Angular velocity sensor and angular velocity detector
The Journal of the Acoustical Society of America, 2008The present invention provides a cheap angular velocity sensor capable of detecting angular velocity with high precision by using a vibration mode which cannot be set by external vibration. The angular velocity sensor includes: a vibrator ( 2 ) formed as a solid of revolution and made of a magnetostrictive material; a supporter ( 3 ) disposed on an ...

An angular velocity detector using a vibrator made of an annular thin film. The detector also has electrodes arranged ingeniously to have high detection sensitivity for angular velocities. The detector can detect angular velocities in two axial directions simultaneously. The detector has support portions ( 1105 ), ( 1106 ) which are formed over a first

On the Relation between Angular Momentum and Angular Velocity
American Journal of Physics, 2007Students of mechanics usually have difficulties when they learn about the rotation of a rigid body. These difficulties are rooted in the relation between angular momentum and angular velocity, because these vectors are not parallel, and we need in general to utilize a rotating frame of reference or a time dependent inertia tensor.

Angular velocity measuring interferometer
Applied Optics, 1989A novel optical system to measure angular velocity based on the Doppler effect is presented. The system was developed to investigate the effect of rotation in the process of experimental modal analysis.

A mechanical analog of cyclotron motion is found and a scheme of the corresponding device, which can be called a stabilized rotator, is determined. The natural frequency of rotation of a stabilized rotator is strictly fixed (it does not depend on either the moment of inertia or the moment of impulse) and remarkably coincides with the natural frequency ...

Accelerometer Placement for Angular Velocity Determination
Journal of Dynamic Systems, Measurement, and Control, 1997An accelerometer placement scheme to determine the angular velocities and accelerations of a rigid body is presented. We show that the least number of uniaxial accelerometers required in a sensor array to uniquely determine the angular velocities in a moving frame is nine.

Angular velocity and time derivative of angular displacement
American Journal of Physics, 1986It is shown that, given the angular displacement vector Φ(t)for a rigid object, the angular velocity can be found by rotating dΦ/dt about Φ through angle 1/2 Φ and decreasing the component perpendicular to Φ by (1/ 1/2 Φ)sin 1/2 Φ. The result is illustrated by considering a regular precession at a fixed angle with the vertical.

Angular Velocity and Centripetal Acceleration Relationship
The Physics Teacher, 2014During the last few years, the growing boom of smartphones has given rise to a considerable number of applications exploiting the functionality of the sensors incorporated in these devices. A sector that has unexpectedly taken advantage of the power of these tools is physics teaching, as reflected in several recent papers.1–10 In effect, the use of ...

On the concept of angular velocity
European Journal of Physics, 1986Recent articles in this journal have proposed that certain rather specialised mathematical formalisms (quaternions, or alternatively dyads) should be employed in the derivation of the fundamental equations of rigid-body kinematics. Here, to the contrary, the merits are argued of a description based simply on the properties of rotation matrices.
