  • Motorcycle Rear Suspension
    Project Number: RD4-ABCK Motorcycle Rear Suspension A MAJOR QUALIFYING PROJECT REPORT SUBMITTED TO THE FACULTY OF WORCESTER POLYTECHNIC INSTITUTE IN PARTIAL FULFILMENT OF THE REQUIREMENTS FOR THE DEGREE OF BACHELOR OF SCIENCE BY JACOB BRYANT ALLYSA GRANT ZACHARY WALSH DATE SUBMITTED: 26 April 2018 REPORT SUBMITTED TO: Professor Robert Daniello Worcester Polytechnic Institute Abstract Motorcycle suspension is critical to ensuring both safety and comfort while riding. In recent years, older Honda CB motorcycles have become increasingly popular. While the demand has increased, the outdated suspension technology has remained the same. In order to give these classic motorcycles the safety and comfort of modern bikes, we designed, analyzed and built a modular suspension system. This system replaces the old twin-shock rear suspension with a mono- shock design that utilizes an off-the-shelf shock absorber from a modern sport bike. By using this modern shock technology combined with a mechanical linkage design, we were able to create a system that greatly improved the progressiveness and travel of the rear suspension. Acknowledgements The success of our project has been the result of many individuals over the course of the past eight months, and it is our privilege to recognize and thank these individuals for their unwavering help and support throughout this process. First and foremost, we would like to thank our Worcester Polytechnic Institute advisor, Professor Robert Daniello for his guidance throughout this project. His comments and constructive criticism regarding our design and manufacturing strategies were crucial for us in realizing our product. We would also like to thank two other groups at WPI: The Mechanical Engineering department at WPI and the Lab Staff in Washburn Shops.

  • Design and Structural Analysis of a Front Single-Sided Swingarm for an Electric Three-Wheel Motorcycle
    applied sciences Article Design and Structural Analysis of a Front Single-Sided Swingarm for an Electric Three-Wheel Motorcycle Polychronis Spanoudakis * , Evangelos Christenas and Nikolaos C. Tsourveloudis School of Production Engineering & Management, Technical University of Crete, 73100 Chania, Greece; [email protected] (E.C.); [email protected] (N.C.T.) * Correspondence: [email protected] Received: 31 July 2020; Accepted: 27 August 2020; Published: 1 September 2020 Abstract: This study focuses on the structural analysis of the front single-sided swingarm of a new three-wheel electric motorcycle, recently designed to meet the challenges of the vehicle electrification era. The primary target is to develop a swingarm capable of withstanding the forces applied during motorcycle’s operation and, at the same time, to be as lightweight as possible. Different scenarios of force loadings are considered and emphasis is given to braking forces in emergency braking conditions where higher loads are applied to the front wheels of the vehicle. A dedicated Computer Aided Engineering (CAE) software is used for the structural evaluation of different swingarm designs, through a series of finite element analysis simulations. A topology optimization procedure is also implemented to assist the redesign effort and reduce the weight of the final design. Simulation results in the worst-case loading conditions, indicate strongly that the proposed structure is effective and promising for actual prototyping. A direct comparison of results for the initial and final swingarm design revealed that a 23.2% weight reduction was achieved. Keywords: swingarm; single-sided; Finite Elements Analysis (FEA); three-wheel motorcycle; topology optimization 1.

  • Design and Experimental Validation of a Carbon Fibre Swingarm Test Rig
    DESIGN AND EXPERIMENTAL VALIDATION OF A CARBON FIBRE SWINGARM TEST RIG Reno Kocheappen Chacko A research report submitted to the Faculty of Engineering and the Built Environment, of the University of the Witwatersrand, in partial fulfilment of the requirements for the degree of Master of Science in Engineering March 2013 Declaration I declare that this research report is my own unaided work. It is being submitted to the Degree of Master of Science to the University of the Witwatersrand, Johannesburg. It has not been submitted before for any degree or examination to any other University. …………………………………………………………………………… (Signature of Candidate) ……….. day of …………….., …………… i Abstract The swingarm of a motorcycle is an important component of its suspension. In order to test the durability of swingarms, a dedicated test rig was designed and realized. The test rig was designed to load the swingarm in the same way the swingarm is loaded on the test track. The research report structure is as follows: relevant literature related to automotive component testing, current swingarm test rig models and composite swingarms were outlined. The Leyni bench, a rig specifically developed by Ducati to test swingarm reliability was shown to be effective but lacked the ability to apply variable loads. The objective of this research was to design and experimentally validate a swingarm test rig to evaluate swingarm performance at different loads. The methodology, the components of the test rig and the instrumentation required to achieve the objectives of the research were presented. The elastic modulus of the carbon fibre swingarm material was calculated using classical laminate theory. The strains and stresses within a swingarm during testing were analysed.

Dhariwal2 Sinhgad School of Engineering, Department of Mechanical Engineering, Pune- 411058, Maharashtra, India. [email protected] ------------------------------------------------------ ***-------------------------------------------------- Abstract: - Grand Prix Motorcycle Racing (MotoGP) refers to the sport class of motorcycle used in motorcycle racing events under governing body of FIM (Fédération Internationale de Motocyclisme). Motorcycles having power of 260 bhp and that can go up to 355 kmph are used in this event. During high speed-cornering, the motorcycle is subjected to extreme loads; hence every component of motorcycle must be designed precisely and analysed in order to endure the extreme loading conditions. A swingarm allows connecting the rear wheel with the chassis which gives more space for rear suspension and while pivoting vertically, it absorbs bumps coming on the road. The focus of this research is to redesign a swingarm for MotoGP standard motorcycle by application of multiaxial forces and using manual Shape Optimization technique to reduce overall weight of the motorcycle. Since weight is the factor of consideration, Aluminium 7075 T6 material is selected for the swingarm as its structural rigidity and strength to weight ratio is most ideal for application.
