Noise & Vibration – Simulating Reality, Delivering Certainty

Perform multiphysics CFD simulations that are within 2% of physical experimental results

mscsoftwareblog — Mon, 28 Mar 2022 12:00:33 +0000

To simulate fluids or gasses, you might use CFD. To simulate solids, you might use FEA or MBD. To simulate the real world, such as a wind turbine moving through the air, a pure CFD or a separate pure FEA analysis is sometimes not enough. Instead, a multiphysics simulation, or co-simulation, is necessary to ensure ...

MSC Nastran 2019.0: Improved Accuracy Without Sacrificing Performance Speed

Product Marketing — Wed, 02 Jan 2019 22:31:15 +0000

Join us to learn more about the exciting new capabilities available in MSC Nastran 2019.0, available in January, 2019. With the advances in electric car manufacturing, and quieter electric motor engines, high frequency Noises and Vibrations are becoming more prominent, which makes NVH calculations exponentially more expensive. In this release, we are introducing a new ...

Analysis of IXV Space Hardware Exposed to Acoustic Diffuse Random Field

Product Marketing — Wed, 05 Sep 2018 23:03:28 +0000

Reusable launchers are recognized as one of the solutions to lower launch costs. Contrary to more traditional expendable launchers, the reusable launchers are able to launch a payload and return part of the structure on the Earth surface. In 2015, ESA launched the Intermediate eXperimental Vehicle (IXV). This vehicle was developed by Thales Alenia Space ...

Noise Prediction for Electric Vehicle Powertrain

Product Marketing — Mon, 20 Aug 2018 23:25:52 +0000

NVH (Noise, Vibration, and Harshness) or N&V (Noise and Vibration), is a problem that is often directly tied to the overall quality of a product. Therefore, it is one of the most sought after targets for performance by product development teams to help differentiate themselves from competition. With the emergence of hybrid and electric vehicles, ...

Industry Applications of NEVF with Dr. Neil Bishop

Product Marketing — Wed, 30 Aug 2017 16:27:52 +0000

Dr. Neil Bishop of CAEfatigue Limited, one of the most renowned experts in Fatigue Dynamics and FEA, partnered with the MSC Nastran team to create a more dynamic and integrated solution after experiencing the many limitations of fatigue simulation. Thus, Nastran Embedded Vibration Fatigue (NEVF) was born. NEVF is more accessible, easy-to-use, and flexible in ...

Accurately Predicting the Behavior of Pneumatic Tires

Product Marketing — Thu, 16 Jun 2016 17:00:31 +0000

When developing the sub-systems of a vehicle, compromises have to be made among several contrasting objectives. On one hand, one wants to set all sub-systems - such as suspensions - so that they allow efficient and safe handling of the vehicle. On the other hand, comfort cannot be sacrificed too much. Being the support of the vehicle and providing forces necessary to control it, pneumatic tires are one of the most important components. However, it is very challenging to model them due to both their complicated composition and the materials used in their manufacturing process. On top of that, the modeling is done by suppliers and an in depth understanding of the interaction with the vehicle must be attained.

Simulation Software Helps Optimize the Golf Club Performance

Product Marketing — Thu, 02 Jun 2016 17:00:39 +0000

Cleveland Golf launches new golf club designs on an annual basis in a highly competitive, performance-driven market. With competition gaining groudn on them, Cleveland’s management challenged Jeff Brunski, Performance Research Engineer, to find ways to truly optimize their golf club performance – and that meant evaluating hundreds of design variations.

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.

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 ...
