Bombardier

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

"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.”

Ulf Orrenius, Senior Specialist: Acoustics and Vibration, Bombardier Transportation

Underground Transportation

Improve Passenger Comfort

Reducing noise and vibrations inside the structure of modern trains to ensure a high level of passenger comfort is no easy task and requires detailed knowledge of transmission paths. Industry leaders are making extensive use of ESI's VA One software to perform the complex vibro-acoustic analysis needed.
