Assembly planning with automated retrieval of assembly sequences from CAD model information

Purpose – The purpose of this paper is to define an approach to extract the liaison graph from a 3D CAD model and analyze a method to find at least a feasible assembly sequence for the product. The method could be useful to search the optimal sequence of assembling for a product, by comparing different sequences extracted in automatic mode from a 3D CAD model.Design/methodology/approach – The method proposed analyzes the liaison graph extracted, in order to obtain the possible assembly sequences for the product under study. The extraction of the sequences is based on some attributes and parameters of the graph.Findings – By means of the method proposed it is possible to obtain in automatic mode the liaison graph of an assembly 3D CAD model. Moreover, the study of the graph obtained allows the definition of all the assembly sequences for the product. Finally, it is possible to analyse the sequences found to select the optimal sequence.Research limitations/implications – The major limitation of the approach...

Advances and trends of head-up and head-down display systems in automobiles

Currently, in the automotive industry the interaction between drivers and Augmented Reality (AR) systems is a subject of analysis, especially the identification of advantages and risks that this kind of interaction represents. Consequently, this paper attempts to put in evidence the potential applications of Head-Up (Display (HUD) and Head-Down Display (HDD) systems in automotive vehicles, showing applications and trends under study. In general, automotive advances related to AR devices suggest the partial integration of the HUD and HDD in automobiles; however, the right way to do it is still a moot point.

General implications of HUD systems applied to automobile industries

This article has the purpose to analyze, based on the current technology, the factors that have been implemented in HUD systems, with the purpose to establish which its functions are and which are the advantages and disadvantages of these systems, in order to compare their relevance at the moment the system is implemented in an automobile. To fulfill this objective an optical and perception analysis was proposed through an instrumental set up, with common characteristics to any automobile, making possible the implementation of a large amount of theoretical and practical considerations. Finally, some recommendations, considerations and conclusions were made, all focused in a proposal of the way that that these systems can be approached.This article has the purpose to analyze, based on the current technology, the factors that have been implemented in HUD systems, with the purpose to establish which its functions are and which are the advantages and disadvantages of these systems, in order to compare their relevance at the moment the system is implemented in an automobile.

Head-up and head-down displays integration in automobiles

In automotive industry, the dashboard has been ergonomically developed in order to keep the driver focused on the horizon while driving, but the possibility to access external electronic devices constraints the driver to turn away his face, generating dangerous situations in spite of the short periods of time. Therefore, this work explores the integration of Head-Up Displays and Head-Down Displays in automobiles, proposing configurations that give to drivers the facility to driving focused. In this way, some of the main ergonomic comments about those configurations are proposed; and also, some technical comments regarding the implemented arrangements are given.

Design Process of a Master Controller for Electric Omnidirectional Platforms

The need vehicles able to move or park easily in narrow or cluttered halls, along with the progress in matter of motors, batteries and controllers applied to electric vehicles has supported the development of electric omnidirectional vehicles, in robotics, industrial and health fields.The solutions currently found in the market generally integrate all the electrical/mechanical components and do not offer an option of a master controller compatible with different omnidirectional platforms.A master controller for electric omnidirectional platforms adaptable to a wide range of usage conditions and mechanical power requirements, would be an interesting component for design purposes at academic level, where engineering students could understand how design variables are related to the component selection.This article presents the design process of a master controller for this kind of vehicles and the procedure for determining its parameters and the specifications for electric motors required on different platforms that will have different mechanical power requirements and use conditions. First, specific characteristic for a general platform have been defined, the kinematic behavior has been characterized and next, a simulation model has been configured and tested with a real platform in order to identify the real behavior or the master controller.
