Abstract

The invention discloses a multi-angle measuring device for the adhesion coefficient between an animal foot and soil. The device comprises a soil forming device, a force and displacement measuring device and an animal foot fixing device, a to-be-tested ground environment is prepared in a soil tank of a ground forming device, the animal foot is fixed on a detachable type flange plate of an animal foot fixing device with quick-drying concrete, the flange plate is fixed on a moving disc, a displacement sensor of the force and displacement measuring device is reset, the animal foot is loaded in the vertical direction, and then horizontal load is slowly applied to the soil tank. The change relation of the horizontal direction force and the displacement can be obtained, and the adhesion coefficient of the animal foot on the soil is obtained by dividing the maximum force borne by the animal foot bottom with the maximum horizontal force. When the adhesive force is measured, the loading speed is 2mm / min and very small, and accordingly, no effect to the inertia force exists. The device structure 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 ...
