Research on the Engineering Mechanics Equations of a Pipeline Robot Supported by Wheel Systems

Existing oil pipeline robots generally face stability and adaptability problems in complex terrain and different environmental conditions. Especially under high load and complex pipeline paths, the robot's motion control and mechanical response often cannot meet the requirements. To this end, this paper first constructs a mechanical model of a supported wheeled robot in a pipeline environment. By analyzing the response of the robot under different terrain and disturbance conditions, a set of control methods based on dynamic optimization are proposed. This paper accurately calculates the contact force and motion trajectory of the robot on the pipeline by establishing a multi-factor coupling model including normal force, tangential force and friction force, and simulates and verifies its performance under different operating conditions. The study also deeply analyzes the dynamic response of the robot under speed and slope conditions to ensure its efficient movement in difficult environments. The experimental results show that the robot's motion control accuracy has been significantly improved through the improved mechanical model, especially in pipeline environments with high-speed movement and complex slopes. Under flat conditions, the robot has a recovery time of 2.1 seconds after being disturbed by a speed of 0.5 m/s, a maximum displacement deviation of 0.15 meters, and a maximum posture deviation of 3.5°.
