Actran Helps Reduce Time to Optimize Design of Active Pedestrian Alerting System by 50%

Overview:

At moderate to high speeds, the only external noises typically generated by electric vehicles are caused by wind resistance or tire noise. As a consequence, electric vehicles present a risk to pedestrians and cyclists, especially those who are visually or hearing impaired or listening to headphones.

Hyundai active pedestrian alerting system Regulations have been issued in both the United States and the European Union requiring that newly manufactured electric vehicles make an audible noise when traveling at low speeds. These regulations have differing requirements for the amplitude and frequency content of the warning sound.

Results Validation:

The simulation results were validated by conducting a 1-volt sine sweep test for both the actual speaker and the simulations. As shown in the figure above, the spectral behavior of sound at 1 meter from the speaker predicted by simulation matches the physical measurements nearly perfectly.

By using Actran to optimize cavity and duct resonances, Hyundai engineers were able to design the speaker to handle low, mid and high frequencies as needed to meet both US and EU regulations while at the same time minimizing speaker size and power consumption. “The simulation results provided by Actran were much more comprehensive than information generated by physical testing, which helped Hyundai engineers quickly iterate to an optimized design in about half the time that would have been required using traditional build and test methods,” Lee said.

Simulating SMC part response with greater confidence using Digimat

Overview:

While Sheet Molded Compound (SMC) materials have been widely used in the automotive industry for some time, recently there has been a move to apply SMCs on more structurally demanding components. Though the material has long been considered quasi-isotropic with relative success, it has become apparent in industry that due to the complex manufacturing process, optimal structural design is not possible without considering the real anisotropic nature of the material.. With growing demand from the market, now is the time to leverage advanced SMC modeling capabilities targeting crash performance.

Results Validation:

Static and crash FEA simulations can now attain an excellent level of accuracy in stiffness and can capture peak load and displacement trends for typical part load cases.

The inner seat part illustrates the proposed workflow from process simulation to structural application. The Digimat simulation achieves a much better fit with respect to test data for most load cases, including head impact (puncture) and provide a good indication of hot spot localizations.
