Estimation of stresses in system «massive – support – shaft drift» at dynamic loadings

Article preview

In article the question of dynamic influence on shaft drift a moving vessel is considered. Dependences of pressure in system «massive – support – shaft drift» from various in a direction and value of the loadings received by means of a method of final elements are resulted.

Justification of reliability of cantilever-rope reinforcement of deep shafts

Article preview

A possibility of combined operation of the rope and console shaft armouring is studied. A device is offered to secure their combined operation. Calculation dependences are given to assess stress in the device elements as well as graphical dependences to select sizes of these elements.
