Description
The main goal was to design an engine mount frame for a Lycoming O-300 light aircraft. The firewall must be the grounded part of the frame. Fixed constraints must be used on the seven attachment points. It must support the engine (250 pounds) at the tree points. The structure must be loaded with negative 3g and positive 6g to simulate exaggerated weight due to acceleration and change in altitude. The members must be 1 1/2 ANSI pipe and be mitered or trimmed as necessary.
Procedure
to prepare for this project we researched different materials with varying strength to weight ratios. The tutorial showed us how to use the frame analysis function in inventor. the skeletal of the frame was given to us and we placed the members with the material of our choice. We had to miter joints and trim the members to the faces to prevent the material from poking through.
solution
The testing was to test the deflection of the members when the loads are applied. My design meets the constraints by having all of the joints mitered and trimmed correctly and by using the correct size pipe. For the members I used mild steel because it is very strong and would support the weight.
conclusion
I learned how to build and test structures for there ability to handle force loads.
I do believe that it is helpful to engineers because it can simulate the work loads without using real materials, saving money and time.
