Engine and Brake Friction

CurtisEllzey — Thu, 08 May 2008 15:28:00 GMT

The Motorsport Engineering Program at CSU set out to design and build a floating liner engine to be used for the measurement of internal friction. A floating liner engine is one for which the cylinder liner is mounted in such a way that any rigid contacts are intermediated by force sensors. By equipping the engine this way it is possible to measure the forces acting on the cylinder liner due to the motion of the piston. The brake friction dynamometer was developed to test heat transfer and braking efficiency as well as perform brake bedding (initial transfer of brake pad material onto rotor). The system enables the testing and evaluation of calipers, friction materials and rotors, including rotor wear and friction modification treatments.

At the PhD-level the students focus on advanced design and analysis. Key faculty are involved in the motorsport engineering program with specialties including vehicle dynamics, composites/chassis structures, and computational fluid dynamics. Current graduate research projects at the 14,000 square foot research facility include topics such as turbocharger control and optimization, composite materials insertion into IC engine technology, CFD of cylinder ports, valve dynamics studies, vehicle torsional stiffness, natural frequency approaches to spring/damper tuning, racetrack simulation, and more. Engineers educated to take on lead roles in the motorsport industry and on professional race teams are a rare commodity. CSU’s Motorsport Engineering program is a pipeline to a well trained employee pool that is prepared for the challenges of vehicle design, setup and race preparation.

FPGA-controlled Vocoder Beatboxing

CurtisEllzey — Mon, 05 May 2008 14:47:00 GMT

Intelligent DAQ is multifunction data acquisition that features user-defined, onboard processing for complete flexibility of system timing and triggering. Instead of a fixed ASIC for controlling device functionality, intelligent DAQ uses an FPGA-based system timing controller to make all analog and digital I/O configurable for application-specific operation. You can configure the FPGA chip by creating LabVIEW block diagrams with the National Instruments LabVIEW FPGA Module. National Instrument's Vineet Aggarwal demonstrates this functionality with a new vocoder application and some excellent beatboxing skills.

The Electric Giraffe

CurtisEllzey — Wed, 30 Apr 2008 15:04:00 GMT

Based on Tamiya's little model of a walking giraffe, the Electric Giraffe is a 17 foot tall robotic giraffe that borrows this toy's walking mechanism. The giraffe uses a small 12 horsepower engine burning propane gas to charge system batteries that power a 3 horsepower electric motor that only needs 1.5 horsepower to move the giraffe, using a true hybrid fuel-engine-generator-electric motor design. The motor gives its power to a "hydrostatic transmission", providing a continuously variable "analog" speed control. Currently the giraffe has about 500 watts of on board audio power, slated to be expanded to at least 2000 watts in the future, as well as a multitude of programmable lights controlled by Kontron embedded systems.

Large Natural Gas Engines

CurtisEllzey — Mon, 21 Apr 2008 13:54:00 GMT

The Engines and Energy Conversion Laboratory at Colorado State University has a 15 year history in developing products which improve engine efficiency and reduce harmful emissions from engines as small as 1 hp to as large as 2500 hp. As the quest for alternative fuels continues, new sources of gaseous fuels are emerging. These consist of both synthetic natural gas (coal gas, reformed natural gas) and biomass derived gases (wood gas, biogas). This project explores the use of alternative gaseous fuels in traditional natural gas engines.

Rapid Prototyping

CurtisEllzey — Thu, 03 Apr 2008 13:32:00 GMT

Rapid Prototyping (RP) – technology allows 3D-printing of arbitrarily shaped structures, directly from computer-aided design (CAD) data. It has traditionally been used to produce only passive mechanical parts. A team at Cornell University has developed compact, automatic Solid-Freeform Fabrication systems, or “fabbers”, which can build almost any kind of object – not merely passive mechanical parts, but complete devices, ready to use right out of the machine.
