While engine noise disappears in electric vehicles, noise from motors, inverters, gears, and body structures becomes more prominent, requiring NVH design that differs from conventional approaches.
This seminar organizes EV noise generation mechanisms from electromagnetic, mechanical, and aerodynamic perspectives and clarifies the relationship between frequency characteristics and design parameters.
Furthermore, it systematically explains early-stage noise prediction methods, appropriate use of CAE, and practical low-noise design approaches.
Including common failure cases in real-world practice, the seminar structures a reproducible design framework.
Do you have these challenges?
- Cannot identify causes of noise complaints after EV transition
- No issue in motor alone, but noise worsens at vehicle level
- CAE results do not match actual noise
- Countermeasures for high-frequency and harsh noise are not systematized
- Many post-design fixes increasing cost
Target participants
- Engineers involved in NVH design of EV/electric powertrains
- Development engineers for motors, inverters, gears
- CAE engineers for vehicle vibration/noise evaluation
- Practical designers for prototype evaluation and feedback
- Design managers treating quietness as competitive performance
Seminar Overview
This seminar aims to treat NVH issues specific to electric vehicles not as “phenomena to be understood” but as “design variables,” systematically organizing everything from noise generation mechanisms to early-stage design countermeasures. Since EV noise sources are complex and differ from conventional engine vehicles, building a reproducible design process is essential.
・ Systematic organization of EV noise structure (electromagnetic, mechanical, aerodynamic)
・ Relationship between frequency characteristics and design parameters
・ Noise prediction approaches in early design stages
・ Proper use of CAE and simplified models
・ Practical framework for low-noise design
