Excavator stability evaluation system and method, controller and excavator
The invention relates to an excavator, and provides an excavator stability evaluation system and method, a controller and an excavator in order to solve the problem that the existing excavator stability evaluation method is subjected to large subjective factors of a test operator. The method comprises the following steps: completing a plurality of set test actions on a plurality of excavators with known stability evaluation scores, and measuring the vertical displacement amplitude of a counterweight; establishing an evaluation score-counterweight displacement relation model through numerical fitting, wherein P = a1X1 +... + ai Xi +... + akXk; a plurality of set test actions are completed on the excavator to be evaluated, and the vertical displacement amplitude of the vehicle counterweight is calculated; and calculating the stability evaluation score of the excavator to be evaluated through the evaluation score-counterweight displacement relation model and the counterweight vertical displacement amplitude. According to the method, the evaluation score-counterweight displacement relation model is utilized to complete the corresponding set test action on the to-be-evaluated excavator to determine the stability evaluation score of the to-be-evaluated excavator, and the excavator stability evaluation score obtained through the method is relatively objective and real.
本发明涉及挖掘机，为解决现有挖掘机稳定性评价方法受测试操作员主观性因素大的问题，本发明构造一种挖掘机稳定性评价系统和方法、控制器和挖掘机，其中方法包括在多台稳定性评价分数已知的挖掘机完成多个设定测试动作并测量配重竖向位移幅值；通过数值拟合建立评价分数‑配重位移关系模型，P＝a1X1+……+ai Xi+……+akXk；在待评价挖掘机上完成多个设定测试动作并车辆配重竖向位移幅值；通过评价分数‑配重位移关系模型与配重竖向位移幅值计算得到待评价挖掘机的稳定性评价分数。本发明利用评价分数‑配重位移关系模型在待评价挖掘机完成对应的设定测试动作确定待评价挖掘机稳定性评价分数，通过该方法得到的挖掘机稳定性评价分数相对客观真实。
