NYCU (National Yang Ming Chia Tung University) Vulpes Racing—founded in 2008—is a Formula Student Team that combines mechanical engineering, industrial design, public relations, video production and marketing expertise. 

Siemens Digital Industries Software and Daimler Truck AG recently announced a new collaboration to implement a state-of-the-art digital engineering platform built using the Siemens Xcelerator portfolio of software and services. The new platform will enable Daimler Truck to explore a future of commercial vehicle innovation and the efficient product development and lifecycle management of trucks and buses and will be rolled out globally across Daimler Trucks’ engineering hubs, brands and business segments.

The new KISSsoft release 2023 comes with numerous novelties. Among others, Gear Mesh Frequencies (GMF) can now be calculated for cylindrical and bevel gears. GMF results are visualized in two different diagrams, i.e. GMF versus rotational frequency of the reference gear, and GMF versus amplitude.

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.

I think I spend more time talking about ball bearings today than at any other time in my career. Ball bearings have always had a large place in automotive, but not typically in high demand positions—other than a few niche areas. High demand positions, such as axles and planetaries, were typically reserved for tapers, needles and cylindricals. The landscape is changing quickly.

EV developers are finding a competitive edge through efficiency gains not only in new battery pack technology and electronic components, but also through new developments in electric machines.  

Siemens Digital Industries Software announced that the latest release of Simcenter software for mechanical simulation helps streamline electrification engineering projects, assists new aircraft meet margins of safety, simplifies durability testing across many industries and much more.

Hexagon’s Manufacturing Intelligence division recently introduced Elements, new simulation software that helps engineering teams understand the behavior of systems that are becoming increasingly complex in modern products. Using the software, teams can evaluate the performance and feasibility of new design concepts quickly to inform more efficient product development and reduce risk and cost.

Next-generation technology—everything from the electrification of vehicles to e-motors, bearings, mechatronics, and thermal management—was discussed during the Schaeffler Symposium 2022 in Detroit. I sat down with Jitesh Modi, director of engineering, during the event to discuss the “reinvention” of bearings for EV applications.
