software. Based on vibration tests throughout the manufacturing process the labels ‘good’ or ‘bad’ can be given to a specific manufactured component.
Mechanical structures have typical dynamic properties. These vibration properties can be described with the eigenfrequencies, the modal damping and the eigenforms. Identical structures have also identical dynamic properties. After the acquisition and comparison of these dynamic properties it is possible, to detect errors and deviations of the components. The determination of the properties is done with a FTT-analysis-system, which is integrated together with the evaluation and control software in one PC.
The dynamic properties enter the MAUL-THEET Quality-Testing-Software as quality criteria. Other criteria can be e.g. the weight or the electrical resistance.
All criteria are connected to one quality key number in the set-up module. The weighting and the optimal connection of the single criteria can be set in this module. The set-up module ‘learns’ after testing a few components of good and poor quality to distinguish good and bad quality components. Its learning ability remains also during its operation in the production process.
The MAUL-THEET Quality-Testing-Software enables the customer to detect components of poor quality during the operating production process and to remove them from the production chain. The early detection of broken parts reduces the possible consequential costs or prevent the standstill of the production. Defect parts, which are welded into a bigger structure for example, can lead to a really expansive post-processing or to the complete loss of the whole assembly. For example an imploded glass bulb leads to the standstill of a whole production street since the splinters needs to be removed.
The test system can be used to test the following parts among others to detect e.g. geometrical deviations, material errors or faulty bonds.
Turbine blades
Glass bulbs
Forged parts
Aluminium parts
Ceramics
Picture tubes
Sheet metal parts
We deliver complete, to the specific technical needs of our customer adjusted test systems. To be able to offer our customer an optimal solution we proceed along the following three steps:
Consulting, feasibility analysis, cost evaluation
Preliminary examinations, Determination of the quality criteria
Installation of the test system, commissioning and training
The customer can also perform one or more steps if it suits him. For preliminary examinations we offer systems to rent and trainings also for longer periods of time. The installation as well as the maintenance can be done by the customer himself.
