Vibration and Noise of Machines – Simulation-based Development and Troubleshooting

We asked our customers: Reducing unwanted vibrations is often the most relevant aspect for them when developing new products*. No wonder, because if you ensure already in the planning and design phase that vibrations remain controllable during commissioning and ongoing operation, you avoid not only trouble, but also costs resulting from machine downtimes, poor product quality, machine speeds that cannot be achieved, or additionally necessary reduction measures.

Virtual prototype tests can be used to optimize vibration behavior in the early stages of new or further development. With the help of simulation, however, you not only achieve vibration optimization – an improvement in component or machine functionality, the reduction of machine noise or an increase in efficiency can also be (partial) goals. In short: You can develop more efficient and reliable machines in less time.

FE and MBS calculations have a long tradition in our company. For more than 50 years we have been performing numerical simulations for customers from a wide range of industries – in all phases of the machine's life: from product development to production, commissioning and operation, right through to the end of the machine's service life. Depending on your needs, we can take over the entire process or provide support in the event of capacity bottlenecks or technically difficult issues.

How does simulation make the development process more efficient? When should simulation be used? And when does it make sense to outsource it?

Not all machines require a separate machine foundation, but sometimes it is indispensable – especially when there are high demands for quiet running and vibration protection. This is because, in order to prevent the vibrations emanating from the machine from being transferred to the supporting (building) structure, a dynamic design of the existing machine support, i.e. the machine feet, is often not sufficient for larger machines. This particularly applies to machines that generate greater dynamic forces and machines that require precision – such as turbines, compressors, printing machines, presses, hammers, measuring machines and machine tools.

The machine foundation required in these cases must be individually tailored to the operating and boundary conditions of the machine and its surroundings. For the design, specialist competence is necessary in machine dynamics, but in particular also in structural engineering respectively structural dynamics – two of our areas of expertise.
