This study aims to examine and compare the
strength performances of vehicle cylindrical liquefied petroleum gas (LPG)
tanks produced and used in Turkey, taking into account European and Turkish
Standards. The LPG tanks were subjected to burst and fatigue tests to explore
their burst pressures and fatigue performances using both experimental and
computer aided techniques. To investigate the strength of the tanks, a
universal test bench was developed and calibrated for use in both burst and
fatigue tests. The obtained experimental results in terms of burst and fatigue
failure locations for each brand of tank are compared with the results obtained
using finite element based simulations. Visual solid models in 3D were drawn in
SolidWorks and then ANSYS software was used to perform FEA simulations on those
LPG cylinders to obtain the results, such as stresses, deformations, burst and
fatigue failure locations. As a result of this comparison, it has been observed
that some brands of cylindrical LPG tanks are more durable and safe for use in
vehicles. Since the same standard requirements and the same commercial material
are used in LPG tank production, it is revealed that some companies need to
reconsider their design, manufacturing and especially welding processes. The
results of this independent and objective study can also be used as a warning
for LPG tank manufacturers and a guide for their customers in choosing safe
products.
