摘　　要：蔬菜移栽机作业环境复杂,履带式底盘可为其行走作业提供更好动力。为了研究履带式蔬菜移栽机工作时的功率,确定工作参数,为移栽机电机选型提供指导,确定移栽机工作时的负荷,需要获取移栽机工作过程中行走半轴的载荷数据。针对履带式蔬菜移栽机行走半轴的载荷数据,采用无线传感测试技术,分析了扭矩测试的原理,选择了合理的测点布置方案,搭建了一套用于测试履带式蔬菜移栽机底盘行走扭矩的无线测试系统。以履带式蔬菜移栽机为试验样机进行了田间试验,结果表明,试验所搭建的载荷测试系统的线性度为0.14%F·S,而重复性误差则为0.26%F·S,可靠性较高。将实时测试的扭矩信号与线性方程拟合后表明:履带式移栽机在田间作业时半轴扭矩表现出最高值,其中直线、右侧转弯、左侧转弯的扭矩分别为202、253和-233 N·m;在水泥路面行走时半轴扭矩表现为最低值,其中直线、右侧转弯、左侧转弯的扭矩分别为122、196和-183 N·m。The operational environment for vegetable transplanting machines was complex,and thetracked chassis could provide superior power for their mobility tasks.In order to study the power output of the tracked vegetable transplanter during operation,determine the working parameters,and provide guidance for the selection of the transplanter motor and determine the operational load of the transplanting machine,it is necessary to obtain the load data of the walking half axis during the transplanter's operation.Based on the load data of the walking half axis of the tracked vegetable transplanting machine,wireless sensing testing technology was used to analyze the principles of torque testing and select a suitable torque testing system.The wireless testing system was established for testing the walking torque of the chassis of the tracked vegetable transplanting machine.The filed experiment was conducted by the tracked vegetable transplanting machine,the results showed that the linearity of the load testing system was 0.14%F·S,and the repeatability error was 0.26%F·S,indicating good reliability.Fitting the real-time test torque signal and linear equations showed that the half axis torque of the tracked transplanting machine showed the highest value in the working field,with the torque for straight,right turn,and left turn at 202,253,and-233 N·m,respectively.The half axis torque of walking on a cement road surface exhibits the lowest value,with torques for straight,right,and left turns at 82,196,and-143 N·m,respectively.
