Abstract

It is well known that the buckling strength of thin cylinder shells are mainly depends upon geometrical imperfections present on the thin cylindrical shells induced during manufacturing process. Hence it is necessary to measure these geometrical imperfections accurately, to predict the buckling strength of the cylindrical shells accurately. Using CMM to measure the geometrical imperfections is more accurate but costlier and also measurement depends on the operator’s skill. To overcome this problems an imperfection measurement rig is developed Using this measured imperfections data best fit surface map is generated, which can be used for further analysis.
