Helicopter hydraulic energy simulation testing platform

Abstract

The embodiment of the invention relates to the technical field of testing, in particular to a helicopter hydraulic energy simulation testing platform, which adopts a semi-physical simulation method to carry out simulation testing on hydraulic energy, and a hydraulic energy system constructs equivalent loads for a real object and a hydraulic user system. Load flow and pressure of the hydraulic subsystem during execution of an action task are simulated, an execution component and a control strategy of the action task are replaced by a simulation model, the simulation model and a simulation load are organically combined to form a real-time simulation closed-loop system, test research on a helicopter hydraulic energy system is realized, peripheral working conditions of a helicopter hydraulic energy system which cannot be built in a laboratory are simulated by using a simulation model, so that the problems of low full-digital simulation confidence coefficient, incapability of meeting the development requirements of light weight, intelligence, high maintainability and high reliability of helicopter hydraulic energy, complete physical verification test, high test cost and long test period, and an optimization iteration test is inconvenient to carry out are solved.
