Abstract

The invention relates to a soil strength test board for a wheel. The soil strength test board for the wheel comprises a test board bracket, a wheel and a soil groove body which interacts with the wheel, the soil groove body is arranged at the lower part of the inside of the test board bracket, and the wheel is located at the upper surface of the soil groove body in a rolling press mode; the wheel is connected below a variable load mechanism through a steering mechanism, and the variable load mechanism is connected with a driven wheel drive mechanism through vertical and horizontal moving mechanisms so as to be movably hanged on two upper beams of the test board bracket; the rotating shaft of the wheel is directly connected with an active wheel drive mechanism. The soil strength test board for the wheel can use a counterweight block to change the weight of the soil strength test board for the wheel under an offline state so as to simulate the acting force between the wheel and the ground under different vehicle weights; a slider-crank mechanism changes the distance between two isotropic magnets so as to change the repulsive force there-between to simulate the online real-time vertical load change of the wheel of an air cushion vehicle; the active wheel drive mechanism and the driven wheel drive mechanism simulate the active movement form and driven movement form of the wheel.

Description

technical field [0001] The invention relates to a wheel soil force testing platform, in particular to a wheel soil force testing platform capable of changing the wheel-ground vertical force in real time on-line. Background technique [0002] There are large swamps, tidal flats, deserts and other soft ground environments on the surface of the earth, involving many industrial and agricultural sectors such as petroleum, mining, transportation, fishery, forestry, agriculture, and military fields. When off-road vehicles are running on soft ground, the running mechanism is prone to deep sinking, high resistance, low efficiency, severe skidding, and even inability to drive at all. Therefore, it is necessary to design and develop a soil force test bench for the study of running ) and soft soil, and optimize the design of the walking mechanism based on this to improve the soft ground passability. [0003] The following issues should be considered in the design scheme of the wheel so...
