The Power of Engineering

Experts in bevestigingstechniek

Maandagochtend, de dag begint met een telefoontje van een klant uit het buitenland: “Tijdens montage van een kritische bout in een remsysteem zien we dat hij op het punt staat te breken. Op dit ogenblik rijden hogesnelheidstreinen met deze bouten in hetzelfde remsysteem. Die remmen kunnen het mogelijk elk moment begeven. Dit is een extreme noodsituatie!”

De technische experts van de afdeling Quality & Engineering bij Fabory schakelen direct: Nog dezelfde dag worden in het bijzijn van de klant de bouten beoordeeld op hun mechanische eigenschappen. Dat gebeurt in het geaccrediteerde laboratorium van Fabory. Gekeken wordt naar de treksterkte, de kernhardheid en de mate van ontkoling. Alle drie worden ze in orde bevonden volgens de eisen in de ISO 898-1.

 

Error in mounting method

The test results show that the bolts meet the requirements. But the mounting method used should not overload. How could the bolt be about to break? Follow a few telephone conversations with the assembly line. A detail appears to have changed in the mounting method. So that the bolts do not vibrate loose, two drops of a thread locker are applied. A second simulation on the friction test bench shows the consequences of this. The combination of coating and the relevant thread-locking agent lowers the friction coefficient. As a result, they loaded the bolts far beyond the yield strength during installation. The bolt load is still below the breaking strength. Unfortunately, they are being constricted and deformed. The connection is no longer safe.

Lower tightening torque is then written into the assembly instructions. They also recalled the trainsets.

 

 
 
"When using fasteners such as bolts and nuts, quality and technology go hand in hand. In the first place, fasteners must meet the quality requirements. But sometimes things go wrong in the application."
Tim Koopman, Manager Engineering
