The performance estimation about such cycle parts as frame tubes and wheels is discussed. Continuum bodies are employed as the mathematical models and the model parameters are obtained as to minimize the errors between analytical results and experimental. A wheel is looked upon as a ring model supported by elastic springs. The accelerance for the flexural and torsional vibration is formulated based on the model by Fourier series. The flexural rigidity, shear rigidity and damping ratios for the model are identified using experimental results and examined. A frame tube is regarded as Timoshenko beam model. The accelerance for the flexural vibration is formulated based on the normal mode method. The Young's modulus, shear modulus, damping ratios, the flexural rigidity and the shear rigidity are identified and the performance is examined.
