Noise, vibration and structural dynamics

Competence

Our competence is based on a deep understanding of dynamic phenomena, including sound, vibration, and structural changes. We are especially strong in the multidisciplinary modelling of machines, and we use a large variety of industry-standard modelling tools. With advanced modelling we create virtual prototypes for our customers.

We have top-notch experimentation, development and measurement facilities. We have state-of-the-art measurement equipment for field and laboratory measurements. We can verify simulations and virtual prototypes, and measure the noise, vibration and other dynamic properties of machines and systems.

Solutions

We are specialised in developing solutions for industrial machinery, land and marine vehicles. Typical solutions are based on structural modifications, use of dedicated damping solutions, and active or semi-active vibration and noise control. We expect adaptive control to be a feasible solution for many future applications.

Benefits

By taking the issues of noise, vibration, and structural dynamics into account early in the product development cycle the product will be optimized in a cost-effective way. We offer noise and vibration control and structural analysis services extensively throughout a product’s life-cycle. We help our customers starting from the innovation of new product concepts to development of final products as well as troubleshooting.

• In Yritys-Hamara project noise and vibration solutions with advanced epoxy damping materials were developed. Materials are now used in diesel engines, gantry cranes, mining and drilling equipment, paper machines, and piling equipment. Even 10 dB lower noise levels can be achieved.
