El segundo fueron las probetas de temple, revenido, recocido. No se observa la martencita. La parte oscura es cementita y la clara ensay. La parte oscura que se observa es Vainita y la parte clara Austenita. La diferencia de dureza al ser el mismo material puede deberse a que cada uno fue enfriado de diferente forma por lo que el material pudo haber modificado sus propiedades. Product design There are numerous studies on qualitative approaches in the product design.

A product design needs to take into account how the item will perform its intended functionality in an efficient, safe and reliable manner. The product also needs to be capable of being made economically and to be attractive to targeted consumers.

Business dictionary defines quality of design as level of effectiveness of the design function in. The DFQ process allows the engineer to: Design quality measures vary from organization to organization. They typically involve some.

Design process measures are metrics intended to quantify the. The ones quoted by the panel are: The essence of Lean is to eliminate waste in all aspects of product development and related. The term is derived from lean. The starting point is the customer’s requirements and determine the value added.

Mechanical Engineering TU Kosice done on a project of student car conducted by the author [9]. The car was taken by its originality, aggressiveness, speed, and innovative features modern. The project modelled the real process automakers, with the real constraints. The sequence of phases of the project were as follows: The new car was built on the Skoda Fabia platform. Body and interior are completely original.

The new solution is a hinged door opening. Other innovations are the engine and. The new car is shown in Fig. Project management was a crosscutting activity, as part of the student team was not experience of.

Lean design methods, because in conditions of university research projects are limited financial and. Design for quality, because the car represents the quality of student education in innovation and. It shows the conditions for their application in automotive research and. On impact, the structure of a vehicle has two main functions: These components in first instance are the vehicle bumper, and the initial section of the front rails of the vehicle see Figure 1 [5].

In most conventional vehicles the front rail is made up of two parts: The ideal behavior of the front structure of a vehicle would provide a constant resistance to deformation while not reaching the passenger safety cell.

This would cause a constant force producing deceleration that is not only great but which must also be bearable by the occupants. Various studies focus on the behavior of the axial crushing of tubes [6,7], where folding patterns of different geometries are studied, and the evolution of compressive force versus displacement is tested.

The study of geometry buckling initiators [8] is also very common. These are small predeformations in the tube that will achieve a reduction in the initial peak force for the collapse of the tube.

The use of buckling initiators is very common in crash boxes and in the initial section of frame rails in order to reduce the initial buckling force. Ehsayo distribution of energy absorption between different longitudinal components can be studied. Figure 2 shows a top view of the front of a car, where the distribution of energy absorption can be seen.

Within each of the two front rail components, 7. These energy absorption percentages would be different depending on the impact speed. If the velocity is not high, the components which are in the first half of the structure would be able to absorb all the kinetic energy, without deformation of the second half.

These percentages correspond to an impact that does not involve deformation of the passenger compartment and the impacted object is a rigid wall which does not absorb energy. Impact Performance of Minicars. Now that the impact performance for conventional vehicles has been shown, we will focus on the performance for quadricycles and minicars. The literature on the impact crashworthiness of minicars has been mostly written relatively recently and in all events is very scarce. One of the most complete references is the study by Hardy [12], a European study of L category vehicles unladen mass under kg or kg and whether they could meet the same regulatory requirements as M1 cars conventional cars.

The study shows wide disparity between the results of frontal-impact tests for the quadricycles reviewed, and indicates that no current quadricycle would comply with M1 category safety requirements, which suggests that the evolution of safety in quadricycles still has a long way to go.

Mizuno [2] produced a work on passive safety for minicars, which clearly states that their security is less than that of a conventional vehicle due to the technological challenge of their small size and mass.
