摘要
针对乌梁素海特殊的水域特征以及挖掘底泥对延缓其沼泽化的重要意义和所带来的经济价值,运用三维建模软件Pro/E和动力学分析软件ADAMS对抓斗式挖掘装置进行虚拟设计研发,利用惩罚函数法对抓斗的结构尺寸进行了优化。通过Pro/E对优化后的抓斗进行受力分析和有限元分析,装配其组件后模仿真实挖泥时的运动情况,进行干涉检验;采用“无缝连接”的技术,利用ADAMS和Pro/E的专用接口Mechanism/Pro,将Pro/E建好的三维模型直接导入到ADAMS界面下,避免了数据丢失;在ADAMS中添加复杂约束、载荷和摩擦力等,模仿真实的运动情况;利用ADAMS/Processor对得到的数据进行后续处理,分析绘制出的开斗张开角曲线图、侧液压缸受力变化曲线图和主液压缸受力变化曲线图等,为设计制造提供了理论依据。
As for Wuliansuhai lake＇s features, it has great significance and economic value to mine sediments for delaying marsh, 3D model software Pro/E and dynamic analysis software ADAMS were used for developing the virtual design of excavator. The construction size of grab was optimized by using the penalty function. Force analysis and finite element analysis were conducted for optimizing grab by using Pro/E. The actual movement of grab when working has been simulated and interference test has been done after assembling their components. Using special interface MECHANISM/Pro between Pro/E and ADAM, Pro/E 3D model has been transferred directly into ADAMS to avoid data loss by the ＂seamless link＂ technology. The real movement has been imitated after adding complicated constraints, load, and friction. The opening angle curve of the open struggle, pressure changes curve of the hydraulic cylinder, and pressure changes curve of the main hydraulic cylinder, which provide a theoretical basis for the design and manufacture, have been analyzed and mapped out with ADAMS/processor.
