Automotive Suspension Analysis

Aim -

To formulate a multibody representation (using forward dynamic approach) of the MacPherson and Double Wishbone suspension on MATLAB and optimise the spring constant to reduce the amplitude of vibrations felt by passengers

Motivation -

I've always had a fascination with mechanisms. Having been introduced to kinematic and dynamic analysis in my third semester, I was fascinated by the existence of an enormous formal field of study in this very domain. To facilitate learning this beautiful subject beyond the semester, my instructor (of the course) suggested this project.

What I learnt -

Application of MATLAB to model a real world system
Relegating computations to MATLAB and exploiting the computing power at my disposal
An introduction to Multibody Dynamics (through the book Planar Multibody Dynamics, PE Nikravesh)

Progress and Current Status -

Model of MacPherson suspension is ready
Optimisation of spring is pending
Currently shelved

Animation on MATLAB when the wheel goes over bumps (Forward dynamic approach). The purple link represents the chassis of the vehicle. The green link is attached to the wheel.

Rough Timeline -

Project obtained - First week of December
Work started - Primarily last week of December (after the inter IIT tech meet)
Project shelved - First week of March (after the nonlinear normal modes project was undertaken)
