ABSTRACT

Large rotary drum machines are often used in technological lines for continuous production. These are complex structures which during operation are exposed to stresses and deformations under the influence of temperature and stress. To determine the geometric parameters of such units in this paper we propose to use a total station. The basic idea of the method is remote real-time geodetic measurement of the machine parameters in the reflectorless mode. The task posed is solved by simultaneous measuring of the points spatial coordinates on the rotating machine and timing of the measurement. As a part of the work the mathematical model was constructed through which the geometrical parameters of the rotation body and various random and systematic influencing factors were investigated. For the implementation of the proposed technology the geodetic measuring complex "Vizir 3D» was updated accordingly. This paper shows an example of measurement of a drying unit and the evaluation of the parameters accuracy.
