Klingelnberg examines gear noise behavior and the evolution of the electric powertrain. 

When it comes to noise, vibration and harshness (NVH), I’m reminded of that dog-van scene from Dumb and Dumber where Jim Carrey says, “Want to hear the most annoying sound in the world?” and then proceeds to emit an astonishingly awful noise. Annoying as NVH may be, it’s a key metric in drive-system development for e-mobility, and the careful design and manufacture of gears are crucial to minimizing NVH as tolerance variations can result in large differences between nominally identical components.

Hexagon’s Manufacturing Intelligence has released a comprehensive report entitled "Recharging the Automotive Market." The body of work was produced by Hexagon and draws from the original research conducted with Wards Intelligence and Informa Tech Automotive Group (ITAG).

Virtual prototyping (VP) is an area where huge advances have been made. As gear and transmission systems, and the methods of their production, become more complex and more interdependent, finding ways to use VP across the entire development process—from the initial design, through analysis, right up to manufacturing—ultimately means gaining a better understanding of system performance and efficiency.
