The fatigue crash calculation and deterrence is very important for the conveyance/drive shafts which have to transfer weighty torque. Thus a correct design and the fixation methods should be taken to prevent the fatigue failure and to improve the fatigue life of the shaft.
In this work a complete study of an elevator drive shaft is done. The failure of the shaft has occurred at low stresses and high cycles due to the improper design of the failure prone areas (i.e. keyway slot). The different methods such as increasing the radius of curvature of the keyway slot, & by using boron composite the stress is condensed and the number of life cycles of the shaft is improved.
