| 摘 要： | 以轮式WZ30-25型液压挖掘装载机为实例，基于多刚体系统动力学理论，在三组反铲机构液压缸的运动作用下，研究了挖掘装载机整机系统在铲斗斗齿切向产生的挖掘力响应。在斗杆液压缸挖掘和铲斗液压缸挖掘两种工况下，进行了挖掘力响应分析。在各工况下，影响挖掘力的重要参数有很多，包括液压系统的压力、液压缸的尺寸、各液压缸间的相互作用力、整机稳定性和地面附着性能。将推导这些因素和最大挖掘力之间的函数关系。

| Abstract: | WZ30-25 backhoe loader was instanced by means of multi rigid-body dynamics theory. The whole system response to tangential digging force on bucket teeth was discussed in action of three sets hydraulic cylinder of backhoe mechanism. At two working conditions of digging with arm cylinder and with bucket cylinder, the digging force was analyzed. At each working condition, many important factors affect digging force. These factors are included the system hydraulic pressure, the dimension of hydraulic cylinder, the interacting force of hydraulic cylinders, the whole system stability and ground adhesive property. The function among these factors and the maximum digging force were inferred in this paper. |
