Multi-Condition Digital Twin Calibration for Axial Piston Pumps : Compound Fault Simulation

ArXi:2603.00199v2 Announce Type: replace-cross Axial piston pumps are indispensable power sources in high-stakes fluid power systems, including aerospace, marine, and heavy machinery applications. Their operational reliability is frequently compromised by compound faults that simultaneously affect multiple friction pairs. Conventional data-driven diagnosis methods suffer from severe data scarcity for compound faults and poor generalization across varying operating conditions.
