Multibody Dynamics & NVH (Noise, vibration, and harshness)
FEA & CFD Based Simulation Design Analysis Virtual prototyping MultiObjective Optimization
Noise, vibration, and harshness (NVH) are critical factors in the performance of many mechanical designs but designing for optimum NVH can be difficult. While strength and durability limits are being pushed further and further, requirements for noise reduction are becoming more stringent. In addition, focus is increasingly being placed on transmission and powertrain noise because other sources could be reduced meanwhile.
Major noise sources in powertrains include clearances in cranktrain bearings, piston liner contacts and contacts in valve trains, timing drives and transmissions. Simulation allows individual mechanical noise sources to be localized and represented very accurately. The elastic multibody dynamics solution with MSC Adams, Simulia Simpack and Ansys Motion connecting FE-based flexible bodies simulation sotware such as Abaqus, Ansys and Nastran including non-linear contact joints, enables the investigation of all noise phenomena of engines and transmissions including gear rattle, gear whine, chain noise and specific phenomena in the driveline.
Multibody dynamics and structural dynamics are strongly coupled, taking into account mass, inertia, contacts and flexible structures. But acoustic radiation is usually handled by a weak coupling that requires new models and conversion of data. Connecting the two worlds on a daily basis may lead to loss of information and requires additional manual work. Mechanical analysts who design the products are rarely acoustic specialists.
By combining MBD and acoustics in an engineering procedure for design and optimization, an efficient solution is created. Enteknograte extremely skilled engineers are experts at utilizing Computer Aided Engineering (CAE) for analyzing fatigue behavior. Our team is highly efficient in applying Adams, Actran, Ansys and Abaqus for solving almost any type of NVH challenges.
