Design of a tubular chassis for a kartcross

Abstract

The objective of this project is to establish a method of calculation for designing a tubular chassis of a kart-cross 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 Formula SAE/Student Car, Kart-Cross or NASCAR. 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. 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 tubular 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 vehicle, that, behave properly and be as light as possible. One of its most immediate applications is to assist in the design of a competition car Formula SAE / Student and Kartcross racing, which are used chassis tubular. Nowadays, in the world of automobile 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 a vehicle, big teams don’t care about the money, and they care about the weight and strength of the vehicle. In this project the desired final solution would be a combination of the 3 previous solutions.
