Development of an auto rickshaw vehicle suspension

An auto rickshaw is a three wheeled motor vehicle with one front steering wheel. Auto rickshaws are most commonly found in developing countries as they are a very cheap form of transportation due to low price, low maintenance cost, and low operation costs.Auto rickshaws needs to be developed to take the step into the 21-century. Therefore a project was started by Luleå University of Technology where a hybrid auto rickshaw concept was developed in collaboration with TVS Motor Company Ltd.; which is an Indian manufacturer of auto rickshaws.To develop a new product in the modern world one of the most important challenges is safety of the users. As for the automotive industries this challenge has a great importance since the outcome can be devastating. One important category from the safety point of view is the vehicle suspensions, as the suspensions control the movement of the wheels and thus keeping the vehicle on the road.An important factor in developing the new hybrid auto rickshaw was to improve its safety. One way of improving the safety is to improve the suspension which is addressed in this thesis work. Hence a development of the suspension was carried out to analyse if the negative handling characteristics typical for a three wheeled vehicle could be improved in the hybrid auto rickshaw.To save time and money, modern test cycles of the dynamic characteristics are often conducted in software simulations. A commonly used software in the automotive industries is Adams/Car from MSC Software, which is based on multi-body dynamics and motion analysis. Another well used program is Siemens NX which is a CAE software which was mostly used in this thesis. This thesis covers the basics of these two softwares where systems were modelled and simulated to evaluate the suspensions.The goal of this thesis work was to develop a vehicle suspension intended for an auto rickshaw. A variety of different suspension types were investigated and evaluated until two suspension types were chosen; one type for the front and one type for the rear. These suspension types were then simulated and tested in Siemens NX 8.0 in different critical scenarios to gain useful information. The information was then evaluated to draw a conclusion if the developed suspension obtained good performance.The final solution was simulated and partly verified and still work remains to get a full overview of the performance. This thesis covers the first steps in the design process.
