Analysis of novel geared linkage mechanisms

Journal of Advanced Mechanical Design, Systems, and Manufacturing, 2014
Two types of novel one-degree-of-freedom seven-bar geared linkage mechanism are presented. The proposed mechanisms consist of an elementary planetary gear train, a slider-crank mechanism or a Scotch yoke mechanism, and a slider-crank mechanism with a ...

Mechanics of Telson Ridges in Mantis Shrimp for Impact Analysis and Implications for Bioinspired Elastic Shell Designs

Advanced Functional Materials, EarlyView.
The mantis shrimp telson reveals how ridged biological shields control deformation under impact. Inspired by this architecture, telson‐inspired ridged curved shells transform ridge geometry and macroscopic curvature into bidirectional snap‐through, tunable stiffness, and enhanced hysteretic energy dissipation for multifunctional architected materials ...

A Kinematical and Dynamical Analysis of a Quadruped Robot

, 2011
In general, legged locomotion requires higher degrees of freedom and therefore greater mechanical complexity than wheeled locomotion. Wheeled robots are simple in general, and more efficient than legged locomotion on flat surfaces. Yet as the surface turns softer, wheeled locomotion becomes inefficient due to rolling friction.

Assessment of numerical differentiation methods for kinematic orbit solution of the GRACE mission [PDF]

, 2013
textThe historical method of precise orbit determination is a dynamic approach. However, with the improvement of GPS tracking data and associated tracking networks, two newer methods have been developed: reduced-dynamic and kinematic.

Mechanistic Origins of Chemo‐Mechanical Instability and Failure in Solid‐State Lithium‐Sulfur Electrodes

Advanced Functional Materials, EarlyView.
Conversion‐induced sulfur expansion generates strong mechanical constraints and localized stresses within solid‐state Li‐S cathodes. Heterogeneous solid‐electrolyte confinement creates tensile strain‐energy hotspots that govern particle cracking. Larger sulfur particles accelerate fracture, while higher porosity relaxes constraint and delays damage ...
