Reconfiguration Analysis of an RRRRS Single-Loop Mechanism
Robotics, 2018 The paper deals with the reconfiguration analysis of the single-loop variable degree-of-freedom (DOF) RRRRS mechanism composed of five links connected by four revolute (R) joints and one spherical (S) joint.

dynoGP: Deep Gaussian Processes for Dynamic System Identification
International Journal of Adaptive Control and Signal Processing, EarlyView.This work introduces a novel class of deep models for system identification, dynamical deep Gaussian processes, which combine the strengths of data‐driven methods, such as those based on neural network architectures, with the ability to output a probability distribution for uncertainty representation.

Passive Shock Isolation Utilising Dry Friction
Shock and Vibration, 2017 A novel shock isolation strategy for base excited system is presented by introducing a two-degree-of-freedom model with passive friction, where the friction is applied to an attached mass instead of directly to the primary isolated mass.

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 ...

Parametrical Investigation of Piezoelectric Energy Harvesting via Friction-Induced Vibration
Shock and Vibration, 2020 In this work, piezoelectric energy harvesting performance via friction-induced vibration is investigated numerically. A one-degree-of-freedom friction system with a piezoelectric element is proposed, to study the piezoelectric energy harvesting via ...

Novel piezoelectric crawling robot with multiple degrees of freedom
AIP Advances, 2021 Traditional ultrasonic motors can usually produce either linear or rotational motion. Piezoelectrically driven structures with multiple degrees of freedom require two or more ultrasonic motors, and the manufacturing process is associated with some ...

Advanced Engineering Materials, EarlyView.Thermomechanical fatigue tests of laser beam powder bed fusion (PBF‐LB) Inconel 718 show that the additively manufactured material reaches almost the lifetimes of conventionally‐rolled material under no‐dwell conditions. Introducing dwell times at the maximum temperature markedly reduces the lifetimes due to pronounced grain boundary sliding associated
