Hello everyone,
I was working in R&D at an engineering firm and was mostly working with
MSC-ADAMS. I picked up a hobby/research project which involves rigid/flex
modelling and simulating a compound bow. Since MSC-ADAMS is not viable
financially or otherwise, I looked up a few solutions online and I landed
here on this forum. (the other package I found was FreeDyn, which was
closer to ADAMS, but I couldn't find proper documentation, especially for
modelling contact/collision).
I aim to find the output of the system consisting of a compound bow and an
arrow. By output, I mean, the ejecting velocity, range, stress (if we take
up a flex part) etc.
I would try to break my questions into pointers, so it's easy to reply :
1. Is it possible to model a compound bow and arrow using this project?
2. If yes, how steep is the learning curve for someone with basic python
experience? (I do have experience with C++ but it has been a while, python
is my go-to language for day-to-day programming.)
3. Can contacts be modelled fairly easily? (In ADAMS it was particularly
very easy)
4. If I have a CAD ready, will it be useful or do I need to manually
define all the bodies?
5. As my project might involve deformation in some elements, can flex
body be modelled with pychrono? (I saw it being listed in Brief
Introduction)
1. Do we need to find free/open-source FE software or it could be
handled by the library?
2. How difficult would it be?
I would be really thankful if anyone could answer all or even a few of the
queries. This module seems to be promising for learning anyway (project or
not). Hoping to start learning.
Thanks again.
DM
