Zwick’s RKP 450 for Brugger tests on case-hardened steels
The instrumented pendulum impact
tester RKP 450 from Zwick has been designed for a maximum impact energy
of 450 Joules.
It is optimally suited for performing the Brugger test to determine the toughness and hardenability of case-hardened steel.
The dynamic force at break is the characteristic parameter for impact toughness. It is the maximum force of the recorded force-time characteristic for an impact test.
With the RKP 450 the specimen is gripped in a special two-screw clamping shell which allows reactionless clamping.
A special base-plate for exchangeable grips as well as the pendulum’s interchangeable impact fins makes it possible to use the impact pendulum tester for the Brugger Test as well as for the usual impact bending tests to Charpy.
The impact fin with its applied strain measurement strips (SMS) is highly stressed during this test. For that reason it is manufactured from high-strength steel. A special heat treatment makes it particularly resistant to wear. It is easily removed for reworking or exchange.
The force-time characteristic during the test is acquired, processed, and evaluated with a high measurement frequency
and a resolution of more than 65,000 measurement points. The underlying hardware and software package applied for this is testXpert® also from Zwick.
