Virtual Prototype Modeling and Dynamics Simulation of Working Device of Multifunctional Drilling Rig

为了分析多功能钻机工作装置的动力学特性,运用Solid Works和ADAMS建立钻机工作装置虚拟样机模型。对3种典型动作进行动力学仿真,获得各变幅液压缸受力变化曲线,并通过实验研究验证了仿真模型和仿真结果的可靠性和有效性。在此基础上获得钻机工作装置极限工况下的动力学特性,为钻机工作装置控制系统设计、结构优化设计及有限元强度分析提供可靠的参考。

In order to analyze the dynamic characteristics of multifunctional drilling rig′s working device,the virtual prototype model of drilling rig′s working device was established by SolidWorks and ADAMS.The stress change curve of each luffing hydraulic cylinder was obtained through the dynamics simulation of three typical actions.And then,the experiment research confirmed that the simulation model and result are reliable and effective.On this basis,the dynamic characteristics of drilling rig′s working device under the extreme working conditions were obtained,which provides reliable references for the control system design,structural optimization design and finite element strength analysis of drilling rig′s working device.
