Explain the Basic requirement of Design of shock transmission unit?
The STU must withstand the specified design load. The stroke of the piston must be bigger than the movement of deck due to temperature, shrinkage & creep in each direction of the deck's longitudinal movement. Just to give an idea about the movement of deck to the readers, the movement of the deck was for +40 mm to -90 mm. The maximum life expected for an STU is around 75 years subject to appropriate maintenance being performed by the user.
