The invention relates to performance testing equipment of hydraulic equipment, in particular to an on-line virtual testing analysis system of the hydraulic equipment. The on-line virtual testing analysis system of an electrohydraulic servo system is established by a computer platform and comprises an acquisition module, a management module, a report module and an analysis module, wherein the acquisition module uses a PXIe acquisition platform, an SCXI signal conditioning platform and a CDAQ portable data acquisition platform to acquire data; the management module comprises a data management subsystem; the report module displays the result in a form of word report aiming at the test result of an object; and the analysis module comprises an analysis subsystem for performing characteristic value acquisition on a waveform result acquired by a data testing part and extracting the required result. The on-line virtual testing analysis system of the electrohydraulic servo system has the functions of modeling analysis, testing method prompt, data acquisition and real-time signal analysis and the like, and improves the detection efficiency.
