Virtual End-of-Line Test
Power Transmission Engineering
Within the scope of this work, an EMBS model for the first stage of a two-stage gearbox was built in the Simpack simulation environment. The high-speed demonstrator gearbox of the WZL Gear Research Circle was chosen as the application case.Read More
As EV Sales Stall, Plug-In Hybrids Get a Reboot
IEEE Spectrum
Automakers got one thing right: Electrified cars are the future. What they got wrong was assuming that all of those vehicles would run on battery power alone, with gasoline-electric hybrid technology bound for the technological scrap heap.Read More

108 Years Old Is the New 30
Gear Technology
2024 was a busy year for the gear industry. Large and small companies had to navigate the interest rates, tariffs, supply chain disruptions, labor shortages, and the unknown economic outlook with an election year in the U.S. Leaders that normally would be brainstorming their five-year strategic plans had to get comfortable with a day-to-day strategy. As each quarter ended, however, AGMA witnessed resiliency, innovation, collaboration, and even quite a bit of growth for some sectors—it was an exciting year to visit members in person.Read More
Modeling and Dynamic Analysis of Split Torsion Transmission System Considering Backlash and Center Distance Errors
Scientific Reports
The split torque gear transmission holds significant potential for use in helicopter main reducer transmission systems due to its benefits of low noise, high power-to-weight ratio, and high reliability. In this context, a nonlinear dynamic equation was formulated in the present study for a single-input dual-output gear split-torque transmission system, and the system’s dynamic behavior was examined under the effects of center distance error and backlash using the fourth-order Runge-Kutta method.Read More

Cleveland-Cliffs Partnering with Nucor on Potential Bid for U.S. Steel, Sources Say
CNBC
Cleveland Cliffs is partnering with rival Nucor in a potential bid for U.S. Steel, whose takeover by Japan’s Nippon Steel was blocked by the White House earlier this month, sources tell CNBC’s David Faber. Cleveland-Cliffs would purchase all of U.S. Steel for all cash and then sell off the Big River Steel subsidiary to Nucor, the sources said. U.S. Steel’s headquarters would remain in Pittsburgh under the deal.Read More
New Lithium Reserves Discovered in US, China
Semafor
Lithium deposit discoveries in the US and China could reshape the global race for the mineral, which is vital to the green energy transition. One cache, found along the borders of Nevada and Oregon, potentially holds as much as 40 million metric tons of lithium, while Chinese state media said reserves had been found that upped its share of global lithium supplies from 6% to 16.5%, although details were scant.Read More
OpenAI Has Begun Building Out Its Robotics Team
