Actran – Simulating Reality, Delivering Certainty

New Regulations for Electric Vehicles

Product Marketing — Wed, 03 Jul 2019 22:40:51 +0000

This week marked an important EU mandate for electric vehicles, requiring all new electric vehicles to emit a noise at low speeds. Read how Actran is helping OEMs, such as Hyundai, by optimizing APAS system design. At moderate to high speeds, the only external noises typically generated by electric vehicles are caused by wind resistance ...

Formula 1 Unveils Championship Contending Race Cars

Product Marketing — Wed, 21 Feb 2018 20:22:24 +0000

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

Product Marketing — Fri, 20 May 2016 21:00:13 +0000

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)

Product Marketing — Tue, 17 May 2016 17:01:04 +0000

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

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 ...

Room to Room Vibration Tranmission

Product Marketing — Thu, 05 May 2016 22:51:42 +0000

Architects and acoustic consultants struggle to accurately estimate the vibration reduction index for their building designs. ISO 10848 defines a method for measuring this, but it is a long, tedious and expensive process which is implemented by building two rooms and their junctions one by one, exciting the wall and measuring the flanking and direct noise. This process must be done for each building design. When the design changes or the desired results are not achieved, the structure must be demolished and built again from the beginning.

Simulating Brake Squeal Noise

Product Marketing — Wed, 04 May 2016 17:29:52 +0000

Brake squeal is one of the most challenging problems that car manufacturers have today. It occurs as a result of the vibration of the brake components such as brake disc and brake pads and therefore it disturbs the driver and passengers. Furthermore, because of its complex nature it is hard to completely understand the causes ...

Multidisciplinary Solutions For Brake Squeal

Product Marketing — Tue, 03 May 2016 17:48:51 +0000

Although engineers have started to use simulation software to test brake squeal, its complex nature usually requires more than one different software and discipline. This makes it difficult to transfer data from one software to another and to work in different environments. To address complex brake squeal in one environment, multidisciplinary solutions (MD) can be used. ...
