Hi all,
I'm currently designing a housing for a camera and omnidirectional mirror for a robot. The housing is connected to the robot through a rod of about 25mm diameter.
...{...}... (housing)
...|... (rod)
...(___)... (robot base)
I'm trying to compute the deflection in the rod when the robot accelerates (or deccelerates) at its max of 1m/s^2 but not sure how I'd go about it.
Conceptually, when the robot is at rest the rod would act as a column with a concentric load. Once the robot accelerates, the inertia of the rod and housing would cause it to want to stay, hence causing the deflection. Once it begins to deflect, the housing becomes an eccentric load and causes the rod to deflect more. The dimension of the rod is fixed so I have to ensure the housing is light enough to minimise deflection and vibration.
At this stage I'm looking at doing a rough FEA simulation and seeing what numbers it spits out but how would you go about solving such a problem analytically?
