Abstract
The aim of this paper is to study the behaviour of a gas-filled LPG (liquefied petroleum gas) cylinder having dissimilar heads (hemispherical, semi-ellipsoidal and tori-spherical) and its responses subjected to vertical (at the top) and horizontal (side) normal impacts by a solid spherical steel ball of mass 4 kg at different velocities 5, 25 and 50 m/sec using ANSYS. The technical specifications of the gas cylinder necessary for its design calculations are referred from Hindustan Petroleum Corporation Limited (HPCL). The conventional steel is considered as the material for both the cylinder and the impacting ball under the critical gas pressure of 2.5 MPa as per Indian standard, IS 6240. Effects of the critical gas pressure on the cylinders are studied based on the thickness as well as the strength for above heads. The simulated results of ANSYS have good agreement with the theoretical results.
