摘      要：The power density of axial piston pumps can benefit greatly from increased rotational ***,the maximum rotational speed of axial piston machines is limited by the cavitation phenomenon for a given volumetric *** paper presents a scaling law derived from an analytical cavitation model to estimate the speed limitations for the same series of axial piston *** cavitation model is experimentally verified using a high-speed axial piston pump,and the scaling law is validated with open specification data in product *** show that the speed limitation is approximately proportional to the square root of the inlet pressure and inversely proportional to the cube root of volumetric ***,a characteristic constant is defined based on the presented scaling *** constant can represent the comprehensive capacity of axial piston pumps free from cavitation.
