Multi-path high-accuracy hydraulic loading/unloading servo control system suitable for model test

The invention discloses a multi-path high-accuracy hydraulic loading/unloading servo control system suitable for a model test, comprising a hydraulic station, a loading/unloading control system, a main oil path and at least one auxiliary oil path, wherein the hydraulic station is connected with the main oil path; the main oil path is connected with each auxiliary oil path via a connecting pipeline; each auxiliary oil path is connected with a flow division valve and a double-acting oil cylinder; the loading/unloading control system is connected with the control hydraulic station, the main oil path and each auxiliary oil path respectively; and the loading/unloading control system performs high-accuracy hydraulic loading/unloading servo control on the hydraulic station, the main oil path and each auxiliary oil path by operating computer software. The system uses a design of modularized auxiliary oil paths, the main oil path controls the pressure by using an electrohydraulic proportional overflow valve, and each auxiliary oil path realizes connection and disconnection with the main oil path, as well as the set pressure thereof by using a controllable electromagnetic check valve and a three-position four-way electromagnetic valve, thus realizing computer servo intelligent high-accuracy control for the loading and unloading of the model test.
