Kinematics and Performance Analysis of the 2T1R/1T2R Reconfigurable Decoupled Parallel Mechanism

Applied Sciences
Based on the reconfigurable revolute (rR) pair, a reconfigurable decoupled parallel mechanism is proposed, which is composed of three serial chains. Traditional serial chain 1 and 2 are of types PRRR and URC, respectively, where P denotes a prismatic ...

Slip Localization Intensification Mediated by Grain Boundary Sliding in a Polycrystalline Nickel‐Based Superalloy

Advanced Engineering Materials, EarlyView.
The temperature dependence of fatigue behavior in nickel‐based superalloys is investigated through high‐resolution measurements of plastic localization. While increasing temperature reduces localization and enhances fatigue performance in René 88DT, Inconel 718 exhibits a sharp degradation at intermediate temperature due to intensified slip ...

Kinematic analysis of kinases and their oncogenic mutations – Kinases and their mutation kinematic analysis

Molecular Informatics
AbstractProtein kinases are crucial cellular enzymes that facilitate the transfer of phosphates from adenosine triphosphate (ATP) to their substrates, thereby regulating numerous cellular activities. Dysfunctional kinase activity often leads to oncogenic conditions.

Current Status and Challenges in Data Collection for Aerospace Coatings Deposited by Plasma Spraying

Advanced Engineering Materials, EarlyView.
An innovative approach has been integrated into the GRENAT project to optimize plasma spraying and coating performance. Raw materials are accelerated and melted in the plasma generated by torches, creating coatings. Monitoring sensors collect process data which are combined with ex situ characterization data.

Model-Based Design of the 5-DoF Light Industrial Robot

Robotics
With the application and rapid development of light industrial robots, it is vital to accelerate the prototype design to fulfill the demands of shortening the robot’s production cycle, owing to rapid update iterations. Since the traditional design method

Representation of the kinematic topology of mechanisms for kinematic analysis [PDF]

Mechanical Sciences, 2015
Abstract. The kinematic modeling of multi-loop mechanisms requires a systematic representation of the kinematic topology, i.e. the arrangement of links and joints. A linear graph, called the topological graph, is used to this end. Various forms of this graph have been introduced for application in mechanism kinematics and multibody dynamics aiming at ...

Experimental Characterization and Constitutive Modeling of the Effect of Prior Inelastic Strain on the Viscoplastic Behavior of AD730 at 700 °C

Advanced Engineering Materials, EarlyView.
This study shows that superalloys used in aircraft engine disks become much more prone to deformation at high temperatures if they have been strained during manufacturing. This effect increases with the level of prior strain but eventually reaches a limit.

Kinematic path analysis of kinematically indeterminate systems

KSCE Journal of Civil Engineering, 2016
Kinematically indeterminate systems are geometrically unstable. Considering that there is only tiny elastic deformation in the process of the mechanism motion, the method to simulate kinematic paths of kinematically indeterminate systems without considering elastic deformation is studied in this paper.

From Shear to Sound: Mechanics–Acoustics Mapping of TPMS Lattices

Advanced Engineering Materials, EarlyView.
Triply periodic minimal surface (TPMS) lattices are mapped across mechanical and acoustic performance, revealing that descriptors validated in compression fail under shear. First‐time comparison with trusses included. A transition from porous to resonance‐driven absorption emerges at 25% density.

Precision multi-degree-of-freedom laser therapy system for excision of eschar over burn wound

工程科学学报, 2019
Early escharotomy in cases of severely burned patients can reduce infection and shorten the course of treatment. From the treatment effect, the quality of escharotomy operation is critical to the postoperative recovery of burn patients.
