Development of Harmonic Drive Combining Four Arcs for Conventional Kinematic Application

open access: yesMachines, 2022
This paper proposes a modified harmonic cam, which is used to design a harmonic drive. Conventional harmonic drives using a sinusoidal cam type pertain to an elastic body concept and are thus difficult to design and evaluate.

The Capillary Waves’ Contribution to Wind-Wave Generation [PDF]

open access: yesFluids, 2022
Published theories and observations have shown that dissipation of gravity waves implies frequency downshifting of wave energy. Hence, for wind-waves, the wind energy input to the highest frequencies is of special interest. Here it is shown that this input is vital, because the direct wind energy input obtained by the air-pressure’s work on most ...
