Abstract

The invention discloses a multi-angle measuring device for the adhesion coefficient between the sole of an animal and sand and soil, which includes a sandy ground forming device, a force and displacement measuring device and an animal foot fixing device. The ground environment of the test, and then fix the animal foot with quick-drying cement in the detachable flange of the animal foot fixture, and fix the flange on the movable disc, and the force and displacement measurement device The displacement sensor is cleared, and the animal foot is loaded in the vertical direction first, and then the horizontal load is slowly applied on the soil groove. The relationship between horizontal force and displacement can be obtained, and the maximum value of horizontal force divided by the maximum force on the sole of the animal is the adhesion coefficient of the animal's foot on the sand. When the present invention measures adhesion, because the loading speed is 2mm / min, the loading speed is very small, so the inertial force has no influence. The structure of the device is simple and the measurement is convenient.

Description

technical field [0001] The invention relates to a device for measuring the adhesion coefficient between the sole of an animal and sand and soil, that is, a device for measuring the surface adhesion of sand and soil. Background technique [0002] The adhesion coefficient between the tire and the sandy ground directly reflects the passing ability of the vehicle on the sandy ground. At present, the improvement of the adhesion coefficient mainly starts from the ground contact area of ​​the tire and the tread pattern. However, in extreme environments such as deserts, the improvement of the adhesion coefficient between the tire and the sandy ground has encountered a bottleneck. [0003] There are many animals that can run fast on the sand in nature, such as ostriches and desert lizards. Humans began to turn to nature, get inspiration from nature, and tried to improve the adhesion between tires and sandy ground through engineering bionic technology. Engineering bionic technology ...
