The process of designing a pendulum impact tester for consistently low natural vibrations begins in the vicinity of the specimen, with the pendulums and fixtures.
Zwick uses high-performance carbon materials for its HIT pendulums. These offer the following advantages:
- Significantly greater pendulum stiffness
- Ideal distribution of mass
- Repeatable, reproducible test results.
You can test in a measurement range up to 80% of potential energy. This is made possible by the very high ratio of instrument mass to pendulum mass.
Changing between the various HIT fixtures is quick, while precision guides guarantee a continuous positive-fit to the baseplate.
