Electronic Automatic Transmission for Bicycle Design Document
Electronic Automatic Transmission for Bicycle Design Document Tianqi Liu, Ruijie Qi, and Xingkai Zhou Team 4 ECE 445 – Spring 2018 TA: Hershel Rege 1 Introduction 1.1 Objective Nowadays, an increasing number of people commute by bicycles in US. With the development of technology, bicycles that equipped with the transmission system including chain rings, front derailleur, cassettes, and rear derailleur, are more and more widespread. However, it is a challenging thing for most bikers to decide which is the optimal gear under various circumstances and when to change gear. Thus, electronic automatic transmission for bicycle can satisfy the need of most inexperienced bikers. There are three main advantages to use with automatic transmission system. Firstly, it can make your journey more comfortably. Except for expert bikers, many people cannot select the right gear unconsciously. Moreover, with so many traffic signals and stop signs in the city, bikers have to change gears very frequently to stop and restart. However, with this system equipped in the bicycle, bikers can only think about pedalling. Secondly, electronic automatic gear shifting system can guarantee bikers a safer journey. It is dangerous for a rider to shift gears manually under some specific conditions such as braking, accelerating. Thirdly, bikers can ride more efficiently. With the optimal gear ready, the riders could always paddle at an efficient range of cadence. For those inexperienced riders who choose the wrong gears, they will either paddle too slow which could exhaust themselves quickly or paddle too fast which makes the power delivery inefficiently. Bicycle changes gears by pulling or releasing a metal cable connected to the derailleurs. -

Analytical Model for the Radial Strength and Collapse of The
6th Annual International Cycling Safety Conference 21-22 September 2017, Davis, California, USA Analytical Model for the Radial Strength and Collapse of the Bicycle Wheel Matthew Ford*, Oluwaseyi Balogun# *Department of Mechanical Engineering #Department of Civil & Environmental Engineering Northwestern University Northwestern University 2145 Sheridan Road, Evanston, IL, 60208, USA 2145 Sheridan Road, Evanston, IL, 60208, USA email: [email protected] email: [email protected] Keywords: bicycle wheel, strength, buckling, collapse, crash prevention, finite-element modeling 1 INTRODUCTION The bicycle wheel is a versatile engineering structure which serves many functions including supporting radial and lateral loads, transmitting propulsive torque, and sustaining braking loads. When a wheel is overloaded radially it typically buckles laterally (or “tacos”) which renders the wheel unridable. It is both of theoretical interest and practical importance to develop a theory for the strength—and failure—of the wheel. We analyze the failure mechanisms of tension-spoked wheels using a combination of computational and theoretical approaches. There are two primary failures which both lead to wheel collapse: loss of spoke tension, and lateral buckling of the rim. Designing against either failure mode presents a conflict because increasing spoke tension prevents spokes from going slack, but it also decreases the lateral stiffness of the rim, which is under compression due to the spokes. By analyzing these two modes separately and then equating the critical loads, we develop an expression for the wheel strength which is independent of spoke tension. 2 BUCKLING OF SPOKED WHEELS A bicycle wheel may buckle laterally—or “taco”—due to excessive spoke tension, lateral force, or radial force. -
The Telescope Stand Inspiration for Marcel Duchamp's Bicycle Wheel
Kunstgeschichte. Open Peer Reviewed Journal www.kunstgeschichte-ejournal.net STEPHEN FAWCETT (BALDERTON , NOTTINGHAMSHIRE ) The Telescope Stand Inspiration for Marcel Duchamp’s Bicycle Wheel Readymade Abstract This article is the result of research following on from the author’s previous article on the same subject, ›The Inspiration for Marcel Duchamp’s Bicycle Wheel Readymade‹ written in 2007. In that article the author argued by process of deduction that Duchamp’s Bicycle Wheel was inspired by an improvised telescope stand and was not the product of the artist’s imagination as the artist claimed. This article presents new supporting evidence of a Great War period photograph of an improvised telescope stand made with a bicycle wheel and forks. This article also examines the dating of the first version and construction of the authorised versions of Bicycle Wheel and presents new evidence for the source of the forks component of the 1916 version. <1> Bicycle Wheel is a three-dimensional artwork by French artist Marcel Duchamp (1887-1968). This well-known Readymade exists today in various artist-authorised versions. 1 I have been fortunate to find a Great War era photograph (fig. 1) showing the inverted front forks and wheel of a bicycle being used as a universal type mounting for a telescope, an item of military equipment, exactly as I imagined in my 2007 article. 2 Although this telescope stand does not employ a stool, it nonetheless offers considerable support for my original contention that Duchamp’s Bicycle Wheel was copied from an improvised telescope stand and was not the product of the artist’s imagination as he claimed. -

Material Comparison for a Bicycle Crank Set-Final
Weight Reduction Case Study of a Premium Road Bicycle Crank Arm Set by Implementing Beralcast® 310 By: Sean Sullivan Chris Huskamp, IBC Advanced Alloys Date: March 4, 2013 Overview The crank set is the device responsible for converting the bicycle rider’s human power to rotational mechanical power. The crank set travels in a clockwise motion, propelling the bicycle forward. Figure 1 shows the first 180º of a complete crank rotation along with the corresponding torque curve. 180º was chosen because this represents the “power stroke”, the remaining portion of the crank rotation is the “dead stroke.” The dead stroke refers to the fact that no torque is generated by the crank, assuming pedal straps are not used. The two cranks which make up the complete crank set are 180º out of phase which allows for a continuous transfer of torque. As Figure 1 illustrates, the torque increases to a maximum at 90º and begins decreasing until once again reaching zero at 180º. The torque curve assumes that the rider applies a constant pedal force. In reality, the applied force drops off as the rider’s leg extends and the torque curve does not possess perfect symmetry about the 90º point. Therefore, the first 90º are of specific interest when examining the loading conditions. There are three main loading conditions which the crank undergoes: axial torque (torque transmitted to the bicycle’s wheel), side torque (bending the crank arm out, in, or twisting), and combined torque (combination of side and axial torque). The maximums for these conditions are: 0º for side torque, 45º for combined torque, and 90º for axial torque. -

Calculation of Rear Brake Power and Rear Brake Work During Skidding On
J Sci Cycling.Vol. 8(3), 33-38 DOI : 10.28985/1920.jsc.06 RESEARCH ARTICLE Open Access Calculation of rear brake power and rear brake work during skidding on paved and gravel cycling surfaces Matthew C Miller1, Aden A Tully2, Adam M Miller1, Stephen R Stannard1 and Philip W Fink1 * Abstract The use of a brake power meter at each wheel of a bicycle is a valid means to calculate energy losses due to braking. However, methodology utilizing the torque and angular velocity at each wheel independently are not able to reflect energy lost to braking when the rear wheel is skidding. This study tested the possibility of using the angular velocity of the front wheel, but the torque of the rear brake, to calculate rear brake power. Two cyclists completed 100 braking trials across three days on a mixture of paved and gravel surfaces with a mixture of skidding and non-skidding. The estimated total energy removed from the bicycle-rider system was calculated as the sum of brake work and estimates of drag and rolling resistance. This energy removed from the bicycle-rider system displayed a strong positive relationship with the change in kinetic energy of the bicycle-rider system during braking on paved (r2=0.955; p<0.0001) and gravel surfaces paved (r2=0.702; p<0.0001). There was no difference between these measurements overall (p<0.05), however there is some error of measurement when skidding on gravel. The findings in the present investigation indicate that rear brake work is underestimated when using the angular velocity at the rear wheel during skidding, but that utilising the angular velocity of the front wheel is a valid means of calculating rear brake power.
