Optimization of Near-Field Wireless Power Transfer Using Evolutionary Strategies

The parameter space for power transfer by nearfield, magnetically coupled, half wavelength coil resonators was explored by evolving the coil shape using an evolutionary strategy and method of moments antenna analysis. The starting coil shapes were solenoid, which were evolved to enhance the power transfer between multiple coils. Through the use of an appropriate fitness function and tuned searc...

Multi-Objective Evolutionary Algorithms for Low-Thrust Orbit Transfer Optimization

We address the problem of optimizing a spacecraft trajectory by using three different multi-objective evolutionary algorithms: i) Non-dominated sorting genetic algorithm, ii) Pareto-based ranking genetic algorithm, and iii) Strength Pareto genetic algorithm. The trajectory of interest is an orbit transfer around a central body when the spacecraft uses a lowthrust propulsion system. We use a Lya...

Isogeometric Topology Optimization of Continuum Structures using an Evolutionary Algorithm

Topology optimization has been an interesting area of research in recent years.  The main focus of this paper is to use an evolutionary swarm intelligence algorithm to perform Isogeometric Topology optimization of continuum structures.  A two-dimensional plate is analyzed statically and the nodal displacements are calculated.  The nodal displacements using Isogeometric analysis are found to be ...

Multi-objective Optimization of web profile of railway wheel using Bi-directional Evolutionary Structural Optimization

In this paper, multi-objective optimization of railway wheel web profile using bidirectional evolutionary structural optimization (BESO) algorithm is investigated. Using a finite element software, static analysis of the wheel based on a standard load case, and its modal analysis for finding the fundamental natural frequency is performed. The von Mises stress and critical frequency as the proble...
