Automobile Suspension System Objective To develop and validate an analytical model for evaluating the suspension systems of heavy vehicles; and to use this model to improve current bus suspension systems. The need Transportation systems are dependent on many technical criteria. In fact, one of the most important criteria is the suspension system. An automobile is not perfect without a proper suspension system. Many suspension systems that are available in the existing technology.

Analysis of the problem and suggested solutions In our project, we will simplify our problem into a one dimensional spring damper system, representing one of the four wheels of the automobile. Please refer to page 3 for a diagram of this damper system. We will first simulate the system without the controller to ensure the system properly functions. Next, we will add the Proportional-Integral-Derivative PID controller: a type of feedback controller whose output is based on the error between some user-defined set point and some measured process variable. Next, we will attempt to code and simulate the response of the system to different inputs. If the results are satisfactory, we will expand the design the system for all four wheels. Else, we will continue to improve the current system to the best of our abilities. Distribution of tasks Ghazala Ghinwa Amina omar Hamza
