SAE 2013 World Congress (2): Supplier Exhibits
New parts/powertrains improve efficiency and reduce fuel use
This report highlights the exhibits of auto parts/material suppliers at the SAE 2013 World Congress held on April 16-18, 2013, in Detroit, the U.S.
With the theme of the Congress this year, "Achieving Efficiency," participants introduced new technologies and parts/components to reduce vehicle weight, improve powertrain efficiency and reduce fuel consumption through increased electric operations in vehicles. Six OEMs set up their booths as in 2011 and 2012. Visitors slightly increased to approx. 10,000 this year from 9,000 last year and the number of parts/materials suppliers' booths increased slightly from last year to 170.
With the U.S. auto industry steadily recovering production and sales from Lehman's fall, the Detroit Auto Show, held in January at the same Cobo Hall, showed vibrant atmosphere. In contrast, the venue of the SAE World Congress this year was quiet, far from the Congress six or seven years ago, which was lively with many visitors, vehicles and parts/components exhibits.

ZF presents resin composite brake pedal and suspension strut of plastic and aluminum
ZF Group, Tier One strategic partner for the SAE 2013 World Congress, displayed lightweight parts/components using resin and aluminum at a large booth next to the event's host company, Chrysler Group LLC.
Lightweight strut module
ZF exhibited its prototype of a lightweight suspension strut wheel carrier module. ZF says that it will almost halve the suspension strut's weight by replacing current iron- and aluminum-made struts with those made from Glass Fiber Reinforced Plastics (GFRP), aluminum and High Tensile Strength Steel (HTSS) in order to reduce the unsprung weight, which will improve fuel efficiency and driving performance. For the prototype, ZF formed the strut mount and coil spring from GFRP and cast the strut as a solid aluminum part.
Currently, ZF is working on the design of the module so that it will be able to supply the parts in an assembled form, instead of shipping them separately to OEMs.

Hitachi Metal America displays a motor material with reduced rare earth
Neodymium magnets with reduced rare earth for electric motor application
For motors in HV/EV, electric power steering and other actuators, powerful neodymium magnets are used with expensive rare-earth dysprosium added for better temperature resistance. Hitachi Metals and an OEM have jointly developed a dysprosium vapor deposition diffusion technology named DDMagic that efficiently evaporates and diffuses dysprosium on to the boundaries of fine magnetic crystal grains and have successfully reduced the used amount of the rare earth.
Hitachi Metals also developed a ferrite powder magnet NMF-12 series to replace the neodymium powder magnet used in automotive starter-motors and home appliances' motors. Since 1989 it has produced the NMF-12 in the U.S. as well and is now developing the next-generation ferrite magnet. The new neodymium magnet with reduced dysprosium, currently produced only in Japan, will also be produced in the U.S. from 2013 to be supplied to motor manufacturers and other companies. Although Hitachi Metal has not announced officially, REMI Group and Toshiba are manufacturing motors for the magnet's automotive application in the U.S.
Hitachi Metal's "dysprosium vapor deposition diffusion technology to reduce dysprosium" won the Top 10 SAE 2013 World Congress Tech Awards.

Core Molding Technologies further reduces weight of composite resin fender
Core Molding Technologies Inc., a manufacturer of exterior body panels of medium- to heavy-duty trucks and other products, showcased its front fender under development. Parts molded by compressing thermosetting resin, using a Glass Fiber Reinforced Plastic(GFRP )called Sheet Molding Compound (SMC), are superior in stiffness and tensile strength to those made from thermoplastic resin such as the polypropylene(PP) and common engineering plastics, and lighter than parts made from steel sheet. SMC, therefore, is used for vehicles' body panels and small pickup truck beds, greatly reducing vehicle weight.
Core Molding Technologies developed Ultra Low Density SMC, a 1.18 sp.gr. density SMC, and molded a front fender for a medium-duty truck. At the Congress, it compared this prototype fender with its 1.9 sp.gr. SMC fender, available on the market. With almost the same appearance and quality, the reduced density SMC prototype weighed 10 lbs., 6 lbs. (approx. 3 kg) lighter than the current product.
In order to meet the tougher fuel efficiency requirements in the U.S., automobile and truck manufacturers are considering resin body panels and the use of composite in addition to larger application of aluminum, as means of vehicle weight reduction. According to Core Molding Technologies, physical properties of Ultra Low Density SMC are almost the same as currently available SMC. The company will compress SMC into front fenders, apply a primer and supply them to truck manufacturers. Commercial production of the lighter fender will start as early as the end of this year once its quality is confirmed.

Molding compound supplier BMCI introduces encapsulated sensor
Bulk Molding Compounds, Inc. (BMCI) presented a sensor encapsulated with a fiberglass reinforced thermosetting resin composite. A rotor position sensor for a transmission is used in the harsh environment of high temperature oil. BMCI used its product named BMC (as its company name), thermosetting Bulk Molding Compound superior in heat resistance, dimensional precision and chemical resistance, to encapsulate and injection-mold the rotor position sensor.
BMC causes no damage to the sensor or to the circuit board when molded into products. Dimensional changes of BMC products from low temperature to over 150℃ are fairly small, which provides an oil-tight and water-tight enclosure. According to BMCI, it is developing BMC- encapsulated sensors to be incorporated into engines and transmissions, jointly with about ten companies. At present, BMC-encapsulated electronics parts including sensors are used in HV/EV motors.

MicroHiL, off-line exhaust emission calibration device
FEV developed MicroHiL System, a system to simulate driving modes and real car performances in various environmental conditions such as high altitude and cold climates by using a virtual engine model connected to a real time processing ECU in order to search the optimized matching of ECU data. The system, originally developed for OBD (Onboard Diagnostics) system design, has been improved for the calibration of exhaust emissions.
At present, in order to search the optimized matching of ECU data acquired from environmental test laboratories and actual car driving, detailed ECU parameters are worked through various matching processes at laboratories and on the roads/circuits with real vehicles for final validation. With the MicroHiL, a virtual engine on the computer can try various engine revolutions, fuel injection volumes and simulated input signals from sensors to achieve the optimized matching for an engine and to conform exhaust emissions through semi-automatic processes. It is also capable of debugging the ECU data. The MicroHiL, therefore, reduces calibration times by up to 40%.
This portable MicroHiL weighs only about 30 to 40 lbs. It is a winner of the Top 10 2013 World Congress Tech Awards.

AVL presents battery and powertrain simulators
Battery testing simulator
AVL exhibited a simulation device for environmental testing of batteries on a test bench, without using an actual vehicle. AVL has battery-testing facilities in Europe and the U.S., where influence of thermal environment on batteries can be evaluated. AVL plans to upgrade the simulator by using various parameters including vehicle models, road conditions, and a driver's habits so that the device should be able to simulate a vehicle's actual running performances in the testing laboratory capable of thermal simulation from low to high temperatures. It will also add vehicle body distortion as a parameter and develop the simulation and testing device to be marketed as an integrated system with the software.
According to AVL, it has developed a lithium-ion battery pack for Mercedes-Benz concept car, EV Coupｅ-e 800.
|Battery testing device on a test bench||Monitor display on simulated conditions|
AVL also exhibited a powertrain simulator that directly connects motors to wheel axes to absorb engine drive and calibrates exhaust emission and fuel efficiency without using a chassis dynamometer. Compared to the system using a chassis dynamometer, with which wheels run on rollers set below the body floor, this simulator has four motors directly connected to front and rear wheel axes to operate the accelerator via computer. Unlike a dynamometer, it does not require an external engine-cooling fan.
This simulator calibrates exhaust emission and fuel efficiency as well as reproduces the actual driving situation on the test track on a PC, based on recorded engine revolutions, speeds and other conditions. The simulator has already been in use by European OEMs
