Stress Analysis of Foot Poles

Stress analysis was carried out for the foot poles, modelling the quadpod centre as a built in joint and the tube as a beam. The load was considered as acting upwards from the floor, as it would in a reaction force. The weight of the part itself was considered negligible.

Deflection was calculated first:

Which comes out at 0.5mm and will not affect the performance of the part.

Then max stress:

Which shows it will not fail.

Stress analysis of Top Beam

The top beam was analysed to find the maximum deflection and maximum stress, as shown below.

I = Second Moment of Area and y = distance between load and COM of beam.

Yield Stress is 503 MPa, so the beam will not permanently deform under load

In this case y represents deflection.

This small amount of deflection will not affect the operation of the crane.
