Dynamic simulation of hydrostatic propel systems
CAE takes an active role in Sauer-Danfoss Propel Division and dynamic simulation is one key factor. Its appropriate usage allows to realize reduced development time and costs as well as a quality benefit for the customer. In the beginning section of the paper, the general simulation approach strategy is described, and then one application of dynamic simulation is introduced. The detailed discussed simulation topic is about the torque pulsation problem in a bootstrap test setup. Pump and motor in a bootstrap test rig are mechanically and hydraulically connected together, hereby driven together by a prime mover, what leads to the same shaft rotation for both units. This setup is normally used in case the engine is not able to provide sufficient power, which applies often in case large closed circuit units are used. Depending on the index position of the rotating kits and the length of the system hoses, the pressure and torque pulsation is influenced dramatically. It is found that pressure/torque amplitude will decrease with tube length rising and the best index angle for the smallest torque amplitude is proposed.
