Analysis and design of a motorbike chassis

Abstract

The objective of this project is to establish a method of calculation for designing a chassis of a motorbike in a manner in which can be measured all the parameters that are related to the design to get a chassis as light, strong and economical as possible, taking into account that the time available is limited. It is first necessary to know when you can give as valid a chassis in their resistance. This is essential to know the criteria used by tubular chassis designers in different competitions such as MotoGP or Superbikes. Once you are aware of the limits that must not be exceeded we must decide how it will be done the calculation. The theory of finite elements would be ideal if the geometry was easy to obtain. The idea is not create a final design for manufacturing; it is validating a first design for the construction of a prototype on which if perform the testes that will lead to production. For the purposes of these theories is necessary to make a rough drawing of the chassis. To carry out this approach correctly, it is essential to keep in mind the methods of manufacture which provides a worker when constructing a structure such as this. The usefulness of the project is evident. It is absolutely necessary to know how carry out the calculation of a chassis to design a tough motorbike, that, behave properly and be as light as possible. Nowadays, in the world of motorbike competition, the solution for the construction of a chassis could be: the cheapest one, the lightest one or the most resistant one. A lot of money is being spent on the construction of the motorbikes, big teams don’t care about the money, and they care about the weight and strength of the motorbike. In this project the final solution desired would be a combination of the 3 previous solutions.
