Abstract
The invention discloses a comprehensive measuring device for the shear mechanical behavior of the metal disk-soil interface and a method for using it, including a test bench, a hydraulic loading system and a shearing system, the hydraulic loading system includes a load-bearing bracket and a hydraulic oil cylinder, and the load-bearing bracket is fixed On the test bench, the hydraulic cylinder is fixed on the beam of the load-bearing support. The top of the sample chamber is equipped with a loading plate that is adapted to it and has a drain and exhaust valve. The top of the loading plate is connected to the piston rod of the hydraulic cylinder; The sample chamber is equipped with a water pressure hole, a hole pressure gauge, a drainage hole and a heating device, and the water pressure hole is connected with the steam-water exchanger; a temperature sensor is set on the shear disc, and a torque sensor is set on the rotating shaft of the servo motor. A sensor and a rotational speed sensor, a hole pressure gauge is arranged on the side wall of the sample chamber, and a pressure sensor is arranged between the piston rod of the hydraulic cylinder and the loading plate. The invention realizes the measurement of the shear mechanics behavior between the metal interface and the soil body under the conditions of different soil pressure, different water heads, different temperatures and different shear speeds.
Description
technical field [0001] The invention relates to a metal disc-soil interface shear mechanical behavior measurement device, in particular to the metal disc-soil interface shear mechanical behavior measurement of soil samples under high temperature and high water pressure. The invention also relates to the use method of the device for measuring the shear mechanical behavior of the metal disc-soil interface. Background technique [0002] The shear mechanical behavior between metal and soil is a relatively traditional problem, which is very common in production and life. In agricultural production, too much soil adheres to agricultural machinery, which greatly reduces the working efficiency of agricultural machinery and consumes a lot of energy. The increase will seriously affect the quality of farming and the life of machinery; once the soil is adhered to the working surface of industrial machinery such as excavators and bulldozers, the efficiency of digging and bulldozing will ...
