MassSpringDamper
The MassSpringDamper program uses the SA::EulerCromerIntegrator class to simulate a forced mass-spring-damper system.
The mass is chosen to be 1 kg. The damping constant is chosen to be 5 Ns/m. The spring constant is calculated for a frequency of 2 hz. Every 5 seconds, the system is given an impulse of 500 Newtons for 0.005 seconds.
For each numerical integration time-step, the simulation program prints
- time (s)
- position (m)
- velocity (m/s)
to stdout, in Comma Separated Values (CSV) format.
Building & Running the Simulation Program
To compile MassSpringDamper:
$ make
To run it, and generate a CSV file:
$ ./MassSpringDamper > msd.csv
Plotting the Results
The Python script, plot_position.py is provided to plot the results in msd.csv using (Python) matplotlib.
Plot position vs. time as follows:
$ python plot_position.py
