In this project we went off a basis of a frame (firewall) and made sure that everything was mounted right. Along came with it some constraints. These constraints were based on making sure the firewall was grounded and was a stable part for the frame. This made us make sure we had fixed constraints. This structure needed to be able to support the force of a 250 lb engine. Meaning this was attached to the three points indicated on the frame. This structure needed to be tested on a -3G and a 6G, this simulated the exaggerated weight of the engine in change of acceleration or altitude. These structural members had to be 1 1/2 in. ANSI pipe. Then making sure the frame members were trimmed and mitered right.
Procedure
In order to get to this project we did several frame generator tutorials. In these tutorials we learned how to use the simulator to test the frame. We also learned how to place structural members (frames), miter, trim to frame, trim and extend, lengthen, and notch. So when we came to this project we could use those skills learned and apply them to this. We also did materials explorations to find out which materials would be the best to use in certain situations. As in weight, strength, and cost all applied to looking for the best material. The engine mount original was a file given to us and we needed to finish it in order for us to test it in the simulation. As we got this model we made frame poles where the sketches for them were and made sure the poles were trimmed and mitered to the frame so that it was stable. Then we went to a simulation and added our forces. Unfortunately for me it did not work, but I do know when having a 250 lb engine attached and at a -3G we would then get -250 lbs for all three of the attachments on the frame. Then for 6G we would get 500 lbs for each of the attachments.
Solution
I was unable to complete my simulation as from the picture above. Although I can make an assumption that this would be a good frame to work with, because it looked like a stable design. That is about as much as I can say without seeing actual simulation results.
Conclusion
In this project I learned not everything goes as planned when doing projects like this and that you have to learn to adapt sometimes, but also that to work efficiently it's better to ask for help then be doing it wrong. I knew how to miter and trim but it enhanced my understanding of the concepts. I believe the frame generator can be useful when used properly and done correctly (or even if it worked). Otherwise there is no point if you not being specific, because then you are not getting the answers you want to see or hear.
