The manufacturing version of Indiana Jones is much more interested in lithium, cobalt, and nickel than arks, grails or “Dials of Destiny.” So much so that the current administration is doing its part to keep up with China in the dramatic supply chain cold war taking place across the globe. We’ve all read and reread the headlines, electrification is imminent for our carbon-neutral future—the path toward electrification, however, is quite complicated.
The transition to EVs will lower transport emissions, and adoption can be accelerated by increasing their efficiency. EVs that take advantage of aluminum components can travel further per charge, helping to overcome range anxiety. Automotive manufacturers who select machining tools optimized for aluminum will be able to produce high-quality aluminum EV components ― helping to support the shift to greener travel.
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).
Gleason's special online event from April 26-28, 2022 is all about design, manufacturing and inspection of e-drive gears. KISSsoft will look at several aspects of gear design in an EV system environment.
With the ongoing push towards electric vehicles (EVs), there is likely to be increasing focus on the noise impact of the gearing required for the transmission of power from the (high-speed) electric motor to the road. Understanding automotive noise,
vibration and harshness (NVH) and methodologies for total in-vehicle noise presupposes relatively large, internal combustion (IC) contributions, compared to gear noise. Further, it may be advantageous to run the electric motors at significantly higher rotational speed than conventional automotive IC engines, sending geartrains into yet higher speed ranges. Thus the move to EV or hybrid electric vehicles (HEVs) places greater or different demands on geartrain noise. This work combines both a traditional NVH approach (in-vehicle and rig noise, waterfall plots, Campbell diagrams and Fourier analysis) - with highly detailed transmission error measurement and simulation of the complete drivetrain - to fully understand noise sources
within an EV hub drive. A detailed methodology is presented, combining both a full series of tests and advanced simulation to troubleshoot and optimize an EV hub drive for noise reduction.
