Download or read book Vehicle Battery Fires written by Greg Barnett and published by SAE International. This book was released on 2017-01-15 with total page 186 pages. Available in PDF, EPUB and Kindle. Book excerpt: Battery Fires: Why They Happen and How They Happen was written to assist those interested in this type of incident understand how automotive fires develop, spread and the damage they cause, using both deductive and inductive reasoning. The main focus of the book resides in looking at differences in failure modes between DC and AC systems, general types of battery and electrical failure modes leading to fire, how to interpret electrical fire, determination of the primary failed part, and other skills the investigating engineer will require to perform technical failure mode analysis. However, some fires have consumed the evidence to the point where a determination cannot be made with any degree of certainty. In this instance, evidence will be quite limited, and the analysis will have its limitations and should be included in the discussion as such. In some cases, a “cause undetermined” report is all the evidence will support. Battery Fires: Why They Happen and How They Happen is a unique title which brings together the theory and the practice of correctly evaluating the root causes of unexpected and dangerous automobile fires.

Download or read book Aerospace Predictive Maintenance written by Charles Edwin Dibsdale and published by SAE International. This book was released on 2020-12-30 with total page 140 pages. Available in PDF, EPUB and Kindle. Book excerpt: Aerospace Predictive Maintenance: Fundamental Concepts, written by longtime practitioner Charles E. Dibsdale based in the UK, considers PdM a subset of Condition Based Maintenance (CBM), and must obey the same underlying rules and pre-requisites that apply to it. Yet, PdM is new because it takes advantage of emerging digital technology in sensing, acquiring data, communicating the data, and processing it. This capability can autonomously analyse the data and send alerts and advice to decision makers, potentially reducing through-life cost and improving safety. Aerospace Predictive Maintenance: Fundamental Concepts provides a history of maintenance, and how performance, safety and the environment make direct demands on maintenance to deliver more for less in multiple industries. It also covers Integrated Vehicle Health Management (IVHM) that aims to provide a platformcentric framework for PdM in the mobility domain. The book discusses PdM maturity, offering a context of the transformation of data through information and knowledge. Understanding some of the precepts of knowledge management provides a really useful and powerful perspective on PdM as an information system. On the other hand, Aerospace Predictive Maintenance: Fundamental Concepts also discusses disadvantages of PdM and shows how these may be addressed. One of the fundamental changes PdM implies is a shift from deterministic black-and-white thinking to more nuanced decision making informed by probabilities and uncertainty. Other concerns such as data management, privacy and ownership are tackled as well. Aerospace Predictive Maintenance: Fundamental Concepts covers additional technologies, such as the Industrial Internet of Things (IIOT) that will result in proliferation of cheap, wireless, ultra-low-power sensors, and will transform PdM into a more economical option. The book brings in the future possibilities of nano technology, which can be used for new sensors, micro-robotics for inspections and self-healing/repairing of systems which can be intergrated with PdM.
Download or read book Lightweight Low Cost Automotive Data Acquisition and Telemetry System written by and published by . This book was released on 2005 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Dynamically, testing small, lightweight automobiles can be very difficult on a limited budget. Several quality data acquisition systems exist that are designed for automotive applications, but most are large cumbersome units that require an AC power inverter. It would not be possible to use one of these systems on a small lightweight vehicle, like a Formula SAE racecar. A device powered from a 12 volt DC power supply is required for this type of application. Also, typical data acquisition systems are far too bulky and costly to be fitted to a Formula SAE vehicle. As with any system, recording actual operating conditions will provide useful information, leading to system improvements. In order to achieve these goals, several data acquisition with telemetry systems were investigated. The most interesting system, Dataq DI-720-EN and Linksys wireless router, were purchased and characterized through a barrage of testing. The system was first characterized by logging a random signal and transferring the data through a typical wired setup. The system was then methodically tested in the lab with Ethernet wired and wireless data transfer methods. The data acquisition and telemetry system was also tested dynamically, on the 2004 Bearcat Motorsports FSAE vehicle, using wireless data transfer methods. The testing results were promising, with minimal signs of poor data. Some gaps were seen in the data, but were deemed insignificant for the majority of potential testing. Lastly, several likely improvements are discussed.
Download or read book Modification and Validation of an Automotive Data Processing Unit Compessed Video System and Communications Equipment written by and published by . This book was released on 1997 with total page 50 pages. Available in PDF, EPUB and Kindle. Book excerpt: The primary purpose of the "modification and validation of an automotive data processing unit (DPU), compressed video system, and communications equipment" cooperative research and development agreement (CRADA) was to modify and validate both hardware and software, developed by Scientific Atlanta, Incorporated (S-A) for defense applications (e.g., rotary-wing airplanes), for the commercial sector surface transportation domain (i.e., automobiles and trucks). S-A also furnished a state-of-the-art compressed video digital storage and retrieval system (CVDSRS), and off-the-shelf data storage and transmission equipment to support the data acquisition system for crash avoidance research (DASCAR) project conducted by Oak Ridge National Laboratory (ORNL). In turn, S-A received access to hardware and technology related to DASCAR. DASCAR was subsequently removed completely and installation was repeated a number of times to gain an accurate idea of complete installation, operation, and removal of DASCAR. Upon satisfactory completion of the DASCAR construction and preliminary shakedown, ORNL provided NHTSA with an operational demonstration of DASCAR at their East Liberty, OH test facility. The demonstration included an on-the-road demonstration of the entire data acquisition system using NHTSA'S test track. In addition, the demonstration also consisted of a briefing, containing the following: ORNL generated a plan for validating the prototype data acquisition system with regard to: removal of DASCAR from an existing vehicle, and installation and calibration in other vehicles; reliability of the sensors and systems; data collection and transmission process (data integrity); impact on the drivability of the vehicle and obtrusiveness of the system to the driver; data analysis procedures; conspicuousness of the vehicle to other drivers; and DASCAR installation and removal training and documentation. In order to identify any operational problems not captured by the systems testing and evaluation, the validation plan also addressed a short-term pilot research program to manipulate DASCAR under operational conditions using "naive" drivers. The effort exercised the fill capabilities of the data acquisition system. ORNL subsequently evaluated and pilot tested the data acquisition system using the validation plan. The plan was implemented in full at the NHTSA East Liberty, OH test facility, and was carried out as a cooperative effort with the Vehicle Research and Test Center staff. ORNL determined the reliability of the sensors and systems by exercising DASCAR For one vehicle type, ORNL evaluated systems reliability over a continuous period of 30 days with particular attention paid to maintenance of calibration and data integrity.
Download or read book Application Layer Diagnostics written by Truck Bus Control and Communications Network Committee and published by . This book was released on 2006 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The SAE J1939 series of recommended practices are intended for light- and heavy-duty vehicle uses on- or off-road as well as appropriate stationary applications which use vehicle-derived components (e.g. generator sets). Vehicles of interest include, but are not limited to: on- and off-highway trucks and their trailers, construction equipment, and agriculture equipment and implements. The purpose of these documents is to provide an open interconnect system for on-board electronic systems. It is the intention of these documents to allow electronic devices to communicate with each other by providing a standard architecture. J1939-73 identifies the diagnostic connector to be used for the vehicle service tool interface and defines messages to accomplish diagnostic services. California-regulated OBD II requirements are satisfied with a subset of the specified connector and the defined messages. Diagnostic messages (DMs) provide the utility needed when the vehicle is being repaired. Diagnostic messages are also used during vehicle operation by the networked electronic control modules to allow them to report diagnostic information and self-compensate as appropriate, based on information received. Diagnostic messages include services such as periodically broadcasting active diagnostic trouble codes, identifying operator diagnostic lamp status, reading or clearing diagnostic trouble codes, reading or writing control module memory, providing a security function, stopping/starting message broadcasts, reporting diagnostic readiness, monitoring engine parametric data, etc.This SAE Recommended Practice has been updated to support manufacturers' new requirements, and new On Board Diagnostic (OBD) regulatory requirements for light duty, medium duty and heavy duty vehicles. These cover the needs of US EPA, US CARB, EU, and World Wide Harmonization of OBD. The following updates made: APPENDIX G, listing non-OBD fault management narratives, DM22 (Individual Clear/Reset of Active and Previously Active DTC), DM23 (Previously Active Emission Related Faults), DM24 (SPN Support), DM25 (Expanded Freeze Frame), and DM26 (Diagnostic Readiness 3), a revised definition for DM6, and updates to the DM1 for lamp flashing and a fixed 1 second update rate, DM27 (All Pending DTCs), DM28 (Permanent DTCs), DM29 (Regulated DTC Counts), DM30 (Scaled Test Results), DM31 (DTC to Lamp Association), DM32 through DM52, and the addition of 2 new FMIs (FMI 20 Data Drifted High, and FMI21 Data Drifted Low).
