Manufacturing an internal combustion engine from extruded aluminum alloy rather than conventional casting offers many benefits, including big size and cost savings. So says Power Beat International Ltd., a research and development company based in Hamilton, New Zealand. Powerbeat's ALU-X(TM) engine employs interlocking sectioned extruded profiles to form the engine block. Replacing one-piece cast blocks, the company claims, allows engines of different capacities, cylinder numbers, and stroke lengths to be made from the same parts. Engine assembly is quick and easy: Tie bolts hold stressed components in compression, eliminating the need for load bearing threaded holes within the block; tee slots incorporated into the extrusion profile allow simple attachment of auxiliary components. Other benefits include superior grain structure for accurate bores and finishes; lower capital costs, higher production capacity; high power-to-weight ratio. Power Beat International is currently developing 200-cc versions of the ALU-X to suit the small engine market. Contact Evan Bydder at firstname.lastname@example.org or call +64-7-843-0011.
Some humanoid walking robots are also good at running, balancing, and coordinated movements in group settings. Several of our sports robots have won regional or worldwide acclaim in the RoboCup soccer World Cup, or FIRST Robotics competitions. Others include the world's first hockey-playing robot and a trash-talking Scrabble player.
A recent example of a major CAE revamp is MSC Apex, released last month by MSC Software Corp. In a discussion with Design News, MSC executives noted that its next-generation platform is designed to substantially reduce CAE modeling and process time, “in some cases from weeks down to hours.”
The Thames Deckway would run for eight miles close to the river’s edge, rising and falling slightly with the tidal cycle. It will generate its own energy from a series of devices that will line the pathway and use a combination of sources to make the path self-sustaining.
