The paper introduces the results of studying the characteristics of various dynamically tuned gyroscopes operating in the mode of a variable rate sensor. Within the study, we determined the dependence of the dynamic error of the rate sensor on the amplitude and frequency of angular oscillations of the gyroscope body. We analyzed the methodological and hardware support for evaluating the dynamic error of a dynamically tuned gyroscope — the rate sensor in order to reduce its influence on the operational characteristics of the device. To experimentally research and practically evaluate the dynamic error of the dynamically tuned gyroscope — the rate sensor, we proposed a design of the rotary vibration test bench, developed requirements for it, and calculated its elastic-mass characteristics.

The work presented here explored the detrimental consequences that resulted when mechanical impedance effects were not considered in relating vibration test requirements with field measurements. The ways in which these effects can be considered were evaluated, and comparison of three impedance methods was accomplished based on a cumulative damage criterion. A test structure was used to simulate an equipment and support foundation system. Detailed finite element analysis was performed to aid in computation of cumulative damage totals. The results indicate that mechanical impedance methods can be effectively used to reproduce the field vibration environment in a laboratory test. The establishment of validated computer models, coupled with laboratory impedance measurements, can eliminate the overtesting problems inherent with constant motion, infinite impedance testing strategies.
