Damped Spring Mass With Dash Pot
Project Statement
I chose to analyze a car's suspension. Only one wheel's system will be considered to simplify calculations. The car will be simulated as running over a constant road surface similar to that of an ideal driving surface. The Fourier series can be represented with proper assumptions.
First a picture to represent the system used in a car.
D = Dash pot (shock absorber)
K = spring
M = mass of 1/4 of the car
To imagine this system accurately we must flip the diagram upside-down and the ground can then be the road and the mass (M) and the force of the car (f) can be in the proper direction. To find the Fourier series the Dash pot (D) will be neglected. The Dash pot will be implemented later to show the effectiveness of the car's suspension to slow the wave motion caused by road surfaces.
Analysis
The equation of motion is to be considered:
