Finding the Solution to a Noise Problem

Product Marketing — Fri, 13 May 2016 17:10:55 +0000

A nighttime noise complaint was issued from the residential area near one of Wärtsiläs main large 4-stroke medium speed engine factories located in downtown Vaasa. The facility produces about 500 engines per year and every engine is subjected to a test run. An investigation found that the likely source of the intolerable noise was from the exhaust from an engine 1000 hour endurance test. Although they discovered the source of the noise, they were unable to solve the noise problem completely.

Multibody Dynamics – Acoustics Integration

Product Marketing — Thu, 12 May 2016 17:02:29 +0000

Even though multibody dynamics and structural dynamics are strongly coupled, acoustic radiation usually must be done in a different environment and the data must be converted to it. While converting the data by itself consumes time and requires manual work, engineers that deal with design production are usually not acoustic specialists. Hence, manual data transfer ...
