摘要

现有复合挖掘力模型缺少对实际作业中挖掘阻力存在阻力矩的考虑，导致计算的复合挖掘力偏小，不能反映真实作业中挖掘机的复合挖掘性能。因此，基于挖掘阻力特性建立了以阻力矩和复合挖掘力方向角的主值区间为依据的极限复合挖掘力模型，选取某22 t反铲液压挖掘机任一常态复合挖掘轨迹，求解其挖掘阻力和不同理论挖掘力模型的挖掘力大小，证实了极限复合挖掘力在挖掘作业中是最大的。此外，基于某36 t反铲液压挖掘机两种不同工况的实际挖掘轨迹求解了不同理论挖掘力模型的轨迹挖掘力和主挖区内图谱挖掘力。结果表明：极限复合挖掘力模型能更为确切地表征复合挖掘轨迹挖掘力性能，并给出挖掘轨迹的最佳理论挖掘力表征方式。主挖区图谱挖掘力表明不同挖掘方式不同作业域所发挥的最大挖掘力是各有差异的。

Abstract

The existing compound digging force model of hydraulic excavators does not take into account the existence of resistance moments in the actual work of the digging resistance

which results in the calculated compound digging force being smaller and does not reflect the compound digging performance of the excavator in real operation. Therefore

this paper proposes a limit compound digging force model based on the main value interval of the resistance moment and the directional angle of the compound digging force. Selecting any normal compound digging trajectory of a 22 t backhoe hydraulic excavator

its digging resistance and the digging force size are calculated by the proposed model and other theoretical digging force models respectively

and it is verified that the limit compound digging force is the maximum in the digging operation. In addition

based on a 36 t backhoe hydraulic excavator

the trajectory digging force of different theoretical digging force models and the digging force of the main digging area map were solved for the measured digging trajectories under two different working conditions. The results show that the limit compound digging force model can more accurately characterize the digging force performance of the compound digging trajectory

and give the best theoretical digging force characterization of the digging trajectory. The main digging area mapping force shows that the digging force exerted by different digging methods in different working areas is inconsistent.
