“The Creation, Development and Implementation of a Lean Systems Course at Oakland University, Rochester, MI”

2005-04-11
2005-01-1798
Countless articles and publications3,4,5 have documented and proven the efficacy, benefits and value of operating within a lean system. Furthermore, there exists common agreement amongst leading organizations successfully implementing a lean system that in order to do so it must take into consideration the entire enterprise, that is, from supplier to customer and everything in between6. One of the core issues this paper addresses is when the optimal time is to train and educate the people who currently have, or will have, influence over the ‘enterprise’.

“Targeting Consumer Needs in the Perfect Storm: Changing the Automotive Lifestyle”

2008-10-20
2008-21-0038
The intersection of changing lifestyles and evolving transportation needs finds smart USA well positioned for launch in 2008 during one of the most competitive periods in U.S. automotive history. In a zero sum market with new global entrants competing for single points of share, where quality levels have been redefined and fractions of points separate the best from the challengers, lifestyle awareness, innovation and product positioning become the differentiators. Simply adding features has left some with hefty investments and confused consumers. Bigger is not always better. More is not always desirable. The real opportunity for new entrants to the US market may be defined within niche markets where changing lifestyles allow for the emergence of new segments. Today, smart USA has surfaced as a clear example of right product, right place, right time.

“Standardizing the Datasheet” Towards Auto-Code Generation Efficiency

2009-04-20
2009-01-0270
Software programs in non-application areas such as Board Support Packages, Hardware Abstraction Layers, signal processing and data acquisition are more or less very standard and common across many applications. These form a major part of the “platform” software, which changes very little. However, it is seen that many a time, efforts are spent resolving issues in the hardware dependent layers rather than concentrating on the application at hand, despite the fact that the software controlling the hardware has been developed many times. There are many reasons why this section of the software is rewritten many times over: different coding standards, different software architecture and layering concepts, the dreadful cut-and-paste methods, and so on. Introduction of a tool-based code configurator and generator eliminates access to the code and focuses on configuring a pre-written set of SW procedures. Advantages: Standardization, reuse and high levels of productivity.

“Sky Hooks” for Automobiles

1935-01-01
350109
IN this paper the authors present some experimental results obtained by using the analysis outlined by Prof. James J. Guest before the Institution of Automobile Engineers, in 1926. To make the experimental work more understandable, they present the essential points of Professor Guest's analysis. Professor Guest begins his analysis of the movements of a car body with the simplest set of conditions and presents a graphical as well as an algebraic solution. He then includes one additional factor after another in his analysis until the principal factors in car suspension are included. After all factors are considered, the essential structure of the simple analysis is retained. The authors' efforts at the experimental determination of the moment of inertia of passenger cars were started in January, 1932, on Sir Charles Dennistoun Burney's “tear-drop” design with which he visited leading American manufacturers.

“Second-Generation” SAE 5W-30 Passenger Car Engine Oils

1986-10-01
861515
High performance lubricant additive systems have been developed to formulate SAE 5W-30 passenger car engine oils which meet current and anticipated requirements of the North American original equipment manufacturers. The trend in North America is to recommend SAE 5W-30 oils that not only meet the API SF requirements for gasoline engines (“first-generation” oils), but also meet the stringent API CC requirement for light duty diesel engines (“second-generation” oils). Furthermore, the engine builders have issued “world specifications” for motor oils which incorporate additional “second-generation” SAE 5W-30 characteristics, such as enhanced API SF limits, improved fuel efficiency, an increased margin of bearing protection, and lower finished-oil phosphorus levels. The additive systems described herein exceed API SF and CC requirements as well as “second-generation” performance hurdles.

2002-01-3353
Dodge wanted to promote the new Dodge Ram 1500 pick-up truck and regain a presence in NASCAR and was looking for a venue that would accommodate this presence. NASCAR launched the NASCAR Craftsman Truck Series (NCTS) in 1995 and Dodge joined the series. This paper will cover the history of Dodge Motorsports Engineering presence in this series. The engineering objective was to develop an organization that would meet the corporate goals. The initial problem was that Dodge hadn't participated in a NASCAR series since 1978 and had no recent experience. The conclusion was that Dodge Motorsports Engineering could be competitive in NASCAR series racing.

In automotive electronics on-board diagnostics does the fault diagnosis and reporting. It provides the level of robustness required for the control electronics against various faults. The amount of diagnostic information available via on board diagnostics are depends on the type of vehicle. Pre-supply fuel pump is the component in the common rail hydraulic system. It pumps the fuel from the fuel tank to the inlet valve of the high pressure fuel pump. Electronic control unit synchronizes its operation with high pressure fuel pump. A dedicated driver module in the ECU controls the operation of pre-supply fuel pump. The driver module consist of an ASIC with internal voltage, current monitoring modules for the fault diagnosis and the pre-drivers to control external HS and LS power stages. The software part of the OBD programmed in the internal memory of the ASIC. The “Rds_on” of the power MOSFETs are used for the fault detection purpose.

“Projection-by-Projection” Approach: A Spectral Method for Multiaxial Random Fatigue

2014-04-01
2014-01-0924
This paper presents a fatigue criterion based on stress invariants for the frequency-based analysis of multiaxial random stresses. The criterion, named “Projection-by-Projection” (PbP) spectral method, is a frequency-based reformulation of its time-domain definition. In the time domain PbP method, a random stress path is first projected along the axes of a principal reference frame in the deviatoric space, thus defining a set of uniaxial random stress projections. In the frequency-domain approach, the damage of stress projections is estimated from the stress PSD matrix. Fatigue damage of the multiaxial stress is next calculated by summing up the fatigue damage of every stress projection. The criterion is calibrated on fatigue strength properties for axial and torsion loading. The calculated damage is shown to also depend on the relative ratio of hydrostatic to deviatoric stress components.

“Personal Integrity” and Man-Machine Integration

1982-02-01
821348
A sense of “personal integrity” blocks pilot use of new information about how he thinks. Research on human performance under stress done over the past fifty years indicates increased rigidity and regression to earlier learned behavior in high stress, and in low Stress a shift in attention to any domestic situation or on the job controversy which is of higher stress than that of the job at hand, all without the pilot's knowledge. Informal surveys of commercial pilot training and commercial pilot attitudes towards these studies indicate that the study findings directly confront learned cultural responses. Pilot and trainer reactions prevent the information from being adequately investigated or formally taught. The findings are not written into training manuals and pilots who are informally given the information do not have adequate access to the knowledge when it is needed.

“POSSIBILITIES IN THE FIELD OF DRY LUBRICANTS”

1958-01-01
580278
Research information on solid lubricants has been compiled for consideration in the possible use of such materials in aircraft electrical equipment. Solid lubricants are capable of lubricating at the maximum temperatures (600° F) for aircraft electrical equipment. Many solids that adhere well to metals may be useful lubricants; those with layer-lattice structure usually give low friction. Solid lubricants are most commonly used as bonded films but the use of fluid carriers and surface reaction products have considerable merit.

“LABORATORY OCTANE RATINGS WHAT DO THEY MEAN?”

1957-01-01
570099
The results of several anti-knock studies are discussed in this paper. Road anti-knock performance for 1000 fuel blends covering the years 1940 to 1957 have been investigated. The laboratory Research octane numbers of these fuels covered the range from 80 to 105. The fuels were evaluated in 46 cars representing a cross-section of the automotive products for these years. The objective of these investigations was to determine the practical application of the laboratory to road octane rating relationships, and the effect of vehicles, and operating conditions on these relationships. The results show that there is a valid correlation between laboratory and road octane ratings. The relative importance of Research and Motor octane ratings on road performance is influenced by make of car, engine speed, throttle position, and distributor advance characteristics. It also indicated that aromatics improve, whereas olefins reduce high speed Modified Borderline ratings.

“IQTC: A Practical and Unified Index for the Evaluation and Continuous Improvement of Suppliers”

1999-12-01
1999-01-2989
Considering that the opening of the national market varies at the mercy of the economy and the government, Mercedes-Benz do Brasil launched a program to support the local suppliers. Within this program, one may enhance the tool IQTC (Commercial and Technical Qualitative Index). One deals with an index that will enable the supplier to exactly know in which scores he is “weak”, where he is strong and where he has to improve. The transparency regarding the information has to be complete. The general composition of the index will be presented with its criteria and requisites in which the various areas of Mercedes-Benz participate in, with additional details for the IQDP (Quality Index in Product Development), that is the subindex prepared by the Development area. Some practical results involving the evaluation of suppliers will also be shown, whose results, however, will not be nominally quoted.

“IQDP: The Challenge of the Development Area to Evaluate its Suppliers”

2001-03-05
2001-01-3975
In the work presented to SAE in 1999: IQTC: a Practical and Unified Index to Evaluate the Continuous Improvement of Suppliers, we showed that the Development Area is one of the chapters inserted into the evaluation process of suppliers and answers for an evaluation called IQDP (Quality Index in Product Development). The present work objective is to show the difficulties found in the implementation, solutions and improvements that are being used to outline a better supplier evaluation. Such a control within a universe of 350 suppliers (directly connected to production) being evaluated by 400 persons, in a natural process, is not an easy task. Collecting information about the difficulties faced to evaluate a supplier and the supplier claims to obtain an answer in reply to the attributed scores, took us to the search of the adequate computerized technology that would allow us to group the interests of work methods that would comply with the diverse demands involved.
