ANSWER THE QUESTION... How can I improve my design if it’s a new design? Why not build one and see how it performs first? Given a static load case, we set out to determine the overall structural integrity of the robot and understand what kind of deflections that the components of the gimbal system would experience given rapidly moving water flows. Since no real load cases existed, as yet, we estimated loads based on the flow of water at 3 m/s around a cylinder:
where Cdrag coefficient is a function of the Reynold’s number – based on empirical research by Achenbach (1968). What we got out of the study were reasonable load estimations and a design we could have confidence in.
