Simulating bolted joint connections.

Simulating bolted joint connections.

Simulating bolted joint connections.

(OP)
Hi friends,

Can anybody tell me, How to simulate the bolted joint connections?
I have a casting part which is bolted with another base surface using 4 bolts. I have consider only the casting part to be analysed. Which types of constraints I have to use for this analysis.
Pl. help me.

RE: Simulating bolted joint connections.

dvikas,

If you are a maintenance paying customer, you will have access to these Suggested Techniques on the PTC "Knowledge Base":
All the same techniques used in other FEM software programs are applicable to MECHANICA. I found these threads in the Finite Element Analysis engineering Forum (Forum727):
Try also searching through some of the resources linked in the FAQ: PTC Pro/ENGINEER and Pro/MECHANICA internet resources (FAQ554-468).

Thanks MLoew,

I am working on that assignment & will revert you back, incase I have any problem.

Hi Vikas,

try also spot-welds feature. you will find it on the online help.

RE: Simulating bolted joint connections.

Igor,

Using the spot weld idealization will not impart the loads on the system like these other techniques do. All the spot weld will do is to provide connectivity to the members to be joined.

RE: Simulating bolted joint connections.

The bolted connections on PTC's website are not easy to follow.
It seams they were made in the Stand alone version.
I have tried to follow them in the Integrated mode, they always fail.

Any other suggestions?

RE: Simulating bolted joint connections.

There is new bolted connection functionality in Wildfire. There should not be a need to use these old techniques with the new release of the software.

Fasteners:

Fasteners are now available in Structural and Thermal Simulation. Fasteners simulate bolt or screw connections joining two assembly components.

Benefits & Description:
Now you can easily define bolt fasteners in assemblies by selecting the holes that will be held together by the fastener, and by specifying a material and bolt diameter. No longer is the process long and tedious. For advanced fasteners, you can specify stiffness by spring properties as well as bolt pre-load values. Three types of bolt fasteners are supported:
  • Through bolts in solid models
  • Through bolts in shell models
  • Blind (screw) fasteners in solid models


  • There is a video available.
