Identification of unbalance characteristics of rotating machinery using a novel optimization-based methodology
(Springer, 2022-02-26)
In this study, a novel optimization-based method is proposed to determine the parameters of a rotating unbalance in a rotor-bearing system. For that purpose, the weighted sum of squared difference between the analytical ...
Experimental and numerical modal characterization for additively manufactured triply periodic minimal surface lattice structures: Comparison between free-size and homogenization-based optimization methods
(Wiley, 2023-06)
Homogenization-based topology optimization (HMTO) is one of the most extensively used grading methods to generate functionally graded lattice structures (FGLs). However, it requires a precharacterization of the lattices, ...
A novel design framework for generating functionally graded multi-morphology lattices via hybrid optimization and blending methods
(Elsevier, 2023-05-25)
Owing to its excellent mechanical properties, triply periodic minimum surfaces (TPMS) lattice structures have recently gained more interest in engineering applications. The superior properties of these structures make it ...
Effect of build parameters on the compressive behavior of additive manufactured CoCrMo lattice parts based on experimental design
(MDPI, 2022-07)
Due to their high specific strength, toughness, and corrosion and wear resistance characteristics, CoCrMo alloys are widely used in different industries and applications: wind turbines and jet-engine components, orthopedic ...
Enhancing the performance of Piezoelectric Energy Harvester under electrostatic actuation using a robust metaheuristic algorithm
(Elsevier, 2023-02)
This study proposes a novel shape optimization methodology based on evolutionary algorithms to maximize the harvesting energy from piezoelectric energy harvester stimulated by the β-emitted radioisotope. The parametric ...
Topology optimization-based design and development of a compact actuator with a high torque-to-weight ratio for quadrupeds
(IEEE, 2022)
This paper presents the design, development, and testing procedures for a compact actuator with a high torque-to-weight ratio, generally aimed to actuate legged robots, e.g., quadrupeds. The main goal of designing the ...
The effect of interlaminar graphene nano-sheets reinforced e-glass fiber/ epoxy on low velocity impact response of a composite plate
(IOP Publishing, 2018-05)
In this study, we compare the inter-laminar effect of graphene nano-sheets (GNSs) and CNTs on the single and multiple dynamic impact response of E-glass fiber reinforced epoxy composite (GFEP). In the comparisons, raw GFEP ...
Numerical assessment of the factors controlling the acoustic response of wind turbine blades
(Canadian Acoustical Association, 2019)
The blades of wind turbine are the most critical parts of the wind turbine system, which contribute to noise generated by wind turbine due to excitation from air streams across them. In this numerical study, the effect of ...
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 ...
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 ...
