Vibration vehicle models provide a great opportunity to integrate vehicle-based vibrations into a mechanical engineering vibrations course. This project works on a multiple-degree-of-freedom (MDOF) including the pitch and bounce of the vehicle body mounting on a suspension system. The approach utilizes differential equation (DE) based mathematical modelling to solve speedbump induced vibration. The problem involves a half-car approach to a vehicle’s response when subject to a speed bump, or a sudden impulse load upon the model. These responses are captured and analyzed on pitch and bounce of the model at the center-of-gravity of the model. Finite element analysis (FEA) will be used in this project.

Students need be familiar with planar kinematic and planar kinetic analysis of rigid bodies, Laplace transform and inverse Laplace transform, and a knowledge of fundamental concepts in vibration analysis. It is suggested that each group is composed of three students.  It will take students 5 weeks to complete this project, including their in-class oral presentations.
