【Abstract】 A algorithm were developed for the statistical analysis of the draught control system for agriculturetractors. With this method the depth variance of plow,the variance of the revs and the torque of engine can be calculated, according to the given characteristic of stochastic disturbance. This algorithm can be adapted to the statistical analysis for the draught control system with top link sensing and unloading hydraulic circuit with pilof relief valve.更多还原
