ABSTRACT:
A device for testing the contact-action effects between rotating and stationary structural elements of flow-related engines, such as turbine power plants, is formed of a motor driven rotary supporting arrangement for a rotational test element and a support frame for mounting a stationary test element so that the contact-action effects between the rotational test element and the stationary test element can be evaluated. The support frame for mounting the stationary test element includes positioning devices for adjusting the position of the stationary test element which is mounted on the support frame by way of a mounting block that is suspended by spring rods which are fastened to a yoke-forming portion of the support frame. Furthermore, according to the preferred embodiment, the mounting block is connected to the yoke in a horizontal plane which passes through the axis of rotation of the rotary supporting frame by connecting members, each of which include an elongation measuring strip instrument for radial or axial force measurement, respectively, and which are connected to the mounting block by means of a ball joint.
