Structural Dynamics Integrity & Vibro-Acoustics Simulation for Marine & Shipbuilding Industry: CFD, FEA, SEA & BEM
FEA & CFD Based Simulation Design Analysis Virtual prototyping MultiObjective Optimization
Structural-borne noise and vibration need to be minimized for passenger comfort and reduced environmental impact. Our full suite of vibro-acoustics simulation, and optimization tools ensures that we can minimize the structural dynamic impact of your vessel and its components early in the design phase. From large cruise ships to yachts, from frigates to submarines, many design challenges shall be addressed in the design phases of marine applications. If on the one hand the exterior noise, due to propellers, hull radiation or muffler, has to be limited for discretion or environmental reasons; on the other hand, interior noise is of concern for crew and passengers' comfort.
