Title:
DYNAMIC AND STATIC COMBINED ELECTROMAGNETIC LOADING HOPKINSON ROCK ROD WAVE PROPAGATION TEST DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/008010
Kind Code:
A1
Abstract:
A dynamic-static combined electromagnetic loading Hopkinson rock rod wave propagation test device, mainly consisting of a loading frame system, a rock rod system, an electromagnetic pulse emission system, an axial pressure servo control loading system, and a data monitoring and acquisition system. The loading frame system mainly consists of a supporting table (1), a connecting rod (4), a rock rod support (6) and axial pressure loading fixed baffles (2, 11), and functions to provide the supporting table (1) and guide the rock rod centering. The rock rod system consists of rock rods (5, 7, 8) having equal diameter, different length and quantity, and identical or different material to meet different test requirements. The electromagnetic pulse emission system mainly consists of an electromagnetic pulse stress wave excitation cavity (3) and a control system thereof. The axial pressure servo control loading system consists of a hydraulic loading cylinder (10), an axial pressure loading piston (9) and an axial pressure servo control system. The function of the axial pressure servo control loading system is to programmatically control the loading, holding and unloading of an oil source system, and can ensure that a static axial pressure is maintained to be relative stable during a test.
