In-line, Elbow, and Tee Flanged Connectors for use with SAE J518-1/ISO6162-1 Components

2015-02-03
WIP
J518/4
This document standardizes the design of connector blocks used for joining SAE J518-1/ISO 6162-1 (Code 61) flange heads with other SAE J518-1/ISO 6162-1 (Code 61) flange heads with straight, elbow, and tee geometries. The blocks specified in this document are designed to provide for very compact installations. As a result, the tap depths specified in this document do not conform to those specified in SAE J518-1/ISO 6162-1 to allow for a minimal bend radius in the elbow and tee configurations. This document specifies both inch and metric configurations

Round Head Bolts

CURRENT
J481_199001
Round head bolts are made in two body styles: (a) A full size body, with a maximum diameter somewhat greater than the nominal diameter (not an SAE Standard except for ribbed neck bolts, Table 3); and (b) an undersize body, with a minimum diameter approximating the pitch diameter of the thread and a maximum diameter never exceeding nominal (SAE standard for all types except ribbed neck bolts). The body diameter of either style may be exceeded by a reasonable swelling or fin under the head, or under corners of the square necks, to the extent that serviceability is not affected.

Alignment of Nut Slots

1990-01-01
CURRENT
J484_199001
This method of gaging alignment of nut slots allows equal variations for location of the cotter pin hole in the bolt and location of slots in the nut. To inspect the nut, the slotted gage is inserted through the nut hole from the bearing surface of the nut. Alignment of slots is considered satisfactory if the gage pin can be slipped into the gage and nut slots without interference.

Visionary's Take: An Engineering Journey into the Marketplace (Part 3 of 3)

2017-10-12
Can you become a visionary or are you born one? How does a visionary capture an opportunity and makes it a successful business? Are engineers more qualified to solve technical problems or run companies? SAE's "The Visionary's Take" addresses these and many other questions, by talking directly with those who have dared to tackle difficult engineering problems, and create real-life products out of their experience. In these short episodes, Sanjiv Singh and Lyle Chamberlain, respectively CEO and Chief Engineer from Near Earth Autonomy, talk about their experience in creating a brand-new company in the UAV world. Founded in 2011, Near Earth Autonomy brought together a group of engineers and roboticists, looking for unconventional solutions to very hard logistics problems, presenting danger to human life. The answers were developed by pushing technology to a higher level, testing quickly and often, and keeping an open mind to alternative ways of framing engineering challenges.

A Study of PGM-Free Oxidation Catalyst YMnO3 for Diesel Exhaust Aftertreatment

2012-06-18
Manganese oxides show high catalytic activity for CO and HC oxidation without including platinum group metals (PGM). However, there are issues with both thermal stability and resistance to sulfur poisoning. We have studied perovskite-type YMnO3 (YMO) with the aim of simultaneously achieving both activity and durability. This paper describes the oxidation activity of PGM-free Ag/i-YMO, which is silver supported on improved-YMO (i-YMO). The Ag/i-YMO was obtained by the following two methods. First, Mn4+ ratio and specific surface area of YMO were increased by optimizing composition and preparation method. Second, the optimum amount of silver was supported on i-YMO. In model gas tests and engine bench tests, the Ag/i-YMO catalyst showed the same level of activity as that of the conventional Pt/?-Al2O3 (Pt = 3.0 g/L). In addition, there was no degradation with respect to either heat treatment (700°C, 90 h, air) or sulfur treatment (600°C to 200°C, total 60 h, 30 ppm SO2).

Spotlight on Design: Counterfeit Electronic Parts: Supply Chains at Risk

2015-04-15
“Spotlight on Design” features video interviews and case study segments, focusing on the latest technology breakthroughs. Viewers are virtually taken to labs and research centers to learn how design engineers are enhancing product performance/reliability, reducing cost, improving quality, safety or environmental impact, and achieving regulatory compliance. Just how prevalent is the problem of counterfeit electronic parts? What are the consequences of using sub-par components in safety or mission critical systems? The Federal Aviation Administration estimates that 2% of the 26 million airline parts installed each year are counterfeit, accounting for more than 520,000 units, maybe more.

Component Interoperability For Automotive Safety Issues

2012-05-22
There is a need to accelerate the automotive industry's alert notification and distribution process for quality, reliability, counterfeit, and safety issues that reside in specific electronic components or circuit card assemblies. This paper describes an alert procedure for an entire supply chain that can improve operational efficiency and reduce the costs associated with responding to and resolving those issues. Interoperability: Ability to work with each other. It is frequently unnecessary for separate resources to know the details of how they each work. But they need to have enough common ground to reliably exchange messages quickly without error or misunderstanding. Presenter William Crowley, QTEC Inc.

Development of High Strength Polymer Based Bearing for Automotive Parts under Boundary Lubrication

2012-05-23
Composite bearings of PTFE as the base material have been widely used for automotive parts. However, in recent years, due to downsizing, faster sliding speeds, and tendency to increase the bearing load with high performance, particularly for boundary lubrication conditions, the PTFE-based composite bearing is often worn, making it difficult to apply to some applications. A high strength polymer was selected as an alternative to PTFE base material, and the mechanical properties and performance in a start-stop test, reciprocating sliding test and seizure test were evaluated. Focusing on the characteristics of high strength, by applying a PEEK resin, in each evaluation, it was confirmed that superior performance was achieved compared with a conventional PTFE based composite bearing.

Optimization of Rule-Based Control Strategy for a Hydraulic-Electric Hybrid Light Urban Vehicle Based on Dynamic Programming

2012-05-29
This paper presents a low-cost path for extending the range of small urban pure electric vehicles by hydraulic hybridization. Energy management strategies are investigated to improve the electric range, component efficiencies, as well as battery usable capacity. As a starting point, a rule-based control strategy is derived by analysis of synergistic effects of lead-acid batteries, high efficient operating region of DC motor and the hydraulic pump/motor. Then, Dynamic Programming (DP) is used as a benchmark to find the optimal control trajectories for DC motor and Hydraulic Pump/Motor. Implementable rules are derived by studying the optimal control trajectories from DP. With new improved rules implemented, simulation results show electric range improvement due to increased battery usable capacity and higher average DC motor operating efficiency. Presenter Xianke Lin
