Abstract

The scope of this study is to identify and modify the design parameters of the variable displacement axial piston pump in order to reduce its sensitivity to cavitation when operated in a hydraulic system with pre-established characteristics. An exhaustive analysis of existing theory explaining the cavitation phenomenon is performed and a new approach using the relationship between matter and energy is provided to complete and simplify the description of cavitation. A detailed mathematical model of the axial piston pump is created in order to evaluate the contribution of the pump's geometrical characteristics to cavitation. This model is validated using results from tests performed on two test units. Based on this, an evaluation method of the pump cavitation at the design stage is established and design recommendations are provided.
