The development and design of test rigs for research work must take account from the start of the measuring equipment since it is the latter which mainly determines the subsequent use of the rig. This article describes the procedures when making changes to improve the dynamic behaviour of the mechanical components and the measuring equipment on a rotary test rig. A specification for the conversion of the rig was developed from a so-called weak-point analysis, and the new concept of the rig intermediate station derived from this is explained with the aid of a diagram which shows all the main features. Since the new concept is such that apart from the rotational motion all movements and the contact force of the rolls are controlled servo-hydraulically, new performance data for the test rig are obtained. The rig is also more convenient to operate. The conversion work on rotary test rig II and the necessary tests have been concluded, and the various tests for the experimental investigation of the adhesion force laws have been commenced. Suitable running-in conditions and roll forms are being developed in preliminary tests, by means of which a surface, texture and inherent tension condition in the running surfaces is obtained which approaches that of the wheel and rail. In the main test series the effect of slip, material pairing and ambient conditions on the adhesion coefficent and the coefficient of sliding friction will be examined.
