Abstract

The invention relates to a test bench arrangement (1) comprising a test space (4) which is designed to receive a test object (7), and comprising at least one drivetrain test bench (3) which has at least one electric machine (8) and a shaft assembly (2) with a first end (21) and a second end (22), wherein the first end (21) is or can be connected in a rotationally fixed manner to the electric machine (8), and the second end (22) is designed to attach the test object (7) via a rotationally fixed connection (25), and wherein the shaft assembly (2) is supported in a rotational manner in a shaft carrier (10) via at least one intermediate bearing (11, 12). In order to achieve substantial airborne and structure-borne sound decoupling between the drivetrain test bench and test object, the invention proposes that the electric machine (8) and the first end (21) of the shaft assembly (2) are located outside the test space (4) and the second end (22) of the shaft assembly (2) is located inside the test space (4), wherein the shaft assembly (2) is guided through a wall lead-through (13) of a wall (6) of the test space (4), and the shaft carrier (10) forms a shaft bridge (20) which at least partially receives the shaft assembly (2), wherein the shaft bridge (20) is self-supporting in the test space (4).
