Lifetime Testing with a Zwick Vibrophore |
|
The DaimlerChrysler Research Institute in Ulm, Germany, took a new Zwick Amsler 20 HFP 5100 vibrophore into operation at the end of 2004. The dynamic testing machine is used in the Metals Department of the Production and Materials Technology Business Unit to determine the lifetime of fasteners using different specimen geometries.
These fasteners are made by either spot welding, laser beam welding, clinching, riveting, and bonding are particularly common in vehicle bodyshell construction. The vibrophore brings its specific strengths to bear in this case as it principle of operation is resonance.
The electromagnetically driven machine has a force capacity of 20kN and can generate testing frequencies from 35 to 300 Hz. To meet DaimlerChrysler’s demanding requirements, the testing machine was equipped with a vibration displacement measurement system on the vibration crosshead.
This allows the vibration displacement of the specimen to be determined very accurately. Zwick's intelligent testXpert® software is used for this application as it guarantees high precision and simple and intuitive operation.
The modular construction allows application-specific solutions such as "Single-Step Dynamic Fatigue Test” whilst an integrated wizard supports the operator and ensures that nothing is overlooked. As a result the personnel at the Research Center in Ulm found that they were able to perform tests to their full satisfaction only after a short training period.
