Claim:
1. A testbench device for the analysis and/or optimization of the tribological properties in a piston ring/cylinder runway system, comprising: a cylinder segment-holding device configured to hold a cylinder runway segment as a testpiece; a piston ring-holding device having a piston with a ring-shaped outer contour and with at least one circumferentially continuous piston ring groove; a piston ring element held on the piston ring-holding device and capable of being brought into bearing contact with the cylinder runway segment, wherein the piston ring element is a piston ring arranged in the circumferentially continuous piston ring groove, wherein the piston ring-holding device includes a cylinder element at least partially surrounding the piston in a circumferential direction and having a cylinder running face in contact with the piston ring element; a reception block that prevents relative movement between the cylinder element and the piston; and an actuation device configured to actuate at least one of the cylinder runway segment and the piston ring element such that the cylinder runway segment is displaced relative to the piston ring element in at least one defined direction of space.
