拖带法测量悬挂农具工作阻力不同操作方法的误差分析

Error analysis of different operation methods on measuring the work resistance of mounted equipment with the drawing method

用拖带法测量悬挂农具工作阻力，采用不同操作方法的测量结果有很大差异－ 本文从三杆力合成法与拖带法２ 种方法的统一性出发，分析了２ 种操作方法的误差。

To measuring the work resistance of the hang dead stock with the drawing method,different standards of the measuring methods cause great difference within the measuring results.Based on the intercommunity between the resultant method of the three shaft force and the drawing method,analysis was carried out on the error of two operation methods,it is thought that the correct measuring methods is the general drawing resistance of unit minus the air rolling resistance of the tractor with farm tools unloaded.
