Automatic regulation control method for rotating speed of hydraulic motor of electric loader
The invention discloses a method for automatically adjusting and controlling the rotating speed of a hydraulic motor of an electric loader. The method comprises the steps that rotating speed threshold values of a main hydraulic motor in different working states are set; the working state of the loader and the rotating speed of the main hydraulic motor are monitored in real time, whether the actual rotating speed of the main hydraulic motor is within a rotating speed threshold value or not is judged, and the rotating speed of the main hydraulic motor is adjusted in real time; recording and collecting motion states of a bucket of the loader in different working states, and establishing a load model; based on the load model, the current working state of the loader and the target rotating speed of the main hydraulic motor under different movement states of the bucket are calculated; the actual rotating speed of the main hydraulic motor is compared with the target rotating speed, and the rotating speed of the main hydraulic motor is adjusted in real time till the actual rotating speed and the target rotating speed reach the allowable error range; it is ensured that the rotating speed of the main hydraulic motor is matched with the actual load requirement, and therefore the main hydraulic motor can always keep the optimal operation state under various operation conditions.
本发明公开了一种用于电动装载机液压电机转速的自动调节控制方法，包括：设定主液压电机在不同工作状态下的转速阈值；实时监测装载机的工作状态和主液压电机的转速，判断主液压电机实际转速是否处于转速阈值，并对主液压电机的转速进行实时调整；记录收集装载机在不同工作状态下铲斗的运动状态，建立负载模型；基于负载模型，计算出当前装载机的工作状态和铲斗不同运动状态下主液压电机的目标转速；根据主液压电机的实际转速与目标转速进行比较，实时调整主液压电机的转速，直至实际转速与目标转速达到允许误差范围；本发明确保主液压电机的转速与实际负载需求相匹配，从而使主液压电机能够在各种操作条件下始终保持最佳运行状态。
