摘　　要：为揭示犁体表面与土体间的相互关系,探讨使用压力传感器阵列测试犁体表面所受土体压力的可行性。用自制的隔离盒分别将11个压力传感器封装后布置在犁体表面,形成传感器阵列,并将构建的系统置于流变态粘性土壤中进行测试。测试结果表明,该测试手段满足使用要求,其数据表明最大点荷载产生于犁铧的铧面上,最小点荷载产生在犁铧与犁壁的过渡区域。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.
