Simulation of Transient Seal Friction in Pneumatic Components

Friction in pneumatic components has a significant influence on system behaviour. In the project, a simulation model for the calculation of transient seal friction in pneumatic components is being further developed by the example of a pneumatic valve. The project is being carried out in cooperation with ifas of RWTH Aachen University. At the IMA of the University of Stuttgart, a detailed experimental investigation of the sealing contact is being carried out to ensure an advanced understanding of the system and to enable the validation of the simulation model. For this purpose, lubricants and contact surfaces are characterised, a test set-up is developed and measurements of the seal friction are carried out to validate the simulation model.
