为了研究SWE210型挖掘机无故障状态下在平硬路面上的行走跑偏特性,在Recur Dyn中建立了挖掘机动力学模型,对其进行了低、高速挡工况下在平硬路面上的行走跑偏数值模拟,并进行了行走跑偏试验,数值模拟与试验结果较好吻合。研究结果表明:SWE210型挖掘机以低速挡在平硬路面上行驶时,跑偏量与行走距离大致服从线性分布,但在高速挡下并不服从;当行驶距离相同时,低速挡下的挖掘机行走跑偏量明显小于高速挡下的行走跑偏量;运用Recur Dyn对挖掘机进行行走跑偏仿真具有较高精度,为今后挖掘机行走效率的研究和挖掘机履带系统的结构优化提供了一种新的方法。

In order to study the deviation characteristic of SWE210 excavator while it running on the level and hard road, its dynamic model was built by using Recur Dyn. And then, numerical simulation on running deviation of the excavator while it driving on the level and hard road at low speed and high speed, and test for running deviation was conducted. The numerical simulation results were close to the test ones. The study results showed: while SWE210 excavator driving on the level and hard road at low speed, the running deviation was a linear function of driving distance, although was not at high sp...
