Frequency analysis is often referred to as Fourier analysis but is that really true? The foundation is based on stationary and "Fourier signals." What happens if that is not the case? Modern FFT signal analyzers use very sparse sampling that is correct according to Shannon but what will happen when using time domain analysis. Many of the myths and frequent questions will be answered using a "user perspective" and rules of thumb will be given together with good methods to avoid large errors. After attending this session, a much better understanding in regards to pitfalls and proper methodology will be the outcome.

This document describes requirements for standardized processes (and associated technologies) that ensure type design data are retrievable and usable for the life of a type certificate (50+ years). These processes are primarily concerned with, but not limited to, digital type design data retained in threedimensional representations and associated data that is required for complete product definition, such as tolerances, specification call-outs, product structure and configuration control data, etc. This process standard includes process requirements for managing the evolution of technologies required to ensure the availability of the data for the life of the product. This data must be available to meet regulatory, legal, contractual and business requirements. This process standard is not intended to incorporate every company specific requirement and does not dictate specific organizational structures within a company.

Historically SAE has been concerned with nomenclature as an integral part of the standards development process. Guidelines for automotive nomenclature were written in 1916, were last revised in 1941, and were included in the SAE Handbook until 1962. The present diversity of groups working on nomenclature in the various ground vehicle committees led to the organization of the Nomenclature Advisory Committee under SAE Automotive Council.

Abstract There are variety of motors and generators/alternators being manufactured internationally, for variety of applications. It is a difficult task for the user to identify and select the type of motor /generator/alternator for a specific use, by the designer and ultimately the user is totally unaware of what is bought and why. There is a need to designate the motors and generators. So that by interpretation of the identification nomenclature of the motor or generator, its type can be judged. Whether it is a series motor, an induction motor etc, in case of motors. This will eventually make it easy for the manufacturer, the buyer and the consumer to identify the motor or generator type. So a universally accepted and followed identification nomenclature is required to be developed which will henceforth make dealing in motors and generators simpler for all. It will prove to be useful during troubleshooting.

Abstract This paper summarises the history of Rochdale Motor Panels and Engineering Ltd. (RMP), established in England after the Second World War, from its origins as a small car-repair business though to the manufacture of sports coupés utilising an innovative glass-fibre monocoque construction. The political climate which caused RMP and similar undertakings to develop and flourish in the 1950s and 60s is explained together with details of the three men who had the defining influence on the cars that were created. Products, including aluminium-bodied cars, produced primarily for racing, are described, leading into the introduction of glass-fibre construction which enabled a profitable transition into higher volume body and chassis manufacture, and ultimately completely assembled cars.

Abstract Total quality is becoming increasingly important for competitiveness. In order to achieve high quality, the requirements must be continuously compared with the results achieved in the process. This is done by means of measurement parameters and comparative values. The acquisition of the data requires appropriate measurement methods. The measurement methods and procedures have to be constantly developed in order to measure more precisely and to generate an even higher quality. Thus, the achieved product quality can be determined absolutely and relatively. If deviations from the planned quality parameters occur, the operator will be able to intervene immediately. The presented procedure is one of the noncontact (optical) measurement methods using CMMs, 3D scanners and 3D cameras. It is a combination of stereo photography and photogrammetry.

Abstract In recent years the automotive industry is facing unprecedented influx of new technology advancements and ever-increasing consumer demands for media, entertainment and connectivity applications. This drives the automotive industry to deliver the products at a faster pace, thereby reducing time to market which results in issues from end users and dealers. Automotive industries are striving hard to keep pace with these radical changes with increase in software and electronics which in turn necessitates a systematic and effective software engineering approach to deliver high quality product from the core embedded software industry. This paper details how embedded software projects are developed globally and customer issues are collected and analyzed. It also discuss about the method used for performing effective Root cause analysis for identifying the systemic issues and formulating the systemic improvement actions.

Abstract As the world's largest auto producer and consumer, China is both the most promising and complex market given the country's rapid economic growth, huge population, and many regional and segment preference differences. This research is aimed at developing data-driven demand models for customer preference analysis and prediction under a competitive market environment. Regional analysis is first used to understand the impact of geographical factors on customer preference. After a comprehensive data exploration, a customer-level mixed logit model is built to shed light on fast-growing vehicle segments in the Chinese auto market. By combining the data of vehicle purchase, consideration, and past choice, cross-shopping behaviors and brand influence are explicitly modeled in addition to the impact of customer demographics, usage behaviors, and attributes of vehicles.

Abstract Decision making in engineering design is complicated, especially when dealing with high-dimensional data. Modern software tools are able to produce a large amount of data while performing optimization studies. A typical optimization problem with many objectives may produce 100s or even 1000s of Pareto Optimal solutions. It is a challenge to analyze this data and make a decision about which design/s to choose for further testing or as a final design. To tackle the problem, two data analysis techniques are used in this paper. Partitive Clustering (PC) is used to locate groups of similar designs in the dataset while Principal Component Analysis (PCA) is used to reduce the dimensionality of the data and visualize it in two and three dimensions. Although these techniques can be used independently, when used together, they prove to be a tremendous help in decision making. This paper underlines the benefit of using these two methods together.

Abstract As combustion can vary widely between engine cycles if left uncontrolled, strict and robust control is required to meet optimum performance at different operating conditions. In this research, intelligent control techniques implemented on a Gasoline Direct Compression Injection (GDCI/GDI) engine. A research four cylinder 2.0 L GDI engine modeled with optimal control hardware that is frequently called as the conceptual Cybernetic intelligent GDI or ‘iGDI’ engine. The engine features Free Valve Actuation (FVA) hardware and precision fuel injector connected directly to the engine cylinder that found assistive for control flexibility by technical assessments. Then a mechatronic neural control approach is proposed and discussed with adaptive control techniques. Adaptive and predictive neural network control architectures developed for two distinct plant operation modes.

Abstract Automobile companies recognized the need to understand how customers use their vehicles. To this end, telediagnostic modules were installed on fleet vehicles, with the consent of the owner, to collect and store usage data. This data was uploaded to a server when the module was able to communicate via Wi-Fi. The volume of data is enormous. The size of a single vehicle file can be over six gigabytes, contain millions of records, and contain hundreds of millions of measurements. Each vehicle needs to be analyzed and the results from different vehicles combined to determine typical and extreme vehicle usage. With hundreds or thousands of vehicles to be analyzed, the analytic task is daunting. To analyze continuous data, like speed, frequency histograms have been used. It will be shown here that the cumulative percentile histogram provides better information and can display single and multiple vehicle usage patterns.

Abstract It is well known that spark ignited engine performance and efficiency is closely coupled to fuel octane number. The present work combines historical and recent trends in spark ignition engines to build a database of engine design, performance, and fuel octane requirements over the past 80 years. The database consists of engine compression ratio, required fuel octane number, peak mean effective pressure, specific output, and combined unadjusted fuel economy for passenger vehicles and light trucks. Recent trends in engine performance, efficiency, and fuel octane number requirement were used to develop correlations of fuel octane number utilization, performance, specific output. The results show that historically, engine compression ratio and specific output have been strongly coupled to fuel octane number.
