Abstract: In light of the characteristics of the swash-plate axial piston pump with multiple failure modes, first, the Failure Modes, Effects and Criticality Analysis (FMEA) method is employed to identify the failure mode and effect of each component in a piston pump. Then, on the basis of the analysis of the stress factors that impact the failure rate, a simplified failure rate model of the swash-plate axial piston pump was set up according to the two forms of stresses applied in the Accelerated Life Test (ALT). Finally, an accelerated model of the swash-plate axial piston pump was obtained.

Key words: turn and control of fluid, swash-plate axial piston pump, accelerated life test(ALT), failure rate, accelerated model
