WebA gimbal is a pivoted support that permits rotation of an object about an axis. A set of three gimbals, one mounted on the other with orthogonal pivot axes, may be used to allow an … WebSep 16, 2013 · The flywheel is modelled as a rigid rotor because its spinning speed is far below the critical point. The internal bearing systems provide compliant supports for the flywheel and the gimbal, which forms two sets of vibrating systems in the SGCMG: namely the flywheel- and gimbal-bearing system, as is shown in Fig. 1 (d). For the flywheel …

Gimbal lock is the loss of one degree of freedom in a three-dimensional, three-gimbal mechanism that occurs when the axes of two of the three gimbals are driven into a parallel configuration, "locking" the system into rotation in a degenerate two-dimensional space. The term gimbal-lock can … See more A gimbal is a ring that is suspended so it can rotate about an axis. Gimbals are typically nested one within another to accommodate rotation about multiple axes. They appear in See more The problem of gimbal lock appears when one uses Euler angles in applied mathematics; developers of 3D computer programs, such as 3D modeling, embedded navigation systems, and video games must take care to avoid it.
