We offer engineering services based on the study of dynamical systems. Besides measurments, we simulate virtual prototypes behaviour long before physical prototypes had been build. We especially focus on a high modeling depth in nonlinear system components such as fluid, roller and magnetic bearings or unilateral contact. The holistic transient simulation of dynamic systems, also considering tribological components, forms our core competence. “Tribology meets Dynamics” is therefore our motto. We answer your questions relating to
- vibration displacement amplitudes,
- foundation forces,
- minimal film gap,
- friction and oil consumption or
- parameter studies.
For this purpose, we develop, use, and maintain the simulation software EMD. By acquiring a license it can be used in your company, too. In close cooperation with our customers we adapt the modules to meet individual requirements or create new features.
