Robust Design

Engineers are taught to create designs that meet customer specifications. When creating these designs, the focus is usually on the nominal values rather than variation. Robustness refers to creating designs that are insensitive to variability in the inputs. Much of the literature on robustness is dedicated to experimental techniques, particularly Taguchi techniques, which advocate using experiments with replications to estimate variation. This course presents mathematical formulas based on derivatives to determine system variation based on input variation and knowledge of the engineering function.

Factory Man

2009-02-16
Factory Man is about James Harbour and the epic struggle of the U.S. auto industry to catch up to Japan in quality and productivity. Harbour is a former manufacturing executive who, partly by chance, became the first U.S. expert to study Toyota's operations in Japan. Harbour's consulting firm, Harbour & Associates has gained worldwide recognition for its annual public studies of factory productivity. The Harbour Report is the essential annual scorecard of who is winning the productivity race in the U.S. In 1981, Harbour reported that Toyota could offer a small car for sale in the U.S. at a production cost of $1,500-$1,700 less than the Detroit automakers at that time, a cost advantage of about 30 percent. The impact on Detroit was atomic, and launched the painful, historic effort by the Big Three to catch up, which continues today. James Harbour's story, blunt and accessible, includes a detailed description of how Detroit went astray, beginning right after World War II.

AIR9975
This document will address techniques or methods that have been used within the industry to address the problem of engine stability margin accounting when combinations of distortion types exist in an aircraft installation. Its focus is combining temperature, planar wave, and swirl distortion with time-variant spatial total pressure distortion. Example methodologies will be presented along with example cases where co-existing distortions have been evaluated. It will also address the areas where the industries' knowledge base is lacking (experimental data or computational methods) and the future work that is needed for methodology development in these areas. This document is viewed to be updated every five years as more information (data either experimentally or analytically) becomes available.

The Modeling of Mold Filling in Structural Reaction Injection Molding

1996-04-01
91A118
The main use of FRC in automobiles, with the exception of a few specialized low volume vehicles, has been until now in semistructural parts. One of the most promising process in development today, that may play major role in future structural composite fabrication, is based on SRIM technology. The rapid and extensive introduction of this process goes also through the development of deeper theoretical knowledge of the process and the development of computer simulation to aid mold design and choice of proper processing parameters. To contribute SRIM advancement, a preliminary model has been developed for viscosity changes, extent of the reaction and temperature rises, associated with the mold filling stage, as well as a simple software to evaluate the pressure drop through different combinations of reinforcements.

1996-04-01
91A089
A wide variety of choices confront the potential user of finite element modeling (FEM) for sheet forming analysis. In the first part of this paper, a brief summary of the basic formulations available and sample references to them are provided. Several kinds of finite element models have been developed for analyzing sheet forming operations at OSU and in the Center for Net Shape Manufacturing. These variations began with in-plane FEM and grew into 3-D versions. In the second part of this paper, some key conclusions from these developments will be summarized. More recently, a section analysis program (SHEET-S) has been prepared and transferred to industry. The capabilities and limitations of SHEET-S will be presented in greater detail, including comparisons with experiments and industrial trials.

1988-03-01
871231
In this paper a computer simulation study on the effects of steering parameters on lateral dynamics of the guideway bus to contribute to a development practice of designing optimum steering control system are dealt with. A stability limit of vehicle lateral motion is analyzed and an emphasis is laid on the effects of moment of inertia of a conventional steering wheel and lateral elasticity of the guide rail which have proven to reduce the critical vehicle speed. It is pointed out conclusively that a normal bus equipped with additional simple guidance equipments can be guided smoothly on a simple guideway at adequately high vehicle speed.
