Simulation Accurately Predicts Noise Generated by Automotive Side Mirrors

An acoustic engineer is someone whose job is never done. Acoustic engineers in the automotive industry have achieved tremendous progress in recent years in making vehicle interiors quieter and more comfortable by reducing powertrain and road/tire noise. But as these major noise sources are reduced, other noises that were previously muffled have become much more ...

Weight Reduction of an Engine Mount

Trelleborg is a global automotive supplier that offers sealing, damping, and protection solutions to the automotive industry. To reach their goal of complying with CO2 regulation, Trelleborg uses material modeling and simulation software.   Challenge To comply with CO2 regulations (2015: 130g   2020: 95g) To reduce the average weight of a car by 200 kg ...

Finding the Solution to a Noise Problem

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

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 ...
