Hi,

I am using Workbench to perform a static structural analysis on a knuckle-boom jib arm with man-riding basket. Due to the size of the model I have had to split the assembly into four sub assemblies. Working from the basket end, I am applying all environmental and working loads to the fist sub assembly (the basket), and then using force and moment reaction probes at the connecting face, in order to transfer the force and moment reactions onto the corresponding face of the subsequent model (the boom sections). At the moment I am having to do this task manually for each load case and arm position, which is proving to be very time consuming.

I was hoping someone might be able to suggest a quicker / better way of doing this. I have used the Submodeling feature in Workbench before to import displacements from a larger coarser model into smaller more refined submodel, but I can't see how that could be used here. However this feature did make me wonder if there was a similar method suitable for what I am trying to achieve.

Any help / advice would be much appreciated.

Thanks in advance,

The first thought that comes onto my head is to use sub-structuring.

Hi Martin,

Thanks for that. Sub-structuring. I'll look into it. Sounds like a bit of a stupid question now that I know the answer...

Cheers,

Jon.

I've just seen the price of the CMS ACT Extension. Might have to stick to the long hand method. Unless there's another way of doing this.

Thanks,
Jon.
