Abstract

The invention relates to a hydraulic system for recycling elastic potential energy generated by deformation of test pieces. The hydraulic system comprises a first energy accumulator, a first reversing valve, a hydraulic cylinder, a second reversing valve, a second energy accumulator, a hydraulic motor and a first hydraulic pump, wherein the first energy accumulator, the first reversing valve and the hydraulic cylinder are sequentially communicated through oil pipes; the hydraulic cylinder, the second reversing valve, the second energy accumulator, the hydraulic motor and the first hydraulic pump are sequentially communicated through oil pipes; and the first hydraulic pump is communicated with the first energy accumulator through an oil pipe. Compared with the prior art, the hydraulic system is simple in structure, high in work efficiency and capable of recycling energy and effectively reducing the experimental cost.

Description

technical field [0001] The invention relates to the field of hydraulic technology, in particular to a hydraulic system for recovering and utilizing the deformation elastic potential energy of a test piece. Background technique [0002] Hydraulic drive is widely used in durability fatigue test of mechanical test piece, which is characterized by large driving force, high vibration frequency and high reliability. Symmetrical vibration test at zero crossing point can be tested in resonance mode. If it is an asymmetrical vibration test, or The vibration test on the side of zero point cannot be tested by resonance. The energy consumption of the test is very large and the cost is very high, which needs to be solved urgently. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a hydraulic system with simple structure, high working efficiency, energy recovery and utilization, which can effectively reduce the test cost and rec...
