| 摘 要： | 为全面分析某型挖掘机机液耦合复杂系统,提出了基于数字化虚拟样机的评估方法。利用Amesim软件中的HCD(液压元件设计)库,从元件设计的角度建立挖掘机的液压系统模型,使得模型与实际系统更加贴近。借助三维造型软件Pro/E建立挖掘机装配模型,利用Adams软件建立挖掘机动力学模型。通过软件接口技术使得液压系统模型与动力学模型相互关联,建立了挖掘机机液耦合仿真模型。通过挖掘机样机试验测试,结果表明仿真数据与试验数据基本一致,验证了联合仿真模型的准确性。联合仿真模型可用于挖掘机系统方案设计、挖掘机样机性能评估,也可用于挖掘机系统优化的研究,为产品开发提供一种周期短、成本低的新方法。
