Connections in Radioss car assembly

Radioss Geek

1. How to connect moving components like tires with axles?

2. Connections between dissimilar material components like glass with doors?

3. How do we decide connection representation for a weld joint.? For example a spot weld connection can be represented as a Hexa element or as a spring element, so how do we choose?

4. What are the necessary properties we need to input for a weld connection in order to represent the connection properly ?

5. How do we decide the stiffness of the spring element? How does it affect the crash analysis if we represent all weld joints as springs and thus overall stiffness increases?

Hi

 

I imagine that all these question are related to method you need to develop

If it helps there is  Radioss model in the model library.

like this one : https://community.altair.com/community?sys_kb_id=95b7629c1bcb1c50a5f742eddc4bcb43&id=kb_article_view&sysparm_rank=1&sysparm_tsqueryId=db164eb8db99f010e8863978f4961928

that can help you on modeling, but ultimately you will need to decide on the methods that best represent the physics you need to evaluate.

I hope this is helpful.
