Creo Modeling Query

GD_10284521 — Fri, 02 May 2025 09:43:03 GMT

I am currently working on a project and encountering few challenges.

I am confident that your expertise can provide valuable guidance to help resolve these issues.

Project Description

I am developing hook-type clamps designed to securely hold the red tube. Both clamps lock via hooks and are bolted at the leg end to exert clamping force.

Optimal design criteria for the clamps include following:

(Length A) gap must be maintained after Assembly to ensure continuous clamping force on the red tube.
(Length B) Must be at least equal to or greater than the tube size for proper fitting.
(Length C) This length must exceed the clamp thickness to allow the bottom clamp to fit securely inside the top clamp.

(Length A, B and C)-Refer Image

The clamps are governed by geometric tolerances, with a profile of surface tolerance of 1mm along the inner surface. I have attempted to optimize the design manually using a trial-and-error method, creating different models under extreme conditions to meet geometric tolerance and tyring to satisfy all the criteria’s

However, I am uncertain if the design meets all conditions considering GD&T.

I need assistance with the following:

Is there a more efficient method to optimize the design rather than relying on manual trial-and-error?
Is there any method or feature to verify if the clamps will assemble correctly under all conditions within the geometric tolerance range?

The use of analysis features and the Behavioral modeling extension (BMX) would support the automation of varying the parameters within the permissible bounds. With BMX you can run a feasibility/optimization study.

Is there any method or feature to verify if the clamps will assemble correctly under all conditions within the geometric tolerance range?

Maybe, that would depend on how you can define a pass fail criteria in the context of the models. If you can describe the test conditions using relations, then yes it should be possible.
