Fea Analysis And Optimization Of Differential Housing For Fatigue Stresses And Fatigue Test Design To Study Skin Effect In Ductile Iron, Swapnil A. Pandey

Dissertations, Master's Theses and Master's Reports

Automotive emission standards are getting more stringent day by day and governments worldwide are moving to reduce emissions from automobiles. In this scenario reducing the weight of automobile components becomes an important design objective to reduce emissions. A 10% reduction of weight in the complete automobile leads to 6-8 percent improvement in mileage (Mhapankar 2015). Also, powertrain components make up for approximately 27% of the total automobile weight and thus optimizing the design of components in the powertrain is an important task (Mhapankar 2015). Statistics show that 26% of component failures in automobiles are part of powertrain and 21% of …

Frontal Crash Analysis Of A Conformable Cng Tank Using Finite Element Analysis, Datta Sandesh Manjunath

Dissertations, Master's Theses and Master's Reports

The purpose of this study is to computationally model and analyze a Conformable Compressed Natural Gas (CNG) fuel tank for frontal crashes using Finite Element Analysis. Researchers have developed a CNG fuel tank, which is conformable, non-conventional and non-cylindrical. This tank increases cost efficiency, volumetric efficiency and cargo efficiency in CNG vehicle applications. A lightweight pickup truck (2015 Chevrolet Silverado) has been used to integrate the CNG tanks and field-testing has been conducted to demonstrate the application.

The report mainly focuses on the effective finite element modeling of the chassis, brackets and tanks using HYPERMESH and RADIOSS. The frontal crash …

The Effect Of Corrosion Defects On The Failure Of Oil And Gas Transmission Pipelines: A Finite Element Modeling Study, Jennet Orasheva

UNF Graduate Theses and Dissertations

The transportation of oil and gas and their products through the pipelines is a safe and economically efficient way, when compared with other methods of transportation, such as tankers, railroad, trucks, etc. Although pipelines are usually well-designed, during construction and later in service, pipelines are subjected to a variety of risks. Eventually, some sections may experience corrosion which can affect the integrity of pipeline, which poses a risk in high-pressure operations. Specifically, in pipelines with long history of operation, the size and location of the corrosion defects need to be determined so that pressure levels can be kept at safe …

Selective Resistive Sintering: A Novel Additive Manufacturing Process, Austin Bryan Van Horn

Graduate Theses and Dissertations

Selective laser sintering (SLS) is one of the most popular 3D printing methods that uses a laser to pattern energy and selectively sinter powder particles to build 3D geometries. However, this printing method is plagued by slow printing speeds, high power consumption, difficulty to scale, and high overhead expense. In this research, a new 3D printing method is proposed to overcome these limitations of SLS. Instead of using a laser to pattern energy, this new method, termed selective resistive sintering (SRS), uses an array of microheaters to pattern heat for selectively sintering materials. Using microheaters offers significant power savings, significantly …

3-Axis Automated Probe Traverse For Aerodynamic Testing, Tananant Boonya-Ananta, Ricky Wai, Zander Oostman, Teyvon Brooks

Mechanical Engineering

Our primary objective is to design, build, and test an automated traverse to hold measurement probes in Cal Poly’s low speed wind tunnel. The device should cause minimal flow disturbance. It’s movements must be able to cover eighty percent of the three-dimensional test section. The device should have a mounting point for interchangeable probes. The assembly is to be integrated with the current frame structure on the wind tunnel test section, and should allow very minimal deflection of the measurement probe. The user should be able to control the motion of the traverse via a computer interface which supports automatic …
