Automating The Design Optimization Of Vehicle Structures, William Bruce Mccormack
Automating The Design Optimization Of Vehicle Structures, William Bruce Mccormack
All Theses
structures, parametric design and finite element analysis are common tools for simulating structural behavior of systems under static and quasi-static loading. While these tools provide significant benefits over physical experimentation, cumbersome to set up and this time-consuming setup may need to be repeated many times while iterating on a design. The designers would therefore benefit from automating this design and analysis process so that they can explore the design space more efficiently or obtain higher performance design alternatives. To take full advantage of the benefits of this automation, it important to make the process as quick and easy as possible. …
Product And Process Based Assembly Time Estimation In Engineering Design, Michael Miller
Product And Process Based Assembly Time Estimation In Engineering Design, Michael Miller
All Theses
This thesis presents the research and development of two assembly time estimation techniques for the automotive industry. Both of these techniques are capable of being implemented early in the product life-cycle of a vehicle and require information available in this phase. Currently, assembly time estimation is performed after production has begun and is a tedious manual process requiring hours of motion-time method studies for each assembly activity. The techniques proposed in this thesis can both be performed prior to the start of production and are capable of being performed automatically after the initial mapping.
The first assembly time estimation technique …
Internal Combustion Engine Cooling Strategies: Theory And Test, John Chastain
Internal Combustion Engine Cooling Strategies: Theory And Test, John Chastain
All Theses
Advanced internal combustion engine thermal management systems can enhance overall engine performance through the use of computer controlled cooling system actuators. Existing ground vehicle cooling systems generally have performance limitations due to the fixed behavior of the wax-based thermostat valve and crankshaft dependent operation of the coolant pump and radiator fan. Upgrading the traditional thermostat valve, water pump, and radiator fan with actuators permit real time computer control for improved temperature tracking and reduced power consumption. In this paper, the benefits associated with advanced automotive cooling systems are experimentally investigated. A 4.6L engine with a real-time data acquisition and control …
