Analysis of mechanical resistance of water tank produced by rotomoulding.
Changes in the initial operating conditions of a water tank, drive to the client to request an evaluation of performance of the product.
The water tank have to operate buried and to preserve the dimensional characteristics, mechanical and functional resistance (cover opening).
Finite element analysis of the structural behavior of the cistern when buried in sand were carried out.
Results:
- the use of the numerical model allowed to analysis a variants of designs in shorter time than construct matrices, produce a prototype and test it in real conditions (trial and error procedure), representing a cost savings of 70% of the design process and considerably reducing developing time.
- a robust design was obtained that allows to buried the tank avoiding the collapse and conserving the functional characteristics (opening of the cover).
