The New Year’s Ball Drop wouldn’t be possible without a sophisticated electromechanical system that must operate reliably during the most critical 60 seconds of the year.
April 6, 2023
More than a billion people around the world unite to ring in the New Year, their eyes set upon the glittering New Year’s Ball in Manhattan. Thousands are gathered at Times Square — the famed “Bow Tie” of Midtown — braving the December cold and peering through glasses with numerically shaped frames. Millions more tune in from their various screens at home. With so much riding on its descent, the Ball, along with the mechanical and electrical systems responsible for its operation, must operate like clockwork.
Difficult general conditions, rapidly rising food and fuel prices, as well as the ongoing coronavirus pandemic and related regional lockdowns weighed on economic development and slowed economic growth in the past business year. Nevertheless, Liebherr’s total revenue increased significantly compared to the previous year. The group achieved increased revenue in 10 of its 13 product segments, some of them significant. It thus surpassed its previous record from 2021 by €950 million.
At Interpack in Dusseldorf, the drive specialist Nord Drivesystems will present its wide product portfolio and great expertise in the packaging industry from May 4-10, 2023 – from decentralized frequency inverters to energy-efficient drives to high-performance surface treatments for washdown or spray areas.
Bonfiglioli S.p.A, global leader in the market of drives for industrial automation, wind generators and mobile machinery in the construction, earthmoving and intralogistics sectors, following the communication released on February 7, 2023, is proud to announce that it completed the 100% acquisition of the share capital of Selcom Group.
The American Gear Manufacturers Association (AGMA) has changed its board of directors. These changes took place at the 2023 AGMA Annual Meeting in Lake Buena Vista, Fla.
Sumitomo Drive Technologies and Lafert Group will be jointly exhibiting a new version of their drive for applications in automated guided vehicle (AGV) systems at Logimat 2023 from April 25 to 27 in Stuttgart, Germany (Booth F45, Hall 6). The Smartris Drive Compact is a compact drive that is just a quarter of the size of the standard model.
This study presents a simulation method for considering complex wheel bodies in an analytical tooth contact model. The wheel body is considered using reduced FE stiffness. Reduction points are defined over the width and linked with the analytical gear.
For cylindrical wheel bodies, comparative calculations show fewer deviations from the expected results with the new method. This is due to the additional degrees of freedom in the FEM model. In the calculation with cylindrical wheel bodies, bending due to axial force in tooth contact could also be verified in addition to the deformation in tooth contact and the influence of the shaft-bearing system.
There is an increasing trend toward integrating evermore compact smart components into larger, more complex motion control systems, and advances in AI, ML, and IIoT are helping with the speed and quality of their adoption.
After five jam-packed days of innovative product launches and major company announcements, enlightening education sessions and countless networking opportunities, CONEXPO-CON/AGG & IFPE 2023 have come to a close, but not before taking the construction industry to the next level.
