Excavator weighing method
The invention discloses an excavator weighing method, which comprises the following steps of: regarding a bucket filled with materials as a whole, and assuming a gravity center OG3 for the whole in a space coordinate; at a specific moment when a working device is static, moment balance equations are simultaneously listed for two different points by using the known quantity and the acquisition quantity, and the influence of hypothetical gravity center OG3 on solving of the weight G of a bucket filled with materials is eliminated after simultaneous listing. The total weight difference value of the materials and the bucket before and after the materials are unloaded is calculated, and the accumulative error influence of the residual materials in the bucket on the accumulative unloading amount is eliminated.
本发明公开了一种挖掘机称重方法，本方案将装着物料的铲斗看做一个整体，并给这个整体在空间坐标内假设一个重心OG3；在工作装置静止的特定时刻，使用已知量及采集量对两个不同点同时列出力矩平衡方程，联立之后消除了假设重心OG3对装着物料的铲斗重量G求解的影响。本发明分别计算物料卸载前后物料及铲斗总重量取差值，消除了铲斗内残余物料对累计卸载量的累积误差影响。
