Hydraulic motor constant low speed characteristics measurement study

Abstract Due to the special characteristics of hydraulic motors, the minimum stability characteristics are often one of the important characteristics to be considered in hydraulic system applications. In this paper, based on the analysis of the hydraulic mathematical model of the axial piston hydraulic motor, the model of the axial piston motor is established by using AMESim simulation software, and its low-speed characteristic curve is output through simulation to verify the validity and reasonableness of the low-speed characteristic testing scheme of the hydraulic motor. Finally, a hydraulic motor constant low speed characteristic test system is built based on LabVIEW software, and a field verification test of the hydraulic motor constant low speed characteristic is carried out, which provides some engineering reference value for the hydraulic motor constant low speed characteristic test.
