| 摘 要： | 基于CFD软件Fluent提供的计算方法,利用动网格技术和UDF(用户自定义函数),对差压式管道内检测机器人启动过程进行了动态模拟.该方法克服了以往静态研究的不足,更直观地反映了不同因素影响下机器人的启动情况.仿真结果表明:管内流体速度、机器人质量、管壁摩擦力、不同流体对机器人的启动过程都有明显影响.可为下一步研究机器...

| Abstract: | By the aid of the numerical methods offered by CFD software Fluent,physical models,dynamic mesh model and UDF(user-defining functions),the method of dynamic numerical simulation is studied to explore the start-up process of differential-pressure-driven in-pipe inspection robot.This method can overcome the limitation of the previous static study,and can directly reflect the real start-up process of the robot under the influence of different factors.The result of simulation indicates that the start-up process... |
