Abstract

The invention discloses a microcomputer controlled electro-hydraulic servo large multifunctional pressure shearing tester capable of providing a large single pressure load, a horizontal shearing force value for a large pressure shearing test and a vertical ejection force value for a large corner test and capable of applying a large stress ratio to simulate the actual condition. The test comprises a host (1), a hydraulic system (2), an electro-hydraulic servo control system (3) and a sample conveying trolley (4), wherein the host (1) comprises a frame, a vertical servo loading cylinder (105), a corner servo loading cylinder (104), a box-type pressing plate (103) and a horizontal shearing servo loading device (108), wherein the frame consists of a movable cross beam (101), four lead screws (102) and a base (106); the vertical servo loading cylinder (105) and the corner servo loading cylinder (104) are arranged on the base (106) at the bottom of the frame; the box-type pressing plate (103) is connected with a piston of the vertical servo loading cylinder (105) through a load sensor; the horizontal shearing servo loading device (108) is arranged on the right side of the frame; and the horizontal shearing servo loading device (108) is arranged on a movable trolley (109), a guiding device (107) for controlling lifting of the horizontal shearing servo loading device (108) is arranged on the movable trolley (109), and a synchronous floating servo cylinder (110) is arranged on the lower part of the movable trolley (109).

Description

technical field [0001] The invention relates to a large-scale multifunctional material compression shear test equipment. Background technique [0002] Large-scale equipment such as large passenger planes, giant ships, and offshore drilling platforms require mechanical performance testing and comprehensive test research on large structural parts or overall models; the rapid development of expressway and high-speed railway construction requires bridge plate, basin rubber The mechanical performance testing and comprehensive evaluation of the type bearing are carried out. In the prior art, presses and small conventional compression-shear test equipment are often used for measurement, but there is a problem that a large stress ratio cannot be applied to simulate the actual situation, and it cannot meet the diversification and large-scale construction of highways and railway bridges. Contents of the invention [0003] The invention provides a microcomputer-controlled electro-hy...
