The utility model discloses a belong to a be used for measuring soil compacting test platform of agriculture farming technique scope, this test platform sets up the soil box at a soil within range, and the soil box size is tire - soil contact trace, when laying the sensor in the soil box, lays according to becoming " right angle " respectively along two orientations in tire walking orientation and the perpendicular to tire walking orientation, discloses tire - soil contact distributing of stress law through answer the force measurement to two orientation soil, through the section to being surveyed soil, measure different degree of depth soil layer stress intensities to revea soil stress transfer law, the utility model discloses an experiment is accomplished under the agricultural machine operational environment of field, and true, the objective embodiment agricultural machine of experimental enviroment is to the field soil condition of rolling. Carried out the simplification analysis to soil stress state, made complicated soil stress state become and simply easily summarize the law. |
