英文摘要：

To solve the high-speed, high-precision anti-axial drifting problem of automatic ultrasonic testing support system for the cylinder in nuclear, an anti-axial drifting mechanical adjustment mechanism which has the characteristic of spatial deflection adjustment is designed and developed. A mathematical model of the relationship between the support system and the cylinder axial drifting is established, the influence of the support system adjusting angle on the angle between the roller and the cylinder is analyzed through the model simulation. To solve the matching problem between cylinder spiral motion and roller, a loop adjustment system based on the axial force negative feedback is proposed, the accurate control of the cylinder axial drifting is achieved.
