Impact energy
The impact energy (also impact force ) is the kinetic energy that is released when one body hits another. It is given in joules .
Impact energy is z. B. used in mechanical engineering and there in tools . For an electric hammer drill or a hydraulic hammer , this means that the impact becomes harder with higher impact energy. For the operator, this means that he can drill a hole faster.
Another area of application of the term "impact energy" can be found in the area of forming and especially in forging (e.g. air hammer ). Here this means the force of the tool (e.g. a mechanical hammer) acting on the material to be processed.
The impact energy also plays a role with PC keyboards . The keyboards are divided into IK classes, for example. The IK level of impact resistance describes how much impact energy is required to press the button.
