Flexible Simulation Software for Hydraulic Drive Systems based on the Finite Element Method (FEM)

Modern hydrostatic drives are mechatronical systems where mechanical, fluid flow, electronical, electrical, and control processes are interacting in a dynamical way. Among these, fluid flow is the most complicated process unless wave propagation or convection dominated effects are neglectible. Using commercial software for computational fluid dynamics hardly permits to include the other processes and suffers from extreme computational effort. The computer code under work should be designed for easy incorporation of the diverse mechatronical components and for time efficient simulation of flow processes in hydraulic components by problem- and component specific Ritz ansatz-functions.
