Microgravity Studies on a Pump Package

Microgravity problems are considered here from the standpoint of engineers that are requested to maintain a very low level of self induced vibrations generated by a pump package. The request to conceive a mathematical model for the evaluation of the total dynamic force generated and transmitted from the package to the interfacing structure has induced a lot of activities and studies in this field. Investigations about internal sources of vibration have been made by means of analytical techniques and experimental evaluations. Preliminary results and considerations are presented.
