Abstract
A testbench device for the analysis and/or optimization of tribological properties in a piston ring/cylinder runway system, includes a cylinder segment-holding device for holding a cylinder runway segment as a testpiece, and a piston ring-holding device holding at least one piston ring element and capable of bringing the at least one piston ring element into bearing contact with the cylinder runway segment. An actuation device actuates the cylinder runway segment and/or the piston ring element such that relative displacement with respect to one another takes place in at least one defined direction of space, in particular in the form of an oscillating movement. The piston ring-holding device has a piston having a ring-shaped outer contour and with at least one circumferentially continuous piston ring groove, in which a piston ring is held as a piston ring element.
