Bombardier uses VA One, vibro-acoustics simulation software, to simulate structure-borne noise transmission in trains

Vibro-Acoustics

Hybrid FE-SEA analysis is a real leap forward when it comes to acoustical modeling technologies and is likely to set the standard for industrial computational acoustics of large structures for the future. The innovative integration of FE and SEA methods within one model allows the user to solve problems that cannot be addressed by applying SEA or FE methods separately.
