Innovation and collaborative, synchronized program management for new programs
Fuel economy measures have a positive effect on the vehicle’s fuel consumption, but inevitably impact other aspects of the vehicle’s performance, such as powertrain related NVH and acoustics.
Our integrated solutions help diagnose, analyze and resolve powertrain NVH issues such as engine vibration and acoustic radiation. Our integrated approach supports powertrain and driveline integration related NVH issues, while balancing with other performance attributes such as fuel economy, drivability and ride comfort, and increasing the efficiency of the NVH development process.

The global demand for more eco-friendly vehicles compels automotive OEMs and suppliers to develop fuel-efficient internal combustion engines. While fuel economy measures positively impact the emission of greenhouse gasses, it inevitably affects the vehicle’s noise, vibration and harshness (NVH) and acoustic behavior. Weight reduction and downsized turbocharged engines might increase torsional excitation causing low frequency driveline NVH issues when integrating the driveline into the vehicle. In addition, new energy management systems such as cylinder deactivation systems and start-stop systems can cause new transient NVH phenomena. These new complex NVH issues need to be addressed on top of the typical engine-related NVH topics, such as; engine radiation, gearbox rattle, whine, judder, clunk, fuel slosh, intake and exhaust noise, and auxiliary noises.
Siemens PLM Software solutions do the trick. By integrating test and simulation techniques with engineering insights, they combine proven and new technologies to address NVH and acoustic issues at all stages of the development. They help manufacturers save time and cost to diagnose, analyze and resolve driveline NVH and drivability issues while balancing fuel economy, drivability, NVH and ride comfort, and increasing the efficiency of the NVH development process.
Explore the key areas of this solution.
Minimize noise and optimize sound quality by simulating interior and exterior acoustic radiation. Perform parametric analysis and design refinement also during the early design stages.
Gain insights into the origin of driveline vibrations by combining linear and nonlinear systems and studying the coupling between mechanical 3D structures or 3D shafts with actuators.
Maximize powertrain testing efficiency by simultaneously acquiring all relevant data to optimally balance NVH against other performance and fuel efficiency criteria.
Evaluate acoustic quality and design the perfect sound. Assess sound and acoustic quality using psychoacoustic metrics such as loudness, sharpness, roughness and fluctuation strength.
Integrate (sub)systems and keep performance. Balance and optimize seemingly-conflicting requirements for NVH, fuel economy and drivability.
