ABSTRACT:
A damping body for damping periodically alternating loads uses a shape-memory alloy material to govern the damping. The damping body is sintered from metal grains or is laminated from a plurality of perforated sheet-metal layers. The individual sheet-metal layers are orientated transversely or parallel to the loading direction and are connected to one another over the full surface area. A combination formed from a multiplicity of round pins orientated parallel to the loading direction and having enclosed gussets can also be used as a damping body. A certain hollow-space portion inside the damping body can also be created by drilling, slitting or grooving. The proportion of the open pore or bore volume of the damping body to the total volume is at least 5%, preferably about 15 to 40%. On account of the hollow spaces integrated in the damping body, multiaxial stress states impairing the damping behavior can be effectively avoided or at any rate reduced even in an unfavorably flat or wide configuration of the damping body.
