This case study explores how MAHLE leverages Siemens Digital Industries Software’s Simcenter portfolio—Simcenter SCADAS XS, Testlab Neo, and Anovis—to revolutionize noise, vibration, and harshness (NVH) testing and analysis in e-bike drivetrain development. Facing challenges of minimizing drivetrain noise, ensuring product quality, and accelerating testing cycles, MAHLE adopted an integrated hardware-software solution within the Siemens Xcelerator platform. This approach enabled an 80% reduction in drivetrain characterization time, enhanced subjective noise assessment beyond decibel measurement, and improved durability through targeted design refinements. Collaborative efforts with Siemens engineers and plans to incorporate simulation and AI-driven analytics position MAHLE as a leader in e-bike innovation and quality assurance.

  • Efficient NVH Testing: Simcenter SCADAS XS and Testlab Neo automate data capture and analysis, reducing drivetrain testing time from five hours to one hour.
  • Subjective Noise Insight: Advanced metrics such as loudness, articulation index, and roughness help MAHLE evaluate noise perception, enhancing rider comfort beyond simple decibel levels.
  • Comprehensive Noise Analysis: Integrated airborne and structure-borne noise assessment captures complex drivetrain and frame interactions, guiding design improvements for noise reduction and durability.
  • End-of-Line Quality Control: Simcenter Anovis enables precise pass/fail criteria based on NVH signatures, ensuring only high-quality units reach production.
  • Strong Siemens Partnership: Hands-on training and ongoing support from Siemens facilitate seamless integration and maximize the value of Simcenter tools.
  • Future Innovation: MAHLE aims to integrate simulation for virtual noise prediction and AI for data-driven insights, accelerating development cycles and product refinement.
