BED TESTING METERS OF ANGULAR VELOCITIES Russian patent published in 1998 - IPC

FIELD: measurement technology. SUBSTANCE: bed testing meters of angular velocities has frame, platform of bed axis, DC motor, collector, source of calibrated voltage, two quartz pendulum accelerometers each incorporating quartz plate, capacitive angle transmitter and magnetoelectric transmitter of moment connected through proper feedback amplifiers which output stages are manufactured in the form of voltage dividers. Case of first accelerometer is so anchored on bed platform that its sensitivity axis is perpendicular to radius of platform and case of second accelerometer is so fixed that its sensitivity axis is arranged along radius of platform. Bed also has amplifier of stabilization system with adder, voltage integrator, photoelectric moire angle transmitter, phase interpolator and unit converting information of photoelectric angle transmitter connected in series, unit converting information of tested device, matching unit and computer. EFFECT: simplified design, improved functional efficiency and reliability of bed. 4 dwg
