...Sung K. Koh; G. K. Ananthasuresh A sequence of rotations considered in this paper is a series of rotations of an untethered rigid body about its body-fixed axes such that the rotation about each axis is fully reversed at the end of the sequence. Due to the noncommutative property of finite rigid...

...Sung K. Koh; G. K. Ananthasuresh; Christopher Croke A fully reversed (FR) sequence of rotations is defined as a series of rotations of a free rigid body about its body-fixed axes such that the rotation about each axis is fully reversed at the end of the sequence. Due to the non-commutative property...

...Kenichi Makita; Masanori Kagotani, Professor; Hiroyuki Ueda, Lecturer; Tomio Koyama, Professor, Synchronous belt drives are widely used in various machines in order to transmit rotation accurately and synchronously. In these machines, idlers are commonly used to increase the angle of contact...

... indicates the sense of sliding by: (4) ε i = − V ⃗ 1 2 M i s ˙ y ⃗ / ‖ V ⃗ 1 2 M i ‖ The moment equations with respect to the pinion and gear axes of rotation lead to: (5) Cm = ∑ i = 1 Ncl [ − ε i s...

... error, which generally causes tooth separation at certain critical rotational speeds. The present paper discloses a method to analytically calculate which contact ratio to use in order to avoid tooth separation near a specific critical rotational speed. [S1050-0472(00)02604-0] The dynamic response...
