A Design Methodology for Maintainability of Automotive Components in Virtual Environment
No full textThe present paper deals with the problem of the ergonomics of maintenance tasks in automotive industry pursuing the following aims: analysis of Human Modelling Software and their use in automotive task analysis; development of a design methodology (named EDIVE)for maintainability of the component parts of a car engine compartment in a virtual environment and, finally, the individuation of an optimal postural sequence to disassemble such components, taking into account human factors. In the paper the authors show how to integrate DMU tools and Digital Human Modelling software in order to individuate the optimal postural sequence of an operator that have to disassemble a component part of a car engine compartment
Stochastic Design Improvment of an impact absorber
No full textThis work deals with a numerical investigation which has been carried out to study the crash behaviour of an automotive substructure located in the rear part of a vehicle, using a new stochastic methodology, Stochastic Design Improvement (SDI). Fundamentally, an iter-ative Monte Carlo simulation procedure was executed, whose trials consisted of deterministic numerical analyses based on explicit fnite element methodologies.
The SDI procedure has been applied to reduce of a given amount the maximum displace-ment of a rigid barrier impacting against the rear substructure of a vehicle in a particular crash test.
The procedure allowed an e±cient solution to the considered problem and the fnal results were validated through experimental tests
