Vibroacoustic Noise Analyses

For Silent & Comfortable Structures...

Primary quality criteria while designing and/or producing a product are economy, performance, aesthetic, safety, maintenance, respect to environment and functionality. Corporations are gaining knowledge and experience on the product designs that fulfill these requirements thanks to rapid development in software and computer technologies. Therefore products that come out of successfull designs satisfy the needs of the customers. In the meantime it is well known that every satisfied need causes another to occur. Lately a new requirement has been added to the list of above mentioned criteria: comfort and especially vibration & noise comfort…

Vibration and noise control has been one of major concerns for different products from different sectors such as automobile, ship, yacht, naval vessel, aircraft, helicopter, washing machine, rocket, sattelite, etc. Consequently it is possible to use analysis and solution methods for vibration and noise in different sectors like shipbuilding, defence, automotive, domestic appliances, transportation, aviation, construction, etc. in order to achieve different goals. To inspect the vibration and noise effects of the automobile engine in the passenger cabin, to determine of sound level during a launching of a missile, to calculate the vibration levels of a domestic appliance, to detect how a building is affected due to forces created as a result of an earthquake, to specify the underwater sound wake of a warship or a submarine, such kind of analyses are very useful.

In MESH, we provide advanced engineering services based on vibration and noise analysis with Statistical Energy Analysis (SEA) Method and Finite Element Analysis (FEA) Method in every frequencies (low, mid, high) by combining the abilities of special software applications and experiences obtained in different projects. For acoustic observations of complicated structures the interaction of airborne noises and structure-borne noises that include the structure's vibration characteristics are considered. Results of the analysis are evaluated and corrective actions are suggested in order to reduce the level of vibration and noise depending on the customer needs. It becomes an easier task to for example obtain a more comfortable automobile/yacht, more safe and stealthy warship, more economical vehicle (by using optimum amount of material such as insulation) and if necessary meet the requirements of national/international rules and regulations.

In this context in MESH, we present the following engineering services of wide scope;
