Structural dynamics

Structures excited by time varying loads tend to fail through fatigue if not properly designed, or may lead to noise emissions if not properly damped.

Creo Dynamics are engaged in several projects dealing with vibro-acoustic challenges. We perform finite element analyses to predict sound levels in aircraft or truck cabins, or to predict levels of vibrations for components to be installed in products used in demanding environments. But we also use our simulation tools to design systems for active noise and vibration control, for the aerospace industry as well as for car and truck developers.

We develop our tools further to also include porous materials and its complex damping characteristics. We combine our competence within vibro-acoustic simulations with our experience in experimental structural dynamics to minimize the number of test sequences, in order to reduce cost and lead times. We perform experimental modal characterizations in our lab and import measurement data into our simulation software to validate our simulation models.


Example projects

• Modeling the damping of porous materials
• Prediction of cabin SPL of propeller aircrafts
• Prediciton of levels of exhaust system vibrations
• Studies on novel concepts for semi-active systems for vibration control
• Modeling of systems for active noise and vibration control
