Well the dream begins. I'm embarking on the building of a 914 project. Here is the candidate. Bought a roller from LA area. Looks like its not going to be too much rust. Firsts thing will be to strip it. Taking front fenders and rear quarters off. Then sending to Cal Blast for media blasting. I look forward to the knowledge that I can gain from fellow enthusiasts. Plan on taking a lot of pics Stay tuned......

2g Lateral Load at rear yields a 1/16" lateral deflection
3g Couple at rear yields a 0.114 vertical deflection 3g Couple at front yields a 0.10" vertical deflection 2g Lateral in front yields a WHOPPING 0.70" lateral defelction. This is the worst case. It makes sense too in that the hole where the engine is allows this deflection. I'll have to fix that somehow. I have to wait until the motor is in to add a removable cross brace or just live with it. We will see. |

(IMG:style_emoticons/default/beerchug.gif) If you have time it might be interesting to run a case with a bunch of tubes connecting the rough engine mount locations into one node. At least it'd give you some idea of how much deflection the engine stops (assuming it's not super softly mounted). I bet with an "engine" surrogate in there you'd get a lot of the 0.70" back without making any other changes. Adding a bolt-on stressed panel under the engine (could double as a belly pan for aero) would bring back a bunch of stiffness too. Two pure curiosity questions...How much does it weigh? What software are you using for FEA? |
