EIA649_1A
This document is used for placing Configuration Management Requirements on Defense Contracts after being tailored by the Acquirer. When effectively and consistently applied, Configuration Management (CM) provides a positive impact on product quality, cost, and schedule. The planning and execution of Configuration Management (CM) is an essential part of the product development and life cycle management process. It provides control of all configuration documentation, physical parts and software representing or comprising the product. Configuration Management's overarching goal is to establish and maintain consistency of a product's functional and physical attributes with its requirements, design and operational information throughout its life cycle. When effectively and consistently applied, Configuration Management (CM) provides a positive impact on product quality, cost, and schedule.

EIA649C
When effectively and consistently applied, Configuration Management (CM) provides a positive impact on product quality, cost, and schedule. This standard is intended to assist in establishing, performing, or evaluating CM systems. CM is an integrated system of processes that ensure consistency of a product's performance, functional and physical attributes with its requirements, design, and operational information. The essence of CM, as portrayed in this consensus standard, is the common application of CM functions and their underlying fundamental principles, which have universal applicability across the broad spectrum of commercial and government enterprises. The standard provides an understanding of what to do, why a customer/suppler should do it, and when it is necessary to tailor the application of CM functions. This standard fulfills the important function of providing a rational basis upon which to apply good judgment in both planning for and executing CM across the enterprise.

Netlist Assurance Test Methods exist to assess microcircuit designs for maliciously added, removed, or modified functions detrimental to system operation. In the context of the Microcircuit fabrication design process, these methods will be used to analyze a computer aided design (CAD) representation of the microcircuit. The Netlist Assurance Test Methods discover vulnerabilities, undisclosed functions (e.g. "kill switch", paths to leak passwords, or triggers of malicious activity) and changes from the original specifications of the devices. These methods are intended to be used with standard verification methods that the implemented design has remained unchanged through the many transformations in the design flow.

Abstract This paper deals with the problems which emanates in front of society in developing electric vehicles. Aim of this paper is to prepare ways through which we can develop electric vehicle with efficiency (more than 60%). So that these electric vehicles can substitute I.C engine vehicles, which are main cause of environment pollution. To achieve that goal, various competitions are arranged in which one sitter kart develop to ease mechanical constraints and easily utilize innovations in kart. To develop kart various type of modelling and simulation were done on INVENTOR and ANSYS 14.0. Different type of test were also taken into account like Brake test, Speed test, Power test, Load test, and efficiency test. This paper also motivates student in developing vehicles so that they can excel their knowledge and assist in research of electric vehicles.

Abstract A simplified mathematical model of tandem suspension is presented to study the different parameters of tandem suspension. The equations of motion are compiled considering the system to be 3 degrees of freedom system, taking into accounts both oscillation and deflection of the leaf spring. The response characteristics for vibration isolation for the company test track road profiles at different speeds of the vehicle are calculated. The sensitivity of acceleration to variations in un-sprung masses and axle spacing is illustrated. Further, the usefulness of the model for studying the effect of shock absorber positioning on ride of tandem bogie suspension system is demonstrated.

Abstract Earth moving machines are steered using various steering methodology. Articulated steering mechanism is the most popular type of steering methods. It is actuated by hydraulic cylinders connected to the steering linkages. While the machine is deployed with articulated type steering, vehicle stability is proportionate to the steering velocity. Articulated steering provides two important features, shorter turning radius, allows front and back axle to be solid. Directional stability refers to a vehicle’s ability to stabilize its direction of motion against disturbances. Majority of earth moving equipment operates on basic cycle of Load-Haul-Dump. During each cycle, vehicle needs to be steered at least once. To optimize the machine performance for improved productivity it is essential to study the correlation between articulation speed and operational weight of the vehicle.

Abstract The excitation to a vehicle is from two sources, road excitation and powertrain excitation. Vehicle Suspension is designed to isolate the road excitation coming to passenger cabin. Powertrain mounts play a vital role in isolating the engine excitation. The current study focuses on developing an analytical approach using Low-Fidelity computer programs to design the Powertrain Mount layout and stiffness during the initial stage of product development. Three programs have been developed as a part of this study that satisfy the packaging needs, NVH requirements and static load bearing requirements. The applications are capable of providing the Kinetic Energy Distribution and Static Analysis (Powertrain Enveloping and Mount Durability) for 3-point and 4-point mounting systems and the ideal mount positions and stiffness for 3-point mounting systems.

Abstract In a typical passenger vehicle, there can be different types of noises generated which are broadly categorized as Interior Noise and Exterior Noise. The interior noise sources can be further classified into noises which can be Structure Borne or Air Borne. One of the major sources of both structure borne and airborne noise generation is the powertrain of the vehicle. The structure-borne noise and vibrations generated from the powertrain is usually transferred to the vehicle body through its attachment points to the body and the powertrain driveline. These induced body vibrations can sometimes cause the acoustic cavity of the passenger cabin to go into resonance which results in an annoying and disturbing noise for the passengers, called Booming Noise. Very often, one or more than one vehicle body panels show a dominant contribution in inducing this acoustic cavity resonance.

Abstract Vehicle dynamics is one of the important domains in the automotive field. It is the study of performance, ride and handling of the vehicle. The design of steering system, suspension system and front axle plays an important role in achieving good ride and handling characteristics of the vehicle. The wheel geometry is one of the suspension parameter that affects handling characteristics of the vehicle. Hence proper selection of wheel geometry angles such as caster, camber, toe, steering angle inclination and scrub radius plays an important role in suspension design. In this thesis work study has been conducted to analyze the influence of steering axis inclination and scrub radius on steering effort of passenger car. This study helps in selecting proper steering axis inclination and scrub radius with a goal of achieving lesser steering effort. Multi body dynamic model of selected passenger car has been built using ADAMS Car.
