Abstract:The effect of shock absorbers was investigated paring the measured dynamic responses of the mountain
bike frame mounted different shock absorbers subjected to harmonic excitation. The experimental results show that the per-
formance of the spring absorber is as good as those of the oil absorber and the gas absorber within specific frequency ranges.
The dynamic model of the mountain bike frame,which was verified by the experiment,was then developed to the whole
model of
