Semi-solid casting is a near-net shape casting process that is capable of producing extremely high-quality castings. It differs from all other casting processes as it does not use fully liquid metal to produce the castings, instead using a feed material that is preferably about 50% solid and 50% liquid.
The challenges for the off-highway industrial engine supplier goes beyond simply meeting ever more stringent emissions regulations in Europe. Their engine designs also need to minimize total cost of ownership while delivering power and fuel efficiency in a worldwide market.
No area of the third-generation Tucson crossover utility vehicle was left untouched by Hyundai engineers, but particular attention was placed on re-engineering the chassis for improved ride and handling, and importantly, better NVH characteristics. The CUV employs a dual-reinforcing panel rear wheelhouse design, which optimizes panels that are prone to vibration, resulting in a 109% increase in rigidity.
The automaker is developing a camera-based lighting system that can automatically widen dipped beams at road junctions and roundabouts. It is also researching infrared image triggered spotlighting and an intelligent GPS linked system.
The 2017 GT development program has begun testing in southeastern Michigan, with the exotic American supercars running “naked” as they rack up miles amid daily commuter traffic. Automotive Engineering encountered and photographed one of the off-tool prototypes recently.
TE Connectivity’s aluminum COPALUM Lite sealed terminals and splices provide fast, easy terminations for aerospace applications, while reducing weight up to 60%. The company's INSTALITE RoHS-compliant braid, which offers high electrical performance over a range of frequencies, is up to 50% lighter than traditional braid.
Ian Callum joined Jaguar in 1999, where he and his team created, among others, the R-Coupe, RD-6, C-X75, and C-X17 concepts. His Jaguar production model list spans, chronologically, the last generation XK (2006), followed by the XF, XJ, and the F-Type, in coupe and convertible forms. Now, Callum has led his team to create the new XF and future Jaguars.
New PL72, PL83, and PL87 pipelayers feature differential steering and an electronically controlled hydraulic system that places total control of lifting functions into a single joystick. A dash-mounted LCD display provides onboard diagnostic information for the operator.
The PD400 has a common electronic control architecture that supports the full suite of JDES advanced motor control software to optimize performance of permanent magnet or induction motors in hybrid electric applications.
