Dynamic Model Of Carbon Fiber Drive Shaft

摘要

The main goal of this paper is, that if we want to correctly identify dynamic model of drive shaft made of carbon-epoxy composite, we must take into account the influence of deformation velocity on elasticity characteristic. In the paper, Authors showed the effect of passing shaft resonance (1st critical speed). It was shown in the conditions of acceleration and braking with different increases of rotational speed. When examining the results obtained with empirical and model research, it has been shown that in the structural design of carbon fiber drive shafts, the main factor affecting the right development of the structure should be dynamic criterion, since the only use of static criteria leads to big errors.
