Simulating off-highway hybrids With customers squeezed by fuel costs, off-highway OEMs are showing some interest in developing hybrid equipment. CAE simulation tools are needed because of lack of experience with such devices. Their functional complexity requires control system simulation throughout their lives. A hose is a hose is a hose Researchers develop a method for the precise mounting of a hydraulic hose model. Integrity sensing for safety Researchers from Purdue developed a capacitance-based method for monitoring the integrity of tires, hoses, and other polymeric products during manufacturing and throughout the useful product life.

Lightpipe design According to Breault Research Organization, any off-highway instrument or control that needs illumination is a candidate for a lightpipe to take light from where it is generated to where it is needed. The biodiesel choice Experts from the Natural Biodiesel Board believe it is time to consider alternatives to the current fuel structure. One solution to rising fuel prices is the pursuit of biodiesel fuels. Understanding machining difficulties in gray iron Bosch Braking Systems' engineers look more closely than usual at iron brake rotor samples to give new insights into critical characteristics of the material. Caterpillar mining for customers With commodity prices low, Caterpillar wants to make mining as productive an enterprise as possible for customers.

A new Formula for racing The new Formula E series' electric racecars are intended to pioneer new technology for broader use in production, encouraging fans to think differently about the technologies they use. Production of satellite with first all-electric propulsion system advances Electric propulsion has been limited so far to small movements of the satellites once it is in its geostationary orbit. The Boeing 702SP innovation is its use of electric propulsion to raise the satellite from its launch-vehicle drop-off point to geostationary orbit. Using CAE to assess whining noise of electric powertrains To develop an electric powertrain with a minimum noise level and minimized whining it is necessary to have accurate CAE simulation and precise criteria to assess whining noise.

Clearing the air Sensors, diagnostics and controls advance to help trap emissions. Bringing the heat on cooling technologies Electronic controls, variable-speed fans cool engines, heat aftertreatment systems. 3D printing machines can't be built fast enough In the additive manufacturing world, the costs of components are dropping, the technology is becoming more reliable and parts are fabricated faster, allowing industries beyond aerospace to adopt additive technologies, says Oak Ridge Lab's Ryan Dehoff.

Putting lightweighting to the test Material laws and orientation information are coupled in a single finite element analysis to predict the performance of the hybrid composite beam under a dynamic three point bending load. Screens, cameras provide new look in cabs Video inputs are another option showing up on displays that increasingly offer touch control. Big performance in small packages By regulating light-duty engine variable speed fans based on heat rejection demands and ambient temperature, consistent power savings over the entire operating spectrum can be achieved.
