DETERMINATION OF OPTIMAL DIMENSIONS OF VEHICLE CRASH-PROOF BODY
Design moment of good holes strengthening in the spherical shell was offered. It was found a design equation, which allows determining dimensions of cylindrical strengthening, which eliminates stress concentration in the spherical shell of submersible craft crash- proof body. Formulas for durability and cylindrical strengthening of holes stability check-up were suggested. It was given recommendation about strengthening of holes family in the spherical shell, which is situated side by side.
