Design Analysis of High Power Density Additively Manufactured Induction Motor

2016-09-20
2016-01-2061
Induction machines (IM) are considered work horse for industrial applications due to their rugged, reliable and inexpensive nature; however, their low power density restricts their use in volume and weight limited environments such as an aerospace, traction and propulsion applications. Given recent advancements in additive manufacturing technologies, this paper presents opportunity to improve power density of induction machines by taking advantage of higher slot fill factor (SFF) (defined as ratio of bare copper area to slot area) is explored. Increase in SFF is achieved by deposition of copper in much more compact way than conventional manufacturing methods of winding in electrical machines. Thus a design tradeoff study for an induction motor with improved SFF is essential to identify and highlight the potentials of IM for high power density applications and is elaborated in this paper.

A New Policy for COTS Selection: Overcome the DSM Reliability Challenge

2012-03-13
The increasing complexity of aerospace products and programs and the growing competitive pressure is facilitating the aggregation of small, medium and large enterprises of certain geographical regions into more integrated and collaborative entities (clusters). Clusters are by their same nature formed by heterogeneous companies, with huge differences not only in size but also for their core competences: such a diversity is a strength of the cluster, but it also increases its complexity. The purpose of this paper is to describe a benchmarking methodology that can be adopted to assess the performances of companies belonging to a cluster from different perspectives: economics and financials, competitive differentiators, specific know how, business strategies, production and logistic effectiveness, quality of core and supporting processes.

Spotlight on Design Insight: Sensors: Fluid Measurements and Avionics

2015-05-07
“Spotlight on Design: Insight” features an in-depth look at the latest technology breakthroughs impacting mobility. 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. The quality of fluids used in aviation, such as oil or fuel, is an extremely important safety issue. One way to reliably monitor fluids is through the use of special measurement sensors. In the episode “Fluid Measurements and Avionics” (9:13), an engineer at Meggitt demonstrates the capabilities of time-domain reflectometry sensors, explaining how they are assembled and used. The business case for monitoring oil and fuel degradation, and how to proactively take advantage of preventative maintenance is also explained.

Racing Green Endurance: An EV Record will focus on what a small team of ambitious and talented engineers can do when they have a dream! Back in 2009, a team of graduates from Imperial College London came together to do something radical to change the public perception of electric vehicles forever. They came up with the idea to design and build the world's longest range electric car, and then drive it down the longest and toughest road in the world; the 26,000km Pan-American Highway! Racing Green Endurance: An EV Record will share the story from start to finish, and will also focus on the technology used to achieve such a feat, with particular mention of the electric motors.

Enabling Exponential Growth of Automotive Network Devices while Reducing the Wired Communication Infrastructure with Security, Reliability, and Safety

2012-05-22
The CAN protocol has served the automotive and related industries well for over twenty-five (25) years now; with the original CAN protocol officially released in 1986 followed by the release of CAN 2.0 in 1991. Since then many variants and improvements in CAN combined with the proliferation of automotive onboard microprocessor based sensors and controllers have resulted in CAN establishing itself as the dominant network architecture for automotive onboard communication in layers one (1) and two (2). Going forward however, the almost exponential growth of automotive onboard computing and the associated devices necessary for supporting said growth will unfortunately necessitate an equivalent growth in the already crowded wired physical infrastructure unless a suitable wireless alternative can be provided. While a wireless implementation of CAN has been produced, it has never obtained real traction within the automotive world.

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 Scratch Resistant Clear Coat for Automotive

2012-05-23
Scratch resistance is one of the most important customer requirements for automotive painting. Scratches occur as a result of a load being imposed on a paint film, which then destroys or deforms it. In order to improve the scratch resistance properties of clear coat, a specially developed molecular that act to accelerate closslinking reaction was added to the clear coat main resin. This developed molecular facilitates closslinking between multiple molecules and creates an unprecedentedly fine molecular structure. The result is a soft, highly elastic, and durable clear coat with improved resistance to light and acid as well as enhanced deformation recovery properties. It requires no special maintenance, prevents luster degradation caused by surface scratches and helps to prolong new-car color and gloss. Developmental Clear Coat is introduced into the flagship of the Lexus range - the LS as Self-restoring Coat in 2009. Presenter Junya Ogawa, Developmental Center

Test Method for Seat Wrinkling and Bagginess

2012-05-22
This study evaluates utilizing an accelerated test method that correlates customer interaction with a vehicle seat where bagginess and wrinkling is produced. The evaluation includes correlation from warranty returns as well as test vehicle results for test verification. Consumer metrics will be discussed within this paper with respect to potential application of this test method, including but not limited to JD Power ratings. The intent of the test method is to aid in establishing appropriate design parameters of the seat trim covers and to incorporate appropriate design measures such as tie downs and lamination. This test procedure was utilized in a Design for Six Sigma (DFSS) project as an aid in optimizing seat parameters influencing trim cover performance using a Design of Experiment approach.
