Design Features And Optimization Of Profile Extrusion Dies, Abhishek Sai Erri Pradeep
Design Features And Optimization Of Profile Extrusion Dies, Abhishek Sai Erri Pradeep
Dissertations, Master's Theses and Master's Reports
This report deals with design of dies used in the plastic extrusion industry. The design methodology for extrusion dies has evolved over the years with advancement of computing technology. However, the design process is still heavily dependent on the experience of the die designer, and hence is still considered to be more of an art than science. Even for an experienced designer, the time required to design the die and perform consecutive fine tuning iterations is high. In this report, a proprietary optimization code for extrusion dies, .developed by Plastic Flow LLC, was tested and shown to be advantageous over …
Mechanical Testing Of Fused Filament 3-D Printed Components For Distributed Manufacturing, Nagendra Gautam Tanikella
Mechanical Testing Of Fused Filament 3-D Printed Components For Distributed Manufacturing, Nagendra Gautam Tanikella
Dissertations, Master's Theses and Master's Reports
Fused filament fabrication (FFF)-based open-source 3-D printers offer the potential of decentralized manufacturing both in developing and developed countries. Unfortunately, a severe lack of data and standards relating to material properties and printed components limit this potential. This thesis first investigates the mechanical properties of a wide-range of FFF materials and provides a database of mechanical strength of the materials tested. The results demonstrate that the tensile strength of a 3-D printed specimen depends largely on the mass of the specimen, which provides a means to estimate the strength of 3-D printed components. Then this information is used to evaluate …

Design, Fabrication And Analysis Of An Auxiliary Power Unit On A Heavy-Duty Truck To Power The Hvac Systems Of The Truck During Driver Off-Duty Conditions, Rohan Milind Kalurkar
Dissertations, Master's Theses and Master's Reports
Currently, one of the biggest challenges the world is facing is energy insufficiency. One of the contributors to energy consumption in United States are the idling semi-trailer trucks. In May 2001, President Bush issued The National Energy Policy in which he directed The Environmental Protection Agency (EPA) and Department of Transportation (DOT) to reduce the idling of trucks. This was done in order to reduce energy consumption by lowering fuel consumption and emissions coming out of semi-trailer trucks in the United States of America.
This project deals with the efforts of installing an Auxiliary Power Unit (APU) as a device …
Design And Fabrication Of A Suspension Rig, Abhijith Geo Philip
Design And Fabrication Of A Suspension Rig, Abhijith Geo Philip
Dissertations, Master's Theses and Master's Reports
Owing to its placement under the vehicle body, the suspension system is one of the parts of the vehicle which are difficult to comprehend completely, albeit being a vital component. For demonstrating the working of a suspension system, a physical model in which one can actually see the movement of all the components would be a great tool. A Mustang II independent front suspension system was purchased from Heidts Engineering Performance and a rig that can emulate some of the real world situations of vehicle suspension action was designed and fabricated. All the components are accessible and conditions like bounce, …
