The recent EUROTRANS General Assembly in Bad Homburg, Germany, on November 29, 2024, was highly productive, bringing together participants from 10 countries. The association extends heartfelt thanks to host Mr. Fabian Maurer, Ringspann GmbH, Bad Homburg, and his team for their hospitality.

Tooth contact analysis is an integral part of the gear design process. With the help of these simulation tools, it is possible to calculate the excitation caused by a tooth contact (Ref. 1). Usually, the load-free transmission error or the total transmission error under load is used for this purpose. However, the calculation with the tooth contact analysis ZAKO3D allows only a quasi-static consideration of the excitation. To better evaluate the behavior in the overall system, it is therefore necessary to perform a dynamics simulation. However, the main disadvantage of such dynamics simulations is the much longer computing time compared to quasi-static tooth contact analyses due to the high computational effort.

As publishers, we’re constantly reevaluating our brand and our identity. We want our connection with you to remain close and fresh, so that when you see our publication, your reaction is, “Oh, yeah. These are my people. They speak my language.”

Of course, much of that reaction is derived from the content. But some of it is also from the design and how the content is presented. Over time, designs become stale. Fonts, color schemes and visual effects that were once popular become as outdated as bell-bottom pants. (Wait, never mind. I think those are back in style again. Anyway, you get my point.)
