Description

Technical Field

[0001] The present application relates to a 2000-ton microcomputer-controlled electro-hydraulic servo dynamic compression and shear testing machine, which belongs to the technical field of dynamic compression and shear testing. Background Art

[0002] During the test of the dynamic compression and shear testing machine, the lateral and vertical load sensors are affected by different tangential forces, thus affecting the accuracy of the experimental data. The dynamic compression and shear testing machine uses a cylinder to control the upper pressure plate to move up and down. The upper pressure plate is connected to a load sensor, which is fixed on the piston of the cylinder. The movement of the cylinder piston drives the movement of the upper pressure plate. In this method, the cylinder and the sensor are easily damaged by lateral forces. The traditional method of the dynamic compression and shear testing machine is to use a split base or a welded base. This method will cause a gap to have a greater impact on the test results in the horizontal direction after long-term use. The dynamic compression and shear testing machine also has the problem of the trolley tilting when the limit shear is applied. Therefore, in order to solve these shortcomings, it is necessary to develop a new 2000-ton dynamic compression and shear testing machine. Utility Model Content
