Development and investigation of laser goniometric check system for measurement facilities of angular movement parameters

The work covers the stand equipment for dynamic test and investigation of the precise transducers "angle - code", gyroscopic transducers of angular velocities and accelerations and gravity-inertial devices. The aim is to develop the construction principles, to create and investigate the computer-aided laser goniometric system for checking precise facilities of measuring angular movement parameters and gravity gradiometer. The optimum structure of computer-aided stand has been proposed, the structure of the precise rotation speed stabilization system on base of the contactless electric drive with digital correction on the side of master action has been proposed. The laser goniometric measurement method has been improved. Thenew procedure for determining position of the measuring axle in the ring laser has been proposed. The experimental prototype of computer-aided stand having the increased accuracy, quick-action and widened functional possibilities has been developed. The large amount of the different measurement facilities has been performed on the new qualitative level. The developed programmed synthesizer can be used as an independent device for generation of the signals in the information-measuring systems and for control of the electric drives. The investigation results have been introduced in the plant made during performing the planned research works. They have been used also in two R and D works at making marine gravimeter and ship deformation meter. The increase of the discrete angular converter check accuracy and angular velocity reproduction more than one order has been achieved.
