Flexible Wheel Chair
GRD Journals- Global Research and Development Journal for Engineering | Volume 1 | Issue 8 | July 2016 ISSN: 2455-5703 Flexible Wheel Chair Mahantesh Tanodi Department of Mechanical Engineering Hirasugar Institute of Technology, Nidasoshi, Karnataka (India) Sujata Huddar S. B. Yapalaparvi Department of Electrical and Electronics Engineering Department of Mechanical Engineering Hirasugar Institute of Technology, Nidasoshi, Karnataka Hirasugar Institute of Technology, Nidasoshi, Karnataka (India) (India) Abstract The wheelchair is one of the most commonly used assistive devices for enhancing personal mobility, which is a precondition for enjoying human rights and living in dignity and assists people with disabilities to become more productive members of their communities. For many people, an appropriate, well-designed and well-fitted wheelchair can be the first step towards inclusion and participation in society. When the need is not met, people with disabilities are isolated and do not have access to the same opportunities as others within their own communities. Providing wheelchairs that are fit for the purpose not only enhances mobility but begins a process of opening up a world of education, work and social life [1]. The development of national policies and increased training opportunities in the design, production and supply of wheelchairs are essential next steps. Every human being need to move from one place another to fulfill his requirements and to accomplish that requirements he will travel from one place to another place by walking which is a basic medium of transportation. But it is exceptional in case of physically disables (Persons don’t have both legs). In order to support and help such a person’s we designed a special manually lever operated wheel chair. -

Friction-Producing Mechanisms of a Bicycle Chain
Friction-Producing Mechanisms of a Bicycle Chain _ Effectiveness of Chain Lubricants for Reducing Frictional Losses Copyright ©2014 Friction Facts, LLC rev 5-13-14 Overview The friction-producing mechanisms of a bicycle chain moving through a derailleur-style drivetrain are unique and relatively complex. These friction- producing mechanisms arise from friction created in individual links, which are subjected to multiple regions of both high and low pressure, reciprocating sliding forces, and stiction. As such, testing methods for chain efficiency and chain lubricants must address these complex mechanisms. This paper explores the details of how friction is created in a bicycle chain in a modern-derailleur style drivetrain, the role of chain lubricants to minimize friction in a chain, and the limitations of commonly-used friction test methods. This paper also suggests a testing process to analyze the efficiency of a chain and lubricant in a manner specifically relevant to chain friction-producing mechanisms. Friction-Producing Mechanisms of a Chain From a simplified standpoint, the friction created (wasted energy) by a roller chain is generally proportional to: [chain tension] x [sine of lateral deflection] x [link articulation angle at a given engagement or disengagement point] x [number of link articulations per unit time at that point] x [total engagement and disengagement points in the complete drivetrain]. This basic formula has been demonstrated by multiple drivetrain studies and, more recently, by tests performed by Friction Facts. Essentially, friction is created each time an individual link, under a finite level of tension, bends (articulates) as it engages or disengages the teeth of a cog, pulley, or chainring. -

English Summary Walter Ulreich / Wolfgang Wehap Die Geschichte der PUCH-Fahrräder ISBN 978-3-7059-0381-4 22,5 x 26,5 cm, 400 Seiten mit ca. 500 farbigen Abb., Hardcover mit Schutzumschlag, geb., Euro 48,– 1. Beginnings of Bicycle Manufacturing in Austria and Weishaupt Verlag • www.weishaupt.at Styria (1885 – 1889) High wheel bicycles first appeared in Austria-Hungary in 1880. Since they were originally imported from England, they were called “bicycles”. The word Fahrrad came later (though in Swiss German, Velo became the established term). Regular production of high wheel bicycles in Austria-Hungary began in Jan Kohout’s factory for agricultural machines in Smíchov, near Prague, in 1880, following English designs. Kohout’s sons Josef and Petr made a name for themselves and the bicycles as successful racers. Smaller makers before 1885, such as Valentin Wiegele in Korpitsch near Villach, only became known locally. In Vienna, Karl Greger’s Velociped-Fabrik started making high wheel bicycles in 1884 under the brand name ‘Austria’; the annual output seems to have reached 300–400 bicy- cles. In 1896, Greger was mentioned as “the oldest bicycle factory of Austria and one of the largest on the continent”, and as “ founder of the bicycle industry in Austria-Hunga- ry”. At about the same time as Greger, Carl Goldeband and the sewing-machine factory of H. Wagner also began making bicycles in Vienna. In the years from 1885 to 1889, there is good evidence that bicycles were also being made by Mathias Allmer, Josef Benesch und Josef Eigler in Graz, Johann Jax in Linz, Josef Fritsch in Eger (Cheb), Julius Mickerts und Otto Schäffler in Vienna, Nicolaus Heid in Stockerau, near Vienna and G. -
CDIO Worldwide Challenge Meng Group Project
CDIO Worldwide Challenge MEng Group Project Group J Gareth Deering Jorge Guadalupe Fernández Gemma McCallion Andrew McGregor Calum Middleton Sabrina Ralph Website URL – http://xn--y-2fa.no/sab/#future Abstract The 2015 CDIO (Conceive, Design, Implement, Operate) challenge called for the design and build of a folding bicycle that was to be shown and competed at the CDIO Regional Competition on 2nd May 2015. The bike had to be of a lightweight and innovative design that could be folded to a size that would allow city commuters to use it with ease. The first stage of the project was to research the existing market and find a gap that could be filled. It was found that there is a lack of electrically assisted folding bicycles with 20” wheels. Using this information, a number of different concepts were generated and using Pugh’s Total Design process, a final design was found. This design included the desirable electrical assistance as well as a unique ‘slide and fold’ system for folding that allowed for a small folded size. From here, Solidworks and ANSYS were used to bring the design to life and allowed a functioning prototype to be manufactured. Following testing to ensure ANSYS was accurate; this prototype will be taken to the CDIO Regional Competition. i Acknowledgements The group would like to acknowledge the following people for their help during the project. Professor Jim Boyle for his continuous help and support throughout the project. Mr Steven Black and Mr Andrew Irvine for his invaluable help during the building phase. Mr Jim Docherty for the help in ordering all of the components and materials needed to build the bike. -
