It is essential to adapt the frequently changing hydraulic conditions of the rack, and to understand the cleaning pressure required during the operating state inside each rack. The cleaning pressure results from the intersection point of the hydraulic resistance curve of the rack and the characteristic of the circulating pump.

For this engineering challenge, Miele uses Simcenter Amesim™ software, a mechatronic system simulation solution part of the Simcenter portfolio from Siemens Digital Industries Software. This solution helps Miele engineers simulate the operational characteristics of new products early in the design stage, revealing ways to improve functionality while reducing the need for physical prototypes. “Using Simcenter Amesim enables us to model the racks as super components, with the circulating pump operating as a characteristic and the washing machine itself as a system boundary,” says Malec. “Thanks to the system simulation, we can evaluate future operating points by changing the geometries of the cleaning nozzle or the water lines.”
