Abstract

The performance estimation of carbon tubes used in bicycle frames are discussed. Though several bicycles have a carbon frame, the builder does not know how to estimate the performance very much and depends on his experiences about the finishing. As important fundamental characteristics that the frame should have, we take the flexural and torsional rigidity of the tubes and evaluate the corresponding elastic constants by the parameter identification. The elastic constants are determined as to minimize the error between the experimental natural frequencies and the analytical. The results show that the CrMo material is still superior to the high elastic carbon tubes in both the flexural and torsional characters.
