摘要
通过采集液压挖掘机作业轨迹等参数,基于Altair软件Activate和Motion模块,建立挖掘机机构-结构-液压-控制多学科协同仿真模型,以挖掘机作业轨迹为控制目标,对比分析动臂油缸、斗杆油缸、铲斗油缸仿真和试验的受力情况,结果表明:仿真与试验的受力趋势相同,动臂油缸作用力平均偏差为5%、斗杆油缸作用力平均偏差为2%、铲斗油缸作用力平均偏差为2%.研究表明,基于多学科协同仿真的挖掘机模型,可以很好地模拟挖掘机作业时的油缸受力情况,该模型可减少试验次数、降低试验成本,同时为挖掘机结构优化设计提供载荷数据,具有一定的工程意义和价值.
Abstract
Based on Altair software Activate and Motion module,a multidisciplinary collaborative simulation model of excava-tor mechanism-structure-hydraulic-control was established by collecting parameters such as the working track of the hydraulic excavator.Taking the working track of the excavator as the control target,the stress conditions of the boom cylinder,bucket rod cylinder and bucket cylinder were compared and analyzed.The results show that:The stress trend of simulation and test is the same.The average deviation of acting force of boom cylinder is 5%,that of bucket rod cylinder is 2%,and that of bucket cylinder is 2%.The research shows that the excavator model based on multidisciplinary co-simulation can well simulate the stress condi-tion of the cylinder during excavator operation.The model can reduce the number of tests,reduce the cost of tests,and provide load data for the optimization design of the excavator structure,which has certain engineering significance and value.
