Dynamic error research and application of an angular measuring system belonging to a high precision excursion test turntable

摘要

Angular measuring system is the most important component of a servo turntable in inertial test apparatus. Its function and precision determine the turntable' s function and precision. It attaches importance to research on inertial test equipment. This paper introduces the principle of the angular measuring system using amplitude discrimination mode. The dynamic errors are analyzed from the aspects of inductosyn, amplitude and function error of double-phase voltage and waveform distortion. Through detailed calculation, theory is provided for practical application; system errors are allocated and the angular measuring system meets the accuracy requirement. As a result, the schedule of the angular measuring system can be used in practice.
