Formula 1 Unveils Championship Contending Race Cars

Throughout this week, Formula 1 began unveiling its championship contending race cars with innovators such as Ferrari, Renault, Mercedes, and McLaren. In automobile racing, winning is inextricably linked in some fashion to speed – the speed of the vehicle, but even more importantly, the speed of technology deployment. Technology that delivers a rapid, first-time-right design. Unified in a perpetual …

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 …

Adams Car Integration with Simulation Process and Data Management (SPDM)

To avoid iterative tests and multiple design changes to physical prototypes, engineers today use simulation software. Adams Car is a system dynamics solution that allows car manufacturers to build and test functional virtual prototypes of the complete vehicle under various road conditions and design changes. Adams Car’s architecture is based on databases of CDBs, which …

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 …
