Shock and Vibration, Volume 2021, Issue 1, 2021., 2021 Compared with dual‐mass flywheel (DMF) and DMF with simple‐type centrifugal pendulum vibration absorber (CPVA), DMF with bifilar‐type CPVA has a better damping performance in the whole speed range of engine. The related research mainly focused on local models, such as dynamic model of DMF and dynamic model of CPVA, and the effect of the curvature path ...

Simulation Research on Trapped Oil Pressure of Involute Internal Gear Pump
Mathematical Problems in Engineering, Volume 2021, Issue 1, 2021., 2021 The main structure of an internal gear pump consisted of an internal gear pair, including an internal gear and an external gear. The internal gear pump had oil trapping phenomenon like other hydraulic gear pumps. In order to solve the oil trapping phenomenon of involute gear pump with internal meshing tooth profile, in this paper, the mathematical ...

The Computational Fundamentals of Spatial Cycloidal Gearing [PDF]
, 2009 The tooth flanks of bevel gears with involute teeth are still cut using approximations such as Tredgold’s and octoid curves, while the geometry of the exact spherical involute is well known. The modeling of the tooth flanks of gears with skew axes, however, still represents a challenge to geometers.

Seismic control of flexible rocking structures using inerters
Earthquake Engineering &Structural Dynamics, Volume 49, Issue 14, Page 1519-1538, November 2020., 2020 Summary Allowing flexible structures to uplift and rock during earthquakes can significantly reduce the force demands and residual displacements. However, such structures are still susceptible to large deformations and accelerations that can compromise their functionality.
