  • Optimization of a Motorcycle Wheel Rim Using CAD and CAE Software's
    © 2019 JETIR April 2019, Volume 6, Issue 4 www.jetir.org (ISSN-2349-5162) Optimization of a Motorcycle Wheel Rim Using CAD and CAE Software’s Deshabhakt Gavali#1, Harshwardhan Dhumal#2, Niranjan Dindore#3,Parag Betgeri#4, P.H. Lokhande#5 #Department of Mechanical Engineering, Sinhgad College of Engineering, SPPU, Pune-41. Abstract - Wheel Rims form a vital part of two wheeler vehicles. There are two main types of motorcycle rims, namely, Solid Wheels and Spoked Wheels. Solid wheels are the ones in which both the rim and the spokes are manufactured from the same material. While Spoked wheels are the ones in which the motorcycle rim is laced with a number of high tension spokes. This project mainly deals with the optimization of the spoked wheel rim with respect to its weight. The design of the rim is created in a suitable CAD software while, a CAE software is used for analysing the rims for critical conditions. Loading conditions like tyre pressure, radial load and bending load are simulated during the finite element analysis of the component. The geometry of the wheel is optimized until satisfactory results of stress and displacements are obtained. This optimization includes varying the number of spokes and removal of material from the spokes and hub area. ETRTO manual and AIS 073 (Part 2), these standards are referred during the design and analysis stage. Four different models are analysed and compared with each other. The fully optimized model is found to be ’23.587 %’ lighter than the basic design. While it is also found to be safe in all the testing conditions.

  • Modelling and Analysis of a Motorcycle Wheel Rim
    Int. J. Mech. Eng. & Rob. Res. 2013 Saurabh M Paropate and Sameer J Deshmukh, 2013 ISSN 2278 – 0149 www.ijmerr.com Vol. 2, No. 3, July 2013 © 2013 IJMERR. All Rights Reserved Research Paper MODELLING AND ANALYSIS OF A MOTORCYCLE WHEEL RIM Saurabh M Paropate1* and Sameer J Deshmukh1 *Corresponding Author: Saurabh M Paropate, [email protected] Alloy wheels are automobile wheels which are made from an alloy of aluminum or magnesium Metals or sometimes a mixture of both. Alloy wheels differ from steel wheels because Of their lighter weight, which improves the driving and handling of the motorcycle. Alloy wheels made up of composite materials will reduce the unstrung weight of a vehicle compared to one fitted with standard aluminum alloy wheels. The benefit of reduced unstrung weight is more precise handling and reduction in fuel consumption. Alloy is an excellent conductor of heat, improving heat dissipation from the Brakes, reducing the risk of brake failure. At present Motor cycle wheels are made of Aluminum Alloys. In this project, Aluminum alloy are comparing with other Alloy and composite materials. In this project a parametric model is designed for Alloy wheel used in two wheelers from existing model. Wheel rim is that part of an automotive where it undergoes static and fatigue loads because it traverses on a lot of roads. This develops heavy stresses in the rim and thus it is necessary to determine the critical stress point and shear stress. For modal analysis, the model has to be built, loads are applied and solutions are obtained. Motorcycle model is Bajaj pulsar 150 cc.

  • Fit and Adjust a Sidecar on Your Motorcycle; Three-Wheeling
    How to Fit and Adjust a Sidecar on your Motorcycle; Three-wheeling. D. A. Hobbs About the author Daryl Hobbs has been a qualified motorcycle mechanic for over twenty years. During that time he has patched, tuned, fixed, repaired, reconditioned and restored over 70 makes of motorcycle – of course this number has been assisted by owning over 20 makes. Occasionally he would buy one just because he hadn’t worked on that make or model. As a mechanic, accurate and useful information has always been important and the one area that doesn’t seem to have been catered for that well is information on fitting and adjusting sidecars. The authors baptism into the world of sidecars was attaching a second had box to a Russian made Ural. Aware that he would have to readjust just about everything; the adjustments were left a little loose on ride number one. Unfortunately the first left hand corner was in front of a pub with the usual company assembled on the front verandah. The sidecar, realising there were spectators, took a bow (toward the ground) that veered the outfit into the weeds on the wrong side of the road. If you own an outfit, tighten everything. The second outfit was a safer bet having been securely attached for over 30 years, it was a BSA M21 road painters outfit and very good indeed. The sidecar frame had comparable springing to the bike (not much), a comparable third motorcycle wheel that provides a good rolling and steering ability; you just had to leave a little earlier than everyone else to get places.

ABSTRACT suspension. Wheels, and anything directly connected to Spoke is one of some number of rods radiating from them, are considered to be unsprung mass. Traditionally the center of a wheel connecting the hub with the motorcycles used wire-spoked wheels with inner tubes round traction surface. The term originally referred to and pneumatic tyres [1]. Although cast wheels were first portions of a log which had been split lengthwise into used on a motorcycle in 1927, it would not be until the four or six sections. The radial members of a wagon 1970s that mainstream manufacturers would start to wheel were made by carving a spoke into their finished introduce cast wheels on their road going motorcycles. shape. Eventually, the term spoke was more commonly Spoked wheels are usually made using steel spokes with applied to the finished product of the wheelwright's steel or aluminium rims. Cast wheels are predominantly work, than to the materials he used. made from an aluminium-alloy, but can also be made from more-exotic materials, such as magnesium content A double control forming technology of motorcycle alloy or carbon fibre [2]. wheel was firstly developed to form the complex parts with high mechanical properties.
