Rotating wheel dynamometer

Kistler's high-performance, six-component rotating wheel dynamometer model 9298A contains piezoelectric sensors, an electromagnetic angle encoder, and signal conditioning to transform rotating signals to a fixed coordinate system. Features of the unit include high-frequency response, adapters for a range of hubs and rims, triple-flange design for optimum temperature compensation, two force ranges for maximum signal resolution, 20x zoom capability on the vertical force signal, and an IP65 design that allows use in any weather condition. Wheel dynamometer data provide a basis for determining and optimizing tire characteristics, suspension tuning, design of active suspension, traction, and braking control.

42-V terminal

KonneKtech's RADSOK 42-V terminal - an adaptation of a hyperbolic configuration - is designed for high amperage applications and maximizes surface contact, ensuring the lowest possible millivolt drop. The improved contact resistance also guarantees lower temperature rises normally associated with high amperage applications. The RADSOK low insertion/extraction force allows for a tool-less assembly process and multiple mating/unmating without jeopardizing the integrity of the terminal. The round pin and cartridge design accomodates a 360° approach for multiple harness configurations. The range of 6 to 20 mm (0.24 to 0.79 in) from 100 to 800 A can provide a solution for most applications.

Electric power steering

The electric power steering (EPS) system from Koyo Steering Systems of U.S.A. consists of the steering column, integrated motor and controller, and rack and pinion gear. The system will be used in an upcoming SUV and be produced at Koyo's plant in Daleville, VA. The EPS design offers the advantages of modularity and reduced assembly costs for automakers; improved fuel economy and steering feel for drivers; and no need for hydraulic fluid, which eliminates leaks and helps the environment.

Lighting system tool

TracePro from Lambda Research aids in modeling surfaces with thousands or millions of repetitive features such as taillamp lenslets. The software features RepTile surfaces that can model many surface features in a virtual manner. The product can create very complicated models with a reduction in model size, preprocessing time, and ray-trace time compared to equivalent models with solid geometry. The surfaces accurately model today's complicated Fresnel and lenslet array structures used in taillamps, chimsels, and overhead automotive lighting systems.

Clip-on seals

EPDM clip-on seals from Lauren Manufacturing Co. feature rubber-encapsulated wire for easy application and enhanced flexibility; good compression set resistance; and weather-resistant, high-quality compounds designed for automotive door sealing systems. The seals clip on easily to exposed edges without adhesives, screws, or rivets. Applications include electrical enclosures, window seals, weather stripping, truck beds, tractor cabs, boat hatches, motor-home luggage compartments, and vehicle doors.

Copper-clad bimetallic cable

LTV Copperweld's automotive cable manufactured from bimetallic wire can reduce the weight and, in some cases, the size of automotive wiring. Copper-clad steel cable can be substituted for larger copper cable in leads that are sized for strength rather than conductivity, reducing the size and weight of wiring harnesses. Copper-clad aluminum cable can be substituted for copper cable to reduce the weight of power leads. Both metallic materials can reduce costs.

Air intake systems

Mahle Filtersysteme GmbH uses a new production method in the manufacture of intake systems, called multiprocess technology, particularly in those areas where other methods meet their limits. This new method is suitable particularly for V-engines, which require complex pipe geometries with minimum flow/power losses in a compact design. Production processes include blow molding, overmolding the flange, electromagnetic resistance welding, and sandwich welding of the plenum. The dimensional accuracy of the individual components is optimized by holding up the cores and cavities in the tools; the individual part tolerances are minimized by calibration in every stage of the production process.

Airbag test rig

MESSRING's horizontal airbag test rig makes it possible to conduct fully automatic tests on airbags with minimum space requirements, such as curtain tests, secondary impact simulations, large airbags for front and rear passengers, and tests conforming to ECE-R12. A software module based on CrashSoft3 incorporates the entire test process, including the comprehensive preparation, performance, and evaluation stages. The software can trigger up to four airbags at once with an accuracy better than 1 ms. An optionally unguided test body is projected at speeds up to 12 m/s (39 ft/s) at an airbag or at any other structure desired. In addition to the measurement of force and acceleration, the displacement and speed of the test bodies in guided tests can be generated using rebound analysis.
