What software do you guys all use to do the engineering pics and fea analysis ?
Can you get it online?
Read back here at the very bottom
Inventor Professional and Solidworks will allow you to do FEA but more often than not if you don't know exactly what you are doing it can screw you big time. Actually in these parts I would not worry at all as the weight load is minimal and when a crash occurs the loads are so high you can kiss the tower goodbuy
... For example Laia's tower in this dakar broke and had to carry it in her back swapping it between her teamate because it was too heavy
... Of course the load has What I am interested in at the moment as far as the Towers is concerned is how to make them collapse if they get hit by the rider, much like AntiPaul did with his first design.
That was a very nice feature. As far as the other equipment is concerned you have to make them completely
bulletproof. I would prefer to add 200 grams on my roadbook and make sure that is stronger that making it a featherlight unit that gets destroyed with a light touch. You know what I mean...
The subject tha Paul started with an FEA program that will give you hints about the shape, I remeber Designspace from ANSYS which would automatically remove material from the structure. Material that did not do anything as far as the loads and the supports is concerned. You would choose the percentage reduction and it would try and achieve that. Anyways... Back into the Towers ...
@ Tileman, indeed it may be easier to achieve everything with one piece in the middle. That is a great idea. Two parts will always be better as far a weight/torsional stiffness is concerned. Think of I-beams etc. I like the simplicity of it so go forward and get some pics when ready !!
@ Gany, nice ! I always like people trying new things, let us know the stability of this thing. If you push it sideways, does it give way and spring back ? Vibrations? I was thinking about desert and in general summer temps. From what I have seen the PE pipes that I have used before they get soft if you leave them in the sun and then they retain that shape when it gets cold. I am wondering if this will get softer after racing in the sun. Thoughts ?
Keep it coming boys !
