Noise, Vibrations & Dynamics

 Noise, Vibrations & Dynamics

Rattle, whine, torsional vibration, rotor dynamics, and other noise and vibration issues are common in rotating machinery like pumps, motors and compressors. Too much vibration can lead to excessive noise levels that exceed regulations or can lead to poor performance and reliability. Meeting these performance requirements and regulations can be a challenge if you don’t truly understand the performance of your machine and the source of the noise and vibration.

Siemens PLM Software offers a comprehensive set of advanced vibration and acoustic simulation and testing solutions that can help you predict the dynamic and acoustic performance of your machine earlier in the development process, as well as determine the source and transfer path of noise in machines that are already in the field.

Noise and vibration are critical performance aspects of machinery. Too much of either can have an impact on the quality of the final products your machines produce. Excessive noise directly impacts the machine operator and reduces overall factory-floor noise levels which can lead to lower productivity from shop floor workers. Uncontrolled vibration can directly limit the quality of the part being produced, causing loss of time and product for your end customers. To deal with noise and vibration problems, machine engineering departments require a very comprehensive set of simulation and testing solutions. These should be capable of handling target setting, product design, refinement, final prototype validation, certification, troubleshooting and more.

Siemens PLM Software simulation and testing solutions can help you spot resonances and noise sources, even the most unexpected ones. Our portfolio of dedicated noise and vibration solutions includes 3D simulation tools that can be used during early machine development to predict machine dynamics, vibration and interior, and exterior acoustics. Additionally, Siemens offers the hardware and noise testing expertise for noise, which can be deployed on physical prototypes as well as for correcting issues with existing machines in the field.
