We are a group of students working on a project and in our school they don't teach us solidworks, so we have to learn all of this stuff on our own. I have two problems that I will list here:
We have two different designs so far for the telescope, the first one is a Hexapod platform, and the second one is a Tensegrity structure. Please look at the two links below:
Our problem with the Hexapod: As you can see the upper ring is holding the secondary mirror at the center, and the ring is supported by the 6 compression tubes. I need to find out the forces on each of the compression tubes when the entire assembly is being subjected to 20g of gravity (20 * 9.81 m/s^2). The results tool just doesn't give us the result! And what is the free body force?! I am using bonding to hold all of the tubes in place, because I don't know how to use bolts!
Our problem with tensegrity: We are using 9 strings, or spokes (like bike spokes) to hold the secondary mirror in place in the middle. These spokes MUST be pre-tensioned so that we can have a rigid structure with high frequency. I'm unable to put these spokes in pre tension. And in the video they are moving like noodles!
Please help us with these issues as we have tried everything we could.
We are students, so if there are any fees that we need to pay, please let me know.
