It is one of the most critical components in an automotive. Upright is the part that is connected with suspension arms, the hub brake caliper mounting and also the steering tie rod in formula vehicle. For Formula vehicle the goal is to design a light weight, yet sufficiently strong upright. All the loads reacted by the wheels are transmitted to the chassis through the ‘A’ arms indirectly from the upright. Generally the nature of the loads is bending. Different materials are used for manufacturing upright components like Aluminum alloys Al 7075-T6 for light weight applications, Alalloy 6061-T6 for moderate weight and moderate cost or steel in case of low cost application. First the upright is design in solid work with respect to the suspension mounting points. The model is meshed using ANSYS and analyzed based on the loads calculated using analytical method using formulae for various manures possible. Previously manufactured upright of Al-alloy 6061-T6 had weight of 2 kg. In this project, the upright is designed with Al 7075-T6, reducing the weight to 1.17 kg and also sustaining the loads better than the previous design.
