Dynamic Precipitation during High‐Pressure Torsion of a Magnesium–Manganese Alloy

Advanced Engineering Materials, EarlyView.
An ultrafine‐grained alloy is produced by high‐pressure torsion of solutionized Mg–1.35 wt% Mn. Precipitation of nanometer‐scale Mn particles during deformation provides pinning sites. This prevents the formation of a bimodal grain structure and results in a finer grain size than for pure Mg.

Transmission Error of Modular Robotic Joint

JSME international journal. Ser. C, Dynamics, control, robotics, design and manufacturing, 1994
This paper deals with the accuracy problem of a type of joint module with two rotary degrees of freedom used in a modular robot system. The error investigation concentrates on its differential gear mechanism. By dividing the gearing error into the gear transmission error due to effective eccentricity and the lost motion error due to effective backlash,

Understanding the Effect of Resistance Temperature Detector Temperature Controllers on Microstructural Alignment in Magnetic Freeze Casting

Advanced Engineering Materials, EarlyView.
The effect of temperature controllers that are commonly used in freeze‐casting is investigated in this work. Temperature controllers are observed to generate a voltage in the slurry. Microstructural alignment and ultimate compressive strength data show this voltage to interfere with the ability to align the microstructure using magnetic fields ...

Influences of circular runout errors and processing parameters for slotting on the accuracy of harmonic reducer

Journal of Advanced Mechanical Design, Systems, and Manufacturing, 2022
To investigate the influence of the manufacturing parameters on mesh behaviors for harmonic gear drive, the mathematical model of slotting the circular spline was established using kinematic method based on the tooth profile of the circular spline ...

Errors in Approximations to Maximum Transmissibility [PDF]

The Journal of the Acoustical Society of America, 1959
The error in using transmissibility at the undamped natural frequency in place of the maximum transmissibility of a single-degree-of-freedom system is less than 4% for all values of the damping ratio. The error is a maximum for a damping ratio of about 0.6 and decreases with both increasing and decreasing values of the damping ratio. The error in using

Chaotic Observer-based Synchronization Under Information Constraints

, 2005
Limit possibilities of observer-based synchronization systems under information constraints (limited information capacity of the coupling channel) are evaluated. We give theoretical analysis for multi-dimensional drive-response systems represented in the

Adaptable Tile‐Based Pneumatic Origami through Structurally Coupled Localized Actuation

Advanced Engineering Materials, EarlyView.
This article presents tile‐based pneumatic origami structures with rigid tiles and flexible fabric creases, achieving adaptable properties including morphing shape, selective multistability, and tunable stiffness. Independently pressurized folding bladders at each crease enable structurally coupled localized actuation of origami structures.
