Problems solved by technology
[0004] The above-mentioned vehicle ground mechanical parameter measurement device can only detect the pressure-bearing properties of the soil, and the mechanical properties of the soil include shear properties in addition to the pressure-bearing properties. This device cannot measure the shear properties of the soil, and cannot comprehensively obtain the mechanical parameters of the soil; Moreover, the device manually measures and records the press-in displacement of the pressure plate by the staff, and the measurement accuracy is poor

The invention discloses a vehicle ground mechanic parameter measuring device, which comprises a shell (2), a pressure and torque load transmission mechanism arranged in the shell (2), and a pressure plate (1) arranged on the lower end of the pressure and torque load transmission mechanism, wherein the pressure plate (1) is contacted with the ground; and the pressure and torque load transmission mechanism applies pressure and torque to the pressure plate (1). Thus, the measuring device alone can realize the measurement of the pressure bearing capacity of the ground and the shearing property ofthe ground, and thus, the overall measurement of vehicle ground mechanic parameters by one device is realized.
Description
technical field [0001] The invention relates to the technical field of soil parameter measurement, in particular to a vehicle ground mechanical parameter measurement device. Background technique [0002] During the driving process of the vehicle on the road, the road is used as a supporting surface, and the soil on it interacts with the wheels or crawler belts and other running mechanisms. The specific performance is: the soil produces a certain subsidence displacement under the action of the vehicle's gravity, and exerts a certain impact on the vehicle. The driving acts as a hindrance; at the same time, the running mechanism provides the required traction for the vehicle to move forward through the frictional shearing of the soil. If the soil mechanical properties are good, the soil subsidence displacement is small under the same pressure, and the obstruction to the vehicle is also small, and the traction force provided is also large, so the vehicle is easier to pass; on th...
