Mechatronics for Mars and Beyond

Mechatronics for Mars and Beyond"Mechatronics" is now a buzz word and apparently the solution to everything engineering-wise. That includes mechanical, electrical/electronic, hydraulics/pneumatics, sensors, communications, etc. — software and firmware notwithstanding. Mechatronic robots are invading, not our Earth as the latest Transformer movie depicts, but on Mars where NASA's Rover searches for life. This same technology is being adapted into the family auto, even washing clothes without measuring the size of the load. This mechanical-electronic concept is rapidly finding its way into all kinds of engineering designs.

Tour de France Still Needs Steel

Tour de France Still Needs SteelNew technology debuting at the Tour de France includes "old" materials like good old reliable steel — neither advanced carbon composites nor titanium apparently could compete. Many of the top-of-the-line racing bikes use ultra-lightweight materials, but new designs using bushings, bearings, and gears still rely on old faithful steel.

Bullish for Bearings

Bullish for BearingsBearings are the unsung heroes in so many mechanical designs — yet without ball, roller, or plain bearings, planes don't fly and cars don't hit the road. A recent report by the Freedonia Group notes that bearing demand is increasing at 3.1% annually, contributing to a $10.4 billion market by 2011.

Materials Fulfill All Functions

Materials Fulfill All FunctionsGrading value and price advantages, convenience, performance characteristics, longevity, and even availability are only a few of the factors that engineers consider when specifying gasket materials. To help users decipher which material is best for the application, a new brochure rates 10 advanced materials and describes how they can handle the toughest jobs.

In Search of Failsafe Seals

In Search of Failsafe SealsOne infamous failure — the O-rings in the Challenger space shuttle — constantly reminds engineers of how important seals really are. This primer on seal failure analysis examines the three ways a seal can fail and how to analyze the environment, design, and elastomers contributing to common failures. A multiplicity of specific topics addresses most of the possible permutations.

Understanding a Goodman Diagram

Understanding a Goodman Diagram Interpreting a Goodman Diagram, used in the manufacturing of springs, graphically approximates the fatigue limit for a given spring design. Based on S-N data from extensive testing, such diagrams can be invaluable. Read the design tips and suggestions to learn how to avoid spring fatigue.

"Swab the Decks" Reliability Resource

'Swab the Decks' Reliability ResourceThe U.S. Navy's Naval Surface Warfare Center has published the "Handbook of Reliability Prediction Procedures for Mechanical Equipment." It encompasses springs, bearings, seals, gaskets, and virtually any kind of mechanical equipment. The in-depth treatise shows how to identify critical failure modes and thereby optimize mechanical equipment performance.

The Ultimate Robotic Tools

The Ultimate Robotic ToolsThe Martian rovers, Spirit and Opportunity, have been exploring the landscape of Mars for more than three years. One onboard tool is of the rock-abrasion variety. It's designed to grind into Martian rocks and allow the rovers' sensors to look inside and see what's there. That should be interesting.

Multifunctional Mechanical "Fish"

Multifunctional Mechanical 'Fish'Call it an adjustable wrench plus a screwdriver and then add LED lighting. Wait a minute, you need to add a multiplicity of other functions: a high-carbon stainless steel blade, a carabiner (quick disconnect system), and a money clip. Strap on the Guppie, and you're good to go with the best of scouts.

'New' vs Conventional Engineering"New" vs Conventional Engineering

Engineering school teaches that conventional engineering is based on physical laws that are described by equations and dimensionally homogeneous. But what if a new theory of engineering could show that problems are solved with the variables separated rather than combined? You may want to read more about the concept of nonlinear engineering phenomena and judge for yourself.
