Case Study: Hyundai Motor Company reduces APAS design optimization time by 50% with Hexagon Actran

Actran helps reduce time to optimize design of active pedestrianalerting system by 50%

Hyundai Motor Company, a leading global automotive manufacturer, faced the challenge of designing an efficient Active Pedestrian Alerting System (APAS) for its electric vehicles. To meet new safety regulations without causing noise pollution or reducing passenger comfort, engineers needed to optimize the system's speaker design, a process that traditionally required time-consuming physical prototyping. To address this, they turned to Hexagon and utilized their MSC Actran software for advanced acoustic simulation.

By implementing Hexagon's Actran solution, Hyundai engineers were able to create detailed finite element models to analyze and optimize the speaker's performance virtually. This allowed them to run parametric studies and perfect the design for optimal sound frequency and speaker placement. The use of Hexagon's technology reduced the time required to optimize the design by 50% compared to traditional methods. The resulting APAS design successfully met all regulatory requirements, provided excellent sound focusing performance, and was confirmed by subsequent physical testing.
