    摘要:

    為揭示犁體表面與土體間的相互關(guān)系,，探討使用壓力傳感器陣列測試?yán)珞w表面所受土體壓力的可行性。用自制的隔離盒分別將11個壓力傳感器封裝后布置在犁體表面,，形成傳感器陣列,，并將構(gòu)建的系統(tǒng)置于流變態(tài)粘性土壤中進(jìn)行測試。測試結(jié)果表明,，該測試手段滿足使用要求,，其數(shù)據(jù)表明最大點(diǎn)荷載產(chǎn)生于犁鏵的鏵面上,，最小點(diǎn)荷載產(chǎn)生在犁鏵與犁壁的過渡區(qū)域,。

    Abstract:

    In order to reveal the relationship between surface of plow and soil, the feasibility of using the sensors to test the force on the plow surface was discussed. 11 sensors were packaged in the self-isolation boxes and arranged in the surface of plow to form a sensor array. And then the system was put into the paddy soil for testing. The result showed that proposed method met the practice demand. The data showed that the maximum load was on the plowshares spade, and the minimum load was in the area of the transition from plowshare to the wall.
