Abstract

The invention discloses a microcomputer controlled electro-hydraulic servo multi-functional pressure-shear test machine which belongs to the field of material test machines, and mainly solves the precision, speed and stress value problems of basic material performance test in the bridge construction. The machine comprises a main machine part, a hydraulic system, a control system and a specimen transportation car. The frame of the main machine comprises a stand, a screw rod, a movable cross beam, the frame and the like; the main machine is provided with a box-shaped pressure plate, a vertical servo loading oil cylinder, a horizontal shear servo loading oil cylinder, an angle servo loading oil cylinder, a synchronous floating servo oil cylinder, a cross beam lifting mechanism and a test device. The hydraulic system comprises a servo oil source, a hydraulic oil distributor and a remote pressure control system; the control system comprises an industrial personal computer, a conversion board, an electro-hydraulic servo control cabinet and a measuring instrument. The microcomputer controlled electro-hydraulic servo multi-functional pressure-shear test machine is used for the mechanical performance test to the middle plate-type and pot-type rubber brackets and spherical brackets in the bridge construction, such as single-pressure, pressure-shear and angle tests, and can take single-pressure test to metal and other non-metal and concrete components.

Description

technical field [0001] The invention relates to a material testing machine, in particular to a microcomputer-controlled electro-hydraulic servo multifunctional compression-shear testing machine used for component testing in highway and railway bridge construction. Background technique [0002] In the construction of highways and railway bridges, there are many types of rubber bearing products, large volume, high precision requirements, and many testing items. The existing testing machines have small load capacity, single function, and testing accuracy cannot meet the requirements. At present, there is no one at home and abroad. Test equipment that comprehensively and systematically meets these requirements. With the rapid development of economic construction, the number of large-scale bridge construction projects has increased, and higher requirements have been put forward for building components such as bearing capacity and service life. needs. Contents of the invention ...
