Abstract: Ring stiffened cylinders usually weld ring frames along the circumferential direction to improve the stability. In this case, the frame tripping is of great significance to the overall stability of ring stiffened cylinders. According to the mechanism and the analytical solution of frame tripping, the relationship between the geometric parameters of ring stiffened cylinders and their elastic tripping pressure are analyzed both theoretically and experimentally. The contribution of different geometric parameters of ring stiffened cylinders is studied, and the effects of geometric parameters on frame tripping is finally obtained.
