Generation of time domain torque signal
Now, in order to simulate this condition in the form of
resisting torque acting on the camshaft, we will have to
convert the T-θ signal obtained earlier into T-time signal.
This was carried out using the characteristic engine speed of
5000 rpm. At this particular engine speed, the corresponding
cam speed would be 2500 rpm (or 41.67 Hz). Based on this
speed the previously calculated torque oscillation curve can
now be converted into a Torque vs. time signal which is
induced in the cam at 2500 rpm. This can be done by
repeating the single revolution signal by the rpm of the cam.
A segment from the Torque - time signal obtained hence
obtained has been shown below:
