Standard
EIA267C
This Standard defines a machine coordinate system and motion nomenclature for numerically controlled machines. It is intended to eliminate misunderstandings between manufacturers, programmers, and users of machine tools, to simplify programming, to facilitate the interchangeability of recorded data between machines of like configuration, and to simplify the training of programmers by the standardization of machine coordinate system and motion nomenclature. This Standard defines a machine coordinate system and machine movements so that a machine tool programmer can describe machining operations without having to know whether the tool approaches the workpiece or the workpiece approaches the tool. The rules contained in this Standard were developed with the cooperation of private industry and Government and are based on widely accepted industry practice and usage. They are also based, in part, on standards used in the international machine tool market.

The intent of this document is to define the methodology for suspect/counterfeit parts inspection using REME Analysis. The purpose of REME Analysis for suspect counterfeit part inspection is to detect misrepresentation or tampering of a part. REME Analysis can also potentially detect unintentional damage to the part resulting from improper removal of the part from assemblies, exposure to electrostatic discharge, exposure to radiation outside of acceptable limits (ionizing or high-power electromagnetic), or degradation. Improper removal of part from assemblies may include, but is not limited to, prolonged elevated temperature exposure during desoldering operations or mechanical stresses during removal. Degradation may include, but is not limited to, prolonged burn-in/testing, exposure to out-of-specification environmental conditions, or use outside of expected electrical tolerances.

Abstract A thorough bibliographic survey was carried out to collect literature-available information about blending octane numbers (BONs) of most widely used ethers by the refining industry (mainly MTBE and ETBE). The intention was to review the publicly reported BONs values, to suggest the most appropriate figures for future reference, while also understanding the causes of the differences. Summary tables feature all BON values, either explicitly reported in literature or calculated based on experimental results. Due to synergistic intermolecular interactions with hydrocarbons, BONs typically depend on base stock composition. The octane gain tends to grow as the paraffin content in the base stock increases. Moreover BONs tend to decrease as the octane numbers (ON) of the base stock increase.

Abstract This paper introduces the newly developed super sports car engine mounted in the new model NSX. A super sports car engine was newly developed to satisfy the high power performance required by the body package. Higher power and compactness were simultaneously achieved by selecting an engine displacement of 3.5 L and by using a V6 layout and a turbocharger. This enabled to mount a power train that combines a hybrid motor with a newly developed transmission in the rear of the body. The lubrication system uses a dry sump system capable of maintaining reliable lubrication in all possible super sports car driving scenarios. The combustion system uses high tumble-flow ports, a direct injection and a port injection system that increase power performance and thermal efficiency, emission reduction. To support the increased heat load due to higher power, a 3-piece water jacket is used around the combustion chamber and the exhaust ports.

Abstract EcoCAR is North America's premier collegiate automotive engineering competition, challenging students with systems-level advanced powertrain design and integration. The EcoCAR Advanced Vehicle Technology Competition series is organized by Argonne National Laboratory, headline sponsored by the U.S. Department of Energy and General Motors, and sponsored by more than 30 industry and government leaders. In the last competition series, EcoCAR 2, fifteen university teams from across North America were challenged to reduce the environmental impact of a 2013 Chevrolet Malibu by redesigning the vehicle powertrain without compromising performance, safety, or consumer acceptability. This paper examines the results of the EcoCAR 2 competition’s emissions and energy consumption (E&EC) on-road test results for several prototype plug-in hybrid electric vehicles (PHEVs). The official results for each vehicle are presented along with brief descriptions of the hybrid architectures.

Abstract The unit analysis methodology can be used for designing component or product in a product development process. This method may be used for designing the crush can, bumper beam, crush can long member, B-frame or A-pillar in frontal impact analysis. Unit assembly model technique can be effectively used in many CAE load cases to evaluate CAE simulations such as pedestrian impact analysis (ECE R78 / ENCAP), interior trim related head impact simulations (FMVSS201U), under run protection simulation for commercial vehicles (Front Underrun Protection Device ECE R93, Rear Underrun Protection Device ECE R58, Side Underrun Protection Device ECE R73), airbag deployment optimization etc. These CAE analyses correlate better with actual test. This paper gives idea about how the cost of product design can be reduced by using unit analysis. To reduce time of vehicle development such as cost of prototype, testing cost, optimization cost unit analysis is more economical.

Abstract The overall automotive industry is moving toward first time right test which in turn needs first time right analysis. This is due to the enormous pressure of cost, mass, time to market and availability of prototype vehicles for testing. Use of finite element methods enables to upfront predict the system behavior in operating conditions and evaluation of structural strength. In vehicle product development process, hood slam durability evaluation is one of the important tests for body closure structure. Current work showcases an effort made for developing virtual hood slam test. The virtual model consists of BIW, hood, hinge joint, interface like CRFM (cooling-radiator-fan module) and latch mechanism with spring preload. Analysis performed with LSDyna solver. An impact loading is applied by converting potential energy to kinetic energy, mimicking the hood dropping from a specified height on the hood latch.

Abstract Electrical Power and Signal Distributions System in a vehicle is the most important among the Automotive Electrical and Electronic systems. In fact any electrical or electronic systems are realized and are physically formed by the Electrical Wiring Harness. This is a system in itself with the set of wires and connectors connecting various devices to feed the power and act as physical channels for signal transmission and serial data communication. Thus, the Electrical Wiring Harness becomes huge complicated systems in a vehicle. Because of the number of wires, cables and the specific connectivity requirement the design and development will become very difficult. Further, the complexity is manifold due to number of harnesses in a vehicle and different operating conditions in different zones of the vehicle. The design and development of an Electrical Wiring Harness involves primarily the design of the electrical circuit. This is based on the vehicle architecture.

Abstract A three-motor hybrid system suitable for a super sports car was developed. This system features high power, light weight and high response, and has high cooling performance for high-load operation such as circuit driving. The power plant drives the rear wheels using the combination of a midship-mounted V6 twin-turbo engine, the direct drive motor of a hybrid system mounted directly on the engine, and a 9-speed dual-clutch transmission (DCT). The front wheels are driven by a twin-motor unit (TMU), and the size and weight of the Intelligent Power Unit (IPU) that supplies electric power to the TMU has been reduced to enable mounting behind the seats inside the cabin. In addition, the IPU uses air-conditioner cooperative cooling to enhance the cooling performance. As a result, assist is performed even during high-load operation.

Abstract Based on equivalent static loads method (ESL), a nonlinear dynamic topology optimization is carried out to optimize an automotive body in white (BIW) subjected to representative legislative crash loads, including frontal impact, side barrier impact, roof crush and rear impact. To meet the crashworthiness performances, two evaluation indexes are defined to convert the practical engineering problems into mathematic optimization problems. The strain energy is treated as the stiffness evaluation index of the BIW and the relative displacement is employed as the compliance index of the components and parts.
