Best software and training lifting + metal structures

Simulation
1

Hi all

Currently employed in a special machines design office using Solidworks, I realize that the software is not really optimized for lifting or metal structure calculations.

I would like to learn from those who are in each profession what software(s) you use and what training you have received to be able to work effectively?

On the soft side, I was told about Ansys or advance design for the structure. Nothing about lifting or structural or lifting training.

I am looking to deepen my profession in this direction but have no mentor in my entourage to guide me.

Thank you all

Hello

The formation in the steel structure is quite different from that of anything related to lifting. For structures today in the field of BIM (Building Information Modeling) and if you don't want Autodesk's gas plant, you can look at TECLA, which is more affordable when you have little training.

That said, the software will constantly ask you to make technical choices (type of connection for example), but if you don't know what it's all about, you'll be in trouble.

So for the training there is literature but above all there is the evening training (CNAM for example). In my opinion, it takes two or three years in evening classes to reach a sufficient level of knowledge (like a master+) with a prerequisite in RDM. Today, we are talking about metal architecture because of the incredible shapes that are made

For everything that is lifting, it seems to me rather to be an engineering level with specialized additional training because there is much more question of drastic standards, than in mecha all things being equal.

Our colleague @m.blt, who is also a teacher, will be able to tell you more about the subject.

As for Ansys and the like, it's simulation software that can tell you what's correct or not, but if you haven't done a correct build, the simu can't do anything for you.

You should specify your objective a little, knowing that you can't run two hares at the same time: they say in the generally well-informed countryside.

From my point of view, there will be 852 times more outlets in the construction of metal structures than in the more restricted field of lifting.

Look with the chamber of commerce and industry who will guide you very well towards a training course adapted to your wishes, or towards a service that will help you better define your project.

Kind regards

Hello

As for the metal structures, they are mainly access or working walkways within our complex.

I am well aware that these are quite different disciplines. The problem is that we already carry out these 2 types of sizing within the BE, but not being trained we are asked to take quite huge safety coefficients.

Despite this, I wanted to dig deeper to understand the ins and outs of a more calculus. "regular" in this matter. From what I understand, it is for the moment absolutely not at my level (P2), nor that of my colleagues, and the studies have been going on for almost 10 years...

I'll already find out about all this, thank you

Hello

You can close the topic if you wish by selecting one of the answers.

Kind regards

You can also post one of your structures and we will make you a simulation (on a friendly basis) in relation to the desired safety factor. This will give you an idea of what can be achieved with the Solidworks simulation module.

That's really nice, but it won't solve the fundamental problem of how the BE works here;)

I remember the answers.

Thank you very much!

It all depends on the level of complexity of the gateways. For simple gateways, I use RDM7 free software (https://iut.univ-lemans.fr/ydlogi/rdm_version_7.html).

I cut beam by beam or more simply most of the time by calculating just the main beam. (the longest one that takes back all the weight.).

For this beam calculation I use RDM bending, this is more than enough for these simplified calculations.

For the training, it was my former boss, an auditor at Apave, who had trained me quickly over a few days.

If you have a good basis for simple RDM gateway calculations in one or 2 weeks, you can have the basics to do this kind of small calculation. For the practical training on the other hand I could not guide you since my training was internal.

On the other hand, if a calculation note is requested, > external design office for the calculation and the calculation note.

But for a simple gateway it is rarely asked.

In internal operation we always provide an NDC, I looked at the operation of NCD that we had when providing similar models by external design offices and I'm not too bad, in RDM 6 base as well. As for the lifting, it's still .. tense^^

 

Thank you

The problem I see is more in the knowledge of the standards to be applied, a bit like for pressure vessels.

Insofar as the need is internal, the calculation note is just there to recall the assumptions that have been used.
It is more a training on SW simulation that you need; to be seen according to the standards (especially lifting) if the basic version is enough or if you need to do dynamics.

There you go, I couldn't put my finger on it but that's it. What standards should be applied and according to what method. 

For the simulation part, I managed to negotiate a solidworks training, knowing all the same that by talking to people from other design offices, it's not a panacea for calculation software.

Something like this: CETIM training
Otherwise, you can contactthe control body that is probably involved in your company. They should be able to tell you the codes  and standards to which they refer.
