Automated system for calibrating instruments measuring parameters of moving objects

The present paper views a model of a system for checking and calibrating measuring instruments operating on moving objects, in particular on ships. The system is a stand simulator based on a six-degree-of-freedom Stewart platform, which actually provides the required sensitivity, manoeuvrability and accuracy of motion of the operating platform. An effective control algorithm, presented in details in this paper, has been created on the basis of the developed mathematical model of the kinematics of the mechanical module. The mathematical model, based on the inverse kinematics problem of parallel mechanisms, is universal enough to be used in the development of other systems for calibrating devices operating on various moving objects such as automobiles, aircrafts, etc. The referential qualities of the system are ensured by a specifically developed output device which is calibrated by means of references for length. The qualities of the system are confirmed by the results obtained from the experiments done.
