“…In order to communicate with the process subjected to parametric measurements, computer must be equipped with an additional hardware interface device which plays the role of converting input analog signal into output numerical signal on a certain number of bits, based on the analog-to-digital conversion [8,12]. So, the hardware virtual instrument interface should include an analog to digital converter.…”

Current software development directions open up a world of possibilities, especially in the engineering field. Present paper is meant to highlight the advantages and in particular the ease of using virtual instrumentation facilities, with a proper and adequate design and implementation of desired instrument. In this idea we bring into discussion a design for virtual instrument which can be used for data acquisition that can be stored for further simulations according to the needs required by the process in discussion.

“…Belt conveyers have different lengths, are driven by motors with different speed and powers, their gearboxes have different ratio and for each belt conveyor a different type of variable speed drives was used. The functioning of entire process is controlled by means of one PLC [7][8][9][10][11].…”

It is known that main aspect at a belt conveyor functioning is speed control. This issue has a greater impact upon a process when two or more belt conveyers must work together in order to obtain high quality products. In this case we talk about, not only speed controlling, but of another important aspect, synchronization of belt conveyers. Present paper describes a solution designed and implemented for synchronization of two belt conveyers of different lengths. Each belt conveyer is driven by a motor. Each motor works at its own speed drive. The two conveyors are working together in a process of producing anti-slip door mats which are mainly used at inside door, decorative purpose, etc. The proposed solution is using a PLC and two variable speed drivers with different transmission ratio. This solution can be applied in processes which are divided in sub-processes that must work as a production flow.

“…Moreover, making the right selection of the material for a mechanical system considering the environmental aspects is important for the development regarding the functionality of the part with the replace material. In this way, the simulation by finite elements method (FEM) allows static and thermal analysis, and, thus, optimization leading to more reliable parts [22] where the pinion has to endure forces in the teeth due to the curved surface that pushes one against the other to produce the rotary motion [23], and that is the phenomenon that can be replicated with the FEM. In this sense, the research of Chen et al, using computational simulations, proved the importance of mesh performance on modified straight bevel gears, showing that the modifications on tooth end relief and symmetric crowns allows them to avoid the edge effect and alignment errors, hence, reducing the sensitivity of bending and meshing impacts and improving the results of bending fatigue [24] that can be directly associated to the LCA of the gears [24].…”

Multicriteria Decision Making of a Life Cycle Engineered Rack and Pinion System

The automotive industry has been developed over the years to build lighter and more efficient vehicles; however, the manufacturing processes still have an important environmental impact starting from the acquisition of the raw material until the end of its useful life. In this sense, life cycle engineering contributes to solve the environmental issues produced by the traditional manufacturing industry by considering a process that evaluates the technical aspects of the product but also weights the importance of the environmental impact. However, since there are some alternatives that can be considered as suitable for their technical, environmental, or cost qualities, the multicriteria decision methods used as an engineering tool have been useful to balance all the needed criteria in order to make the best selection. In this sense, this research provided an analysis of five materials that could be used in a rack and pinion system and were submitted to a process of life cycle analysis to consider the environmental parameters as part of the criteria to be assessed by the multicriteria decision methods such as entropy, the Technique of Order Preference Similarity method, the complex proportional assessment method, and the multicriteria optimization and compromise solution, leading to the selection of the best material to be considered for a rack and pinion system. In this sense, the process allowed us to conclude that some materials that are useful can be evaluated by multicriteria decision methods regarding the life cycle analysis, contributing to the application of these methods to make a more environmentally responsible material selection for automotive parts. Furthermore, among all the materials, the best suited for the rack and pinion system was the AISI 4340, which was validated by finite elements simulation, showing that the selection was optimal with a maximum stress of 216.14 MPa, a maximum deformation of 0.0081 mm, and a minimum safety factor of 3.56. In this sense, the simulation validated the selection made before, guaranteeing that the methods used are feasible for automotive applications.
