The military's new off roader: The
The U.S. Army and Marine Corp needed a new personnel carrier, one
that could handle the rocky terrain of Afghanistan and withttand mine
attacks. After a quick competition, they chose the M-ATV from Oshkosh
Defense. Here's a look at its capabilites and design.
Get a grip: Replacing suction cups with
Moving large parts such as windshields and car hoods can be
difficult. But if they're oily and moving fast, the problem becomes even
more challenging. One solution might be friction cups, sort of like
suction cups on steroids that exert much more gripping force.
line of RING-flex® couplings are available in single or double and
close-coupled flexing designs for torques up to 500,000 lb-ft and shafts
up to 11" in diameter. Completely maintenance free and no lubrication
required, these long-lasting, torsionally rigid disc couplings operate
without wear in high temperature environments.
RING-flex® couplings are available in four, six, and eight-bolt
designs to accommodate a wide variety of connections in the
transmissions of pumps, conveyors, printing presses, fans and
generators, or anywhere else a backlash-free connection is required.
Unique designs are available including: flange-mounted, close-coupled,
fail-safe, high-speed, and extra-long couplings.
Hoopster retaining rings fit into much shallower grooves than
regular snap rings or retaining rings making them suitable for light to
heavy loads and ideal for thin-wall tubes. Advantages of the rings
include low-profile, precision circularity, small radial size, and the
potential for high thrust capacity. The low radial profile will not
twist or deform under load as with conventional retaining rings.
The rings come in carbon and 302 stainless steel in sizes from 3/8 to 3
in. and are easily installed without special tools is available at www.smalley.com/hoopster.

Engineers saw and heard great educational content at the Energy
Efficiency Web Conference and Expo. If you missed the live virtual
event, don’t despair! An archive of the full day’s agenda is now
The Energy Efficiency Web Conference & Expo
Design engineers are required to integrate energy efficiency into their
designs while maintaining lower costs, the highest reliability or both.
The editors of Machine Design understand these challenges
and have developed this conference to help engineers understand the
recently imposed energy mandates. The information presented at this
educational event will help engineers compare the different technologies
and product related to energy efficiency. Attendees will gain access to
the technical information needed to help them make the best decisions
without having to travel or take time away from current projects.

Optimizing Mechatronic Systems Using Simulation
Sponsored by The MathWorks
DATE: September 10th, 2009
TIME: 2:00pm ET/11am PT
Are you encountering integration errors in mechatronic systems late in
development during hardware prototyping?
systems in one environment that combines mechanical, electrical, and
control system modeling makes it easier to find performance errors early
in your development process. In addition, current simulation technology
allows integration of engineering data from different CAE tools, such as
CAD and EDA, reducing translation errors.
Attend this live webcast and learn how simulation can help you:
