Last quarter I finished building the model of the oscillation period of the mechanical logic in one single snap-through motion. This week I studied the periodic motion of the system and found that as the oscillation becomes stable, the oscillation period tends to decrease over time before converging to a limit, which is the real oscillation period in the long run. This is due to the fact that the temperature of the actuators cannot decrease to room temperature once it has heated up. Attached is a plot of the temperature of the two actuators in the long run. The picture should be self-explanatory--the temperature of the actuators stays at a temperature slightly higher than the room temperature in the long run.
