摘要：

锻造操作机的行走定位精度和启停稳定性一直以来是大型锻造设备中的重要参数。通过搭建5 t锻造操作机行走动力学和液压系统的仿真模型，利用AMESimADAMS联合仿真的方式，采用更为准确的负载来研究操作机行走系统的主要液压元件对行走定位精度和启停稳定性的影响。联合仿真结果表明，液压管道、行走溢流阀、泵头溢流阀、比例换向阀等元件均能对锻造操作机的行走定位精度和启停稳定性产生一定的影响，为了提高行走定位精度及启停稳定性，应综合考虑液压系统中各元件的影响，对液压元件进行合理匹配。此研究可为锻造操作机行走系统的后续研发设计及优化改进提供理论依据。

The travel positioning accuracy and start-stop stability of forging manipulator are always important parameters in large forging equipment. Therefore, by building the simulation model of walking dynamics and hydraulic system for 5 t forging manipulator, using the AMESim-ADAMS co-simulation method, the influences of main hydraulic components of manipulator walking system on the travel positioning accuracy and start-stop stability were studied by more accurate load. The co-simulation results show that hydraulic pipeline, travel relief valve, pump head relief valve and proportional directional valve all have certain influences on the travel positioning accuracy and start-stop stability of forging manipulator. In order to improve the travel positioning accuracy and start-stop stability, the influence of each component in the hydraulic system should be considered comprehensively, and the hydraulic components should be matched reasonably. Thus, it can provide a theoretical basis for the subsequent development, design and optimization of the walking system for forging manipulator.
