油气管道爬行机器人的设计及仿真实验

针对新建无流体管道、非常规流体管道、分支管道和逆流体流向管道等特殊工况下,传统介质推动机器人无法完成作业的问题,对能够适应特殊管道工况的油气管道爬行机器人进行了研究,完成了一种气动式爬行机器人的详细设计,包括结构设计和控制系统设计等.利用ADAMS虚拟样机软件对油气管道爬行机器人在U型和90°管道的动力学进行了仿真分析.结果表明,该油气管道爬行机器人具有一定避障和过弯能力,可以完成油气管道特殊工况下的检测和维修.

Dynamic simulation of hydrokinetic hammer based on virtual prototyping technology

This study presented the specified steps of comprehensively analyzing the hydraulic-driven hammer system with the application of the Virtual Prototype Technology.By comparing the simulation results with experimental phenomena and data,the correctness of simulation analysis conclusion is verified.Meanwhile,by means of its perfect visualization,the internal work process which can not be seen before is simulated.The mechanism of some abnormal phenomena encountered during the experiment is explained.
