基于PRO/E和ADAMS的清淤装置动力学分析

摘要

3D model software Pro/E and dynamic analysis software ADAMS were used for developing the virtual prototype design of Dredging Equipment. Using special connection 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 unit, density, rigid body and option of transforming have been solved when model was transferred. Real movement has been imitated after adding complicated constraints, load, friction. The opening angle curve of the open struggle、pressure changes curve of the main hydraulic cylinder, which provide a theoretical basis for the design and manufacture have been analyzed and mapped out by ADAMS/processor.%运用三维建模软件Pro/E和动力学分析软件ADAMS对清淤装置进行虚拟样机设计。采用“无缝连接”技术，利用ADAMS和Pro/E的专用接口Mechanism/Pro模块，将Pro/E建好的三维模型直接导入到ADAMS界面下，解决了模型传递过程中单位、密度、刚体设置，转化时的选项及曲线丢失问题，避免数据丢失。在ADAMS中对模型添加复杂约束、工作载荷及摩擦力等模仿真实运动情况，利用ADAMS/processor对得到的数据进行后续处理，分析并绘制出抓斗张开角曲线图、主液压缸受力变化曲线图等，为清淤装置设计制造提供理论依据。
