A hydraulic motor performance testing platform for load control through a dynamometer was developed.The dynamometer received control signals from an industrial computer to adjust the generators internal current,thus regulating the hydraulic motor load.A hydraulic motor with a maximum pressure of 22.5 MPa was chosen as the evaluation subject.Based on the principles of hydraulic transmission and control technology,the hydraulic system circuit design for the experimental platform was accomplished.The feasibility of the design was assessed using AMESim simulation software.Subsequently,the hydraulic motor experimental platform was established and reliability tests were conducted.The experimental findings demonstrate that the results and trends align with the reference data provided by the manufacturer.As a result,the hydraulic system aligns with the experimental design specifications,and the experimental platform adequately satisfies the performance testing requisites for this motor series under diverse operational conditions.
