These articles have been peer-reviewed and accepted for publication but are pending final changes, are not yet published and may not appear here in their final order of publication until they are assigned to issues. Therefore, the content conforms to our standards but the presentation (e.g. typesetting and proof-reading) is not necessarily up to the Inderscience standard. Additionally, titles, authors, abstracts and keywords may change before publication. Articles will not be published until the final proofs are validated by their authors.

  • An Intelligent Computer-based Framework for Integrating Emotions and Aerodynamics in Sportsbike Design   Order a copy of this article
    by Philip Farrugia, James Mamo, Tonio Sant 
    Abstract: In today\'s extremely competitive market, the features and specifications of competing products are very close. Therefore, how the design of the product connects with the consumer on an emotional level, is critical. Due to the importance of creating products which deliver emotional satisfaction to the user, a Design for Emotion (DFe) approach must be adopted by product design engineers. At the same time, design engineers have to apply fundamental principles to enhance the performance of complex artefacts. This is the case in the design of sportsbikes, where design engineers have to ensure that the motorcycle is aerodynamically optimised as possible, yet it is aesthetically pleasing. A sportsbike cannot be designed based on aesthetics only, but rather on a balance between aesthetics and aerodynamic performance, as the design of the outer body itself is what ultimately affects the drag and lift properties. Within this context, a framework for an intelligent computer-based design support system was developed aimed at supporting designers to take emotions and aerodynamics when developing sportsbikes. A proof of concept computer-based tool was implemented and evaluated. Qualitative results gathered from an evaluation conducted with eight practicing product development stakeholders, provide a degree of evidence that the proposed framework is useful in designing sportsbikes with more emotional value and enhanced aerodynamic characteristics.

  • Investigation on Glass- Epoxy Composite Drive Shaft for Light Motor Vehicle   Order a copy of this article
    by Rajaram Shinde, Suresh Sawant 
    Abstract: The composite material is excellent material where high strength to weight ratio is desirable. It has a wide variety of applications in the aeronautical and automotive field. One of the great features of the composite material is that it can be designed as per the strength requirement of applications.rn A drive shaft is a rotating shaft that transmits power from the engine to the differential gear of a rear wheel drive vehicles. Generally, an alloy steel drive shaft is used in automotive. To improve the fuel economy by reducing inertia loads, steel needs to be replaced by strong and light weight material. In this research, glass epoxy composite drive shaft is successfully designed for light motor vehicle. The replacement of conventional steel by composite material, resulted in 77% of weight reduction of drive shaft. The designed glass epoxy composite drive shaft is investigated experimentally for the torsional strength, natural frequency and critical speed. Results obtained are compared with steel drive shaft. The developed composite shaft had proved to be best alternative to conventional steel shaft.
    Keywords: Composite driveshaft; torsional strength; natural frequency; weight minimization.

  • Mathematical Modelling of Pressure Distribution along the Die of a Biomass Briquetting Machine   Order a copy of this article
    by Joseph Orisaleye, Sunday Ojolo 
    Abstract: Screw extruder briquetting machines produce high quality solid fuels from raw biomass. However, problems encountered have been attributed to poor design due to the trial-and-error approach often used in selecting design parameters or geometry of the machine. This necessitates the development of theoretical models for the purpose of developing efficient machines. The briquetting die is critical since it determines the quality of biomass briquettes. In this study, mathematical models were developed to study pressure distribution along the briquetting die. Mathematical models were developed by using the hot extrusion scheme and assuming a plug flow. Parametric analysis to determine the effects of design variables on die pressure distribution was carried out by simulation using developed mathematical models. Results showed that pressure along the die entry decreases rapidly with high yield strength of compacted biomass and with increased friction coefficient at the briquetting die interface. Pressure along the die decreases rapidly for increased friction coefficient at the briquetting die interface. Parameters resulting in rapid pressure decrease along the briquetting die length would result in increased die pressure at the end of the screw extruder. The developed mathematical models and the results obtained could significantly contribute to design of briquetting dies.
    Keywords: Biomass densification; screw extruder briquetting machine; pressure distribution; die pressure; mathematical model.
