Design of a fuel tank in Volvo frontloader L120 : Effects of the baffles on reducing liquid sloshing

Abstract:

Sloshing phenomena could seriously damage tank structures and reduce its

lifetime. On the one hand, studies directly recommend the use of baffles to

solve these problems, nevertheless on the other hand the existence of small

tanks or plastic tanks without baffles confuse and complicate the case.

The first aim in this thesis is to clarify the necessity of baffles for a particular

diesel tank L120 H-Generation in Volvo front loaders. Then, the second aim

is to improve the existing design.

Four configurations are proposed and checked independently. Experiments in

the lab, FEM static stresses analyses and vibrational simulations are done in

order to fulfill the requirements.

The conclusion of this thesis is that the dissipation of energy is highly

recommended, so having an oblique baffle with holes could be a good way to

reduce the sloshing and extend the lifetime of the tank.
