Tip-over prediction method and tip-over early warning system for slope operation of excavator
The invention discloses a tipping prediction method and system for slope operation of an excavator, and belongs to the technical field of excavator control. The method comprises the steps that when the excavator works in a slope excavation mode, the inclination angle of a slope where the excavator is located is obtained; the gravity center position of the excavator and a first component force of the gravity of the excavator in the direction perpendicular to the slope are obtained based on the inclination angle; the actual tipping moment of the excavator is obtained, and the stable moment of the excavator is obtained based on the gravity center position of the excavator and the first component force of the gravity of the excavator; and judging whether the excavator can tip over or not in the current working mode at least according to the magnitude relation between the stable moment and the actual tip-over moment. The tipping early warning system provides a structural basis for time of the tipping prediction method. By means of the method, whether the excavator can tip over or not during slope operation can be predicted, the accuracy of tip-over prediction is improved, and the safety and stability of the excavator during slope operation are guaranteed.
本发明公开了一种挖掘机斜坡作业的倾翻预测方法及系统，属于挖掘机控制技术领域。方法包括：当挖掘机工作方式为斜坡挖掘作业，获取挖掘机所处斜坡的倾斜角度；基于所述倾斜角度获取挖掘机重心位置以及挖掘机重力在垂直于斜坡方向上的第一分力；获取挖掘机的实际倾翻力矩，并基于所述挖掘机重心位置以及挖掘机重力的第一分力，获取挖掘机的稳定力矩；至少根据所述稳定力矩与所述实际倾翻力矩的大小关系判断当前工作方式下挖掘机是否会倾翻。倾翻预警系统则提供了倾翻预测方法时间的结构基础。本发明能够实现对挖掘机在斜坡作业时是否会发生倾翻情形的预测，提升倾翻预测的准确度，保障挖掘机斜坡作业时的安全稳定性。
