Design Optimization Of Pressure Vessel With Particular Design Considerations, Artik Patel
Design Optimization Of Pressure Vessel With Particular Design Considerations, Artik Patel
Mechanical and Aerospace Engineering Theses
The pressure vessels in industries are generally designed with a high safety factor because the rupture of a pressure vessel can be extremely dangerous. A vessel that is poorly designed or ineffectively designed to handle high pressure pose a very significant threat to life and property. Because of this, the design and verification of pressure vessels is governed by design codes specified by the ASME (American Society of Mechanical Engineers) Boiler and Pressure Vessel Code. The objective of this thesis work is to minimize the total weight of a real-world pressure vessel structure subjected to stress constraints specified by the …
Modeling The Impact Of Battery Degradation Within Lifecycle Cost Based Design Optimization Of Heavy-Duty Hybrid Electric Vehicles, Ashish P. Vora
Modeling The Impact Of Battery Degradation Within Lifecycle Cost Based Design Optimization Of Heavy-Duty Hybrid Electric Vehicles, Ashish P. Vora
Open Access Dissertations
The optimal design of hybrid electric vehicle (HEV) powertrains from a systems perspective is critical to realize the maximum benefits for a given application. This is particularly true in the heavy-duty vehicle space where the major challenges are: (i) greater emphasis on economic viability, (ii) reluctance to take on risk associated with new technologies, and (iii) numerous diverse applications that preclude a one-size-fits-all approach to hybrid-electric powertrain design. Past studies on HEV powertrain design have either ignored battery degradation, or failed to holistically capture its impact from a lifecycle cost perspective. The focus of this effort is the development of …

Design Optimization Of Sandwich Core, Mohammad Tauhiduzzaman
Open Access Theses & Dissertations
Ultralight sandwich structures comprising of low-density core with stiff facings have attracted significant research interest for their considerable weight saving applications. The aircraft industries are focusing on decreasing the structural mass to lower the manufacturing and operating costs. Design analysis of the sandwich cores using finite element analysis has been developed as a promising concept to feature sandwich structures with maximum strength, stiffness, and reduced weight. To obtain multifunctional behavior of sandwich panels, a profound investigation of geometrical and mechanical properties in the transverse plane is required because it is very susceptible to any kind loadings. Structural optimization is one …
