The kinematics analysis and mechanical property of the robot is carried out in this paper,in order to obtain the motion lawof the new ly developed pipeline robot,verify its motion state and work characteristics.Theoretical modeling and simulation analysis based on ADAMS software are used to get the motion law curve of the pipeline robot and obtain the change rule curve of the piston driving force when the robot moves in the pipeline.Results show s that the robot can adapt to the pipeline diameter range of 750~1 057.5 mm,and the step distance is 103 mm with smoothspeed and acceleration curve,stable operation with no tremor phenomenon;When the load force is4 000 N,from the driving force change curve,the driving force change range of the telescopic clamping mechanism is 1 407.6~18 113.7 N.The driving force range of the stepping element 1 978.46~7 645.38 N,driving force curve smoothing and inability to shock with good drive performance.The kinematics performance and mechanical property of the new type of pipeline robot is verified and meet the functional requirements.It is indicated that the new pipeline robot has the advantages of adapting to the large diameter range,stable movement,and high-driving performance.
