Noise and Vibration

Structural vibration can be a source for many product related problems; it can cause fatigue and durability problems to the product itself, and it can cause adverse reactions to the user or bystanders in the form of undesirable vibrations that can be felt or heard. As well, undesired structural vibrations can prevent products from operating as required and potentially becoming a safety concern. Often referred to as NVH (Noise, Vibration, and Harshness) or N&V (Noise and Vibration), this problem is one of the most often directly perceived quality traits of a product, and is therefore one of the most sought after targets for performance by the product development team to help differentiate themselves from competition.

Noise & Vibration Applications

Compumod offers leading CAE solutions to help customers understand and address product NVH issues with virtual prototypes, helping to reduce product developments costs, accelerate time to market, and optimize noise and vibration performance. With leading FE (finite element) and MBD (multi body dynamics) capabilities from MSC, users can simulate and predict how a component or system will vibrate under varying operating conditions; for example how a driver or passenger of a car driving down the road can perceive the engine sound at cruising speed or under acceleration and at the same time perceive the feel and the noise generated as the car runs over a pot hole. Engineers in almost every industry use Compumod applications to improve performance, reduce weight and reduce costs. Based on over 40 years of experience in solving industrial problems, MSC has developed some of the most efficient and accurate solver techniques and methods that have been implemented to help solve the largest and most complex systems NVH problems encountered.

Capabilities include:

  • Structural Vibrations

  • FRF Based NVH Analysis

  • Internal and External Acoustics

  • Large Model and Assembly Simulation
