摘要
针对大型正铲液压挖掘机工作装置工作范围和挖掘力的性能优化问题,首先采用ADAMS/view开发了液压挖掘机工作装置的运动学仿真模型,通过对其进行运动学仿真得出了挖掘包络图与工作范围性能指标,并通过调整铰接点位置的优化方法对工作范围的性能进行了优化;然后利用ADAMS/Hydraulics开发了正铲液压挖掘机工作装置液压模型,集成于工作装置运动学模型,从而建立了工作装置动力学模型,对其进行了挖掘力性能仿真研究,通过调整铰接点位置的优化方法对最大挖掘力进行了优化。研究结果表明,通过采用该仿真优化方法,提升了工作装置的工作范围与挖掘力的性能,筛选出的最终优化方案,将作为研发大型液压挖掘机的设计依据。
Aiming at the problem of performance optimization for the working range and the digging force of large face-shovel hydraulic excavator work device, kinematics simulation model of hydraulic excavator work device was developed by ADAMS/view firstly, to obtain the digging envelope diagram and the working range performance, through changing hinge point positions to optimize the working range performance. Then dynamics simulation on the work device dynamics simulation model was carried on, which integrated hydraulic model, that developed by ADAMS/Hydraulics, to research the digging force performance and optimize the biggest digging force by changing hinge point positions. The result indicates that this optimization method is an ideal approach to improve the performance of the working range and the digging force for the work device. The final optimization plan will become the design basis of research and development of large-scale hydraulic excavator.
