Grede is developing lightweight chassis, powertrain, and drivetrain components—including safety-critical systems—for several heavy-equipment manufacturers using a patented ductile iron alloy called SiboDur.
Turning circle greatly improved using a model implemented in MapleSim, holding out promise for better active-tilting designs that can improve vehicle maneuverability in congested cities.
To achieve weight savings in vehicles, OEMs and component suppliers are increasingly using ultra-high-strength steel, aluminum, magnesium, plastics, and composites. One strategy is to develop components using a multi-material concept. Ashok Leyland researchers used this approach when developing a bimetal brake drum with cast-iron inner ring and aluminum outer shell.
Ceramic matrix composite (CMC) use is up across the aerospace market, and among the fastest-growing trends in the global aviation industry. CMC material and component use in aircraft engines, specifically, is projected to double over the next five years, according to a new report from analysts at Stratview Research in Telibandha, India.
New compact utility leverages Fuji Heavy Industries' latest global platform for improved ride, handling, NVH attenuation and crashworthiness. But power and torque are lacking.
Equipped with Continental sensor technology, the height of ContiTech’s air springs can now be adjusted electronically, the internal pressure monitored and the internal temperature measured.
Lightweighting, direct fuel injection and turbocharging have been vital to achieving significant improvements in performance and efficiency; however, mechanical solutions alone cannot solve these challenges, says Dana CTO George Constand. Integrated electronics and software solutions are key for overall system design strategies.
Kenworth and Peterbilt vehicles will feature a new proprietary front axle using an innovative tapered kingpin roller bearing, beginning in the third quarter of 2017.
Endurica targets tire and rubber product developers with new software release. CAE software adds features for the analysis of rolling structures, self-heating, wrinkling, and cavitation.
Volvo Buses has started the global launch of its latest chassis powered by the 8-L Volvo engine. The Volvo B8R and B8RLE replace the top-selling Volvo B7R and B7RLE, which saw a production run exceeding 40,000 units and sales in 65 countries.
UQM Technologies signed a development agreement with Meritor to jointly develop E-axles for the medium- and heavy-duty EV commercial market, according to a February 2 announcement. Prototypes are expected by early fall of 2017.
To better inform and equip mobility engineers dealing with these challenges, SAE International has released a new book series from Juan R. Pimentel that explores automated vehicle safety concepts and technologies.
