Abstract

In the conventional calculation approach, it was low precision for large hydraulic excavator crawler driving system. So, a co-simulation approach should be presented. In this paper, software RecurDyn was used to run the dynamic model of crawler driving system. The mechanical parameters of dynamic simulation were used to establish a data table, which was input to the hydraulic system model that established by the software SimulationX. Results of hydraulic system were obtained after simulation in both forward driving and backward driving working conditions. Comparing the simulation results with theoretical calculation results, it proved that this approach was more accurate and faster operational speed. Thus, it is a more accurate and practical approach for crawler system design of large hydraulic excavator.
大型液压挖掘机驱动系统建模与仿真
在传统的计算方法中,大型液压挖掘机履带驱动系统的计算精度较低。因此,应该提出一种联合仿真方法。本文采用RecurDyn软件对履带式传动系统的动力学模型进行了仿真。利用动态仿真得到的力学参数建立数据表,将数据表输入到SimulationX软件建立的液压系统模型中。对液压系统在前向驱动和后向驱动工况下的仿真结果进行了分析。将仿真结果与理论计算结果进行比较,证明了该方法具有更高的精度和更快的运算速度。从而为大型液压挖掘机履带系统的设计提供了一种更为准确实用的方法。
