Design and development of a powered upper limb exoskeleton with high payload capacity for industrial operations
(IEEE, 2020-09)
This study presents the hardware development and low level controller structure of an upper-body exoskeleton that is equipped with high torque-to-weight ratio actuators. It is intended to be used in industrial applications. ...
Effect of external stress on the post-aging mechanical properties of rolled magnesium alloys
(TANGER Ltd., 2020)
In the current study the effects of conventional aging and stress aging on the microstructure and mechanical behavior of warm rolled AZ31 magnesium alloy were investigated. Tensile experiments revealed that the ultimate ...
Numerical analysis of solar radiation effects at indoors with internal partitions and external solar shades
(International Solar Energy Society, 2020)
A numerical study is conducted to couple natural convection in an office space with thermal radiation due to solar radiation. The study specifically investigates the effect of partitions located between desks of the office ...
Rapid heating and cooling chamber for a photonics junction measurement system
(IEEE, 2020)
Since many industrial applications require heat treatment processes or validation tests under certain ambient temperatures, thermal design is a key issue to be considered in order to ensure fast heating and cooling ...
A high-torque density compliant actuator design for physical robot environment interaction
(IEEE, 2020)
Compared to the traditional industrial robots that use rigid actuators, the advanced robotic systems are mobile and physically interact with unknown and dynamic environments. Therefore, they need intrinsically safe and ...
Co-ex: A torque-controllable lower body exoskeleton for dependable human-robot co-existence
(IEEE, 2019-06)
In this paper, we present our research study concerning the design and development of an exoskeleton that aims to provide 3D walking support with minimum number of actuators. Following a prior simulation study, the joint ...
Influence of warm rolling and aging on the microstructural evolution and mechanical behavior of AZ31 magnesium alloy
(American Institute of Physics Inc., 2019)
The microstructural evolution and tensile properties of AZ31 after warm rolling and different aging methods and conditions were investigated. The warm rolling was conducted on the as-received AZ31 after homogenization at ...
Effect of processing parameters on the strength of keyhole free friction stir spot aluminum welds
(American Institute of Physics Inc., 2019)
Intermediate layer friction stir spot welding (IL-FSSW) is a new solid-state welding method appropriate for making spot joints, particularly in light-weight materials, especially notable on account of the weight saving ...
3-D dynamic walking trajectory generation for a bipedal exoskeleton with underactuated legs: A proof of concept
(IEEE, 2019-06)
This paper presents a framework to address three dimensional (3-D) dynamic walking for a bipedal exoskeleton with underactuated legs. To achieve this goal, the framework is constructed via a trajectory generator and an ...
Effect of heat treatment on the corrosion-fatigue of NiTi shape memory alloy
(American Institute of Physics Inc., 2019)
Nickel Titanium (NiTi) shape memory alloys have been considered convenient implant material due to their distinguished properties including superelasticity (SE), shape memory effect (SME) and biocompatibility. Among these ...
