Design of a bicycle frame, Mechanical Engineering

Design of a Bicycle Frame: Figure  depicts a simple bicycle frame, which is to be built of hollow aluminium tubing with outside diameter of 20 mm and wall thickness of 2 mm. The frame is under two loads, F1 and F2, which are the loads transferred from the seat and pedals to the frame, respectively. The frame is fully constrained at point 1 and translational degrees of freedom of points 5 and 6 are constrained in both y and z directions. Use ABAQUS to model the frame and obtain the maximum load (F1) the frame can carry assuming safety factor of 2 and using Von Mises Criterion.

Assumptions:

i.The frame is modeled as a single part.

ii.Use beam elements to model the hollow tube of the frame.

iii. F1 = 3 F2.
