Effects of Camber Angle on a Sports Car Steering Response

Introduction

This project is a collaboration of MSc Mechanical Engineering students at TU Delft, including Varun Kotian, Nikhil Nagendra, Shantanu Shivankar, Yen-Lin Wu, and a master student at KTH, Filip Berggren. This is a repository for the final project of the course Vehicle Dynamics (ME41100) at TU Delft. This report studies the driving experience of different camber angles (-10 deg to 10 deg) on a sports car in 3 different driving scenarios:

1. a steady-state turn,
2. a step steering response,
3. a sinusoidal steering response.

The simulation is conducted on IPG CarMaker software, whose results (in .csv) are uploaded and sorted in folders.

Abstract

This report studies the driving experience of different camber angles on a sports car in different driving scenarios. The camber angle is varied between -10 to 10 degrees and the tests are performed in three different driving scenarios:

1. a constant turn,
2. a step steer response,
3. a sinusoidal steer response.

To evaluate the driving experience, the following performance indicators are analyzed:

1. yaw velocity,
2. yaw velocity response gain,
3. yaw velocity overshoot ratio,
4. lateral acceleration response time,
5. lateral acceleration overshoot.

The study concludes that a more negative camber angle results in a sportier driver experience but also yields a more oversteered behaviour.
