PWC-200L (200kN)
Computer Control Electro-hydraulic Servo Double Channel Axle Fatigue Testing Machine
Main functions
The computer control electro-hydraulic servo double channel axle fatigue testing machine is designed according to the user's test requirements. It is mainly composed of two servo linear actuators, a set of constant pressure servo pump station, a set of multi-channel hydraulic oil filter and energy storage module (oil separator for short), servo controller, test software, pipelines and accessories.
The computer control electro-hydraulic servo double channel axle fatigue testing machine is mainly controlled by the test force and displacement closed-loop, and the fatigue test of the vehicle axle assembly is completed by two loading control points.
