“…The design optimization method based on finite element analysis is employed to optimize the dimensions of structural elements with a set of objectives and constraints. Design optimization has been used in many applications such as foot valves [2] and in-cylinder intake ports [3]. Similar Reliability-based design optimization has been put to use for an aircraft to minimize weight for a given level of safety [4].…”

The structural analysis of quad rotor frame is important since it has to withstand the forces due to aerodynamics and gravitational force due to the mounted weights. Design optimization based on finite element analysis provides an efficient methodology to meet the desired objectives related to structural elements. In the present study, design optimization based on response surface methodology has been used to optimize the shape of the arm used in the quad rotor. The objectives considered for the study include minimization of Von Mises stress and total deformation. The goal driven optimization used in ANSYS WORKBENCH has been employed for the study and arm has been redesigned to meet the set goals.

<div>Neutron diffraction is a powerful tool for noninvasive and nondestructive characterization of materials and can be applied even in large devices such as internal combustion engines thanks to neutrons’ exceptional ability to penetrate many materials. While proof-of-concept experiments have shown the ability to measure spatially and temporally resolved lattice strains in a small aluminum engine on a timescale of minutes over a limited spatial region, extending this capability to timescales on the order of a crank angle degree over the full volume of the combustion chamber requires careful design and optimization of the engine structure to minimize attenuation of the incident and diffracted neutrons to maximize count rates. We present the design of a “neutronic engine,” which is analogous to an optical engine in that the materials and external geometry of a typical automotive engine have been optimized to maximize access of the diagnostic while maintaining the internal combustion chamber geometry and operability of the engine. The high transparency of aluminum to neutrons makes it the ideal window material for neutron diagnostics, which allows the neutronic engine to be a truly all-metal engine with the same load and boundary condition capabilities of a modern downsized passenger car engine. The neutronic engine will enable 3D and time-resolved measurements of strain, stress, and temperature fields as well as phase transformation, texture, and microstructure throughout the metal components of the combustion chamber.</div>
