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.

Abstract Due to the fact that the requirements of the industry aim to improve the dynamics, the safety and the comfort during the use of the vehicles, it is recommended to use the finite element method for component quality optimization. The purpose of this paper is to provide an overview of the current state of analysis through the finite element method of the crimping process used to assemble air springs produced in the automotive industry. Starting from the prototype of an air spring, the researches are focused on the study of the assembly of the piston with the bellow and the crimping ring through the crimping process. After analysis with the finite element method and static tests, improvements were made to the piston, the results of the tests revealing an improvement as opposed the original variant of the piston.

Element Method

Advanced engineering techniques for analysis are modern tools used for companies to enhance the design and manufacturing cycles of new or existing products. Finite element method has become one of the most used tools in the design process of products. This paper presents a case study regarding a design change of the brackets that support the gas jet in stoves. Using the finite element method, the mechanical performance of the existing brackets is compared with the performance of the new proposed bracket. This comparison is used to evaluate the feasibility of carrying out the design change. The benefit of the new design is a reduction of materials, production costs and production times. Experimental analysis of the materials and the validation of the finite element solutions were also performed. The results of the experimental analysis and FEM simulation are discussed and presented. Finally, the performance of the existing and the new brackets under several load cases is compared and the results suggest that the product design change is feasible.

In practice, gear units whose transmission number is not constant during one revolution are used. Such gears include the proposed elliptical transmission. Its application can be (missing a word?) and the automotive industry. The gears set consists of a pair of identical elliptical gears. The transmission ratio of the designed elliptical gear is not constant. The basic kinematic characteristics of this transmission are described in this work. The deformation in contact point of non - circular gears is determined by the finite element method in this paper. The results are compared with the deformation of the teeth of the spur gears.
