摘要： A single vibration sensor having the capability of sensing vibration along three rotational axes as well as three translational axes and exhibiting consistent dynamics over a wide frequency range. The sensor includes an elongated mass formed of a generally rigid material suspended in a fluid within a housing. The exterior surface of the mass is spaced from the interior surface of the housing to permit limited freedom of motion of the mass within the housing. The mass is provided with multiaxial radial and axial electromagnetic suspensions, and is typically supported by a fluid within the housing. Rotational positioning is provided by a signal generator, torque generator combination. Vibration is sensed by additive or differential measurements of current changes in the coils of different axes of the suspensions or electromagnetic signal and torque generator combinations. The sensor is conveniently implemented as a single degree of freedom inertial gyroscope without the gyroscope wheel and adapted to permit sensing of current changes in coils provided to achieve suspension or suspension and signal and torque generation functions.
