Abstract
The automotive industry is one of the largest consumer of flexible hoses for fluids such as fuel or cooling. In order to limit the post production costs, every aspect of a vehicle must be tested in advance, including the lifespan, durability or failure of hoses. Throughout this paper summary results are presented for 4 types of fuel line hoses tested under controlled displacement loads at various pressures in order to validate the Finite Element Method simulations.
Highlights
The automotive industry is one of the largest consumer of flexible hoses for fluids such as fuel or cooling
Neoprene fuel hoses or PVC are offering a reliable alternative that can better handle the corrosive nature of the fuel
In order to assess the mechanical behavior of such hoses with Finite Element Method (FEM) software, 4 types of hoses were subjected to cyclic buckling under various pressure loadings
Summary
RAMONA NAGY*, REMUS STEFAN MARUTA, MIHAI HLUSCU, KAROLY MENYHARDT Politehnica University Timisoara, 2 Victoriei Sq., 300002, Timisoara, Romania. Neoprene fuel hoses or PVC are offering a reliable alternative that can better handle the corrosive nature of the fuel. This application imposes large static and time-varying strains over a long time [9]. To address the issue effectively and economically, engineers need to model and design for mechanical behavior early in the product development process. This need was partially addressed by the development of simulation software capable of predicting stress and strain histories but, real life input and output values are crucial for the relevance of the simulation [10-12]
