A velocity analysis was also performed to determine the angular velocity of the output nozzle with respect to the rotation angle of the nozzle.
Simulation Conclusions
As seen in the figures above, the sprinkler successfully achieves the four distinct sweep ranges. It is noted that there are some slight discrepancies between the left and right side sweeps. The full range sweep is likewise biased towards the right. However, for the intended application, the accuracy of the ranges is more than sufficient.
Also, the velocity analysis suggests there is further nonuniformities in the water distribution. It is particularly noticeable in the full sweep, where the water nozzle travels much quicker through one phase of the right side portion, possibly resulting in less water distributed to that portion of the yard.
SolidWorks Modeling
The following animations demonstrate the motion of the sprinkler with the four dial settings addressed in the MATLAB simulation to verify the resulting sweeps.
