Modeling Compliant Parts: Dealing with Flexible Assemblies

Dimensional Control Systems is pleased to present a webinar on solving flexible assembly issues in 3DCS.
 
TROY, Mich. - July 22, 2013 - PRLog -- Dimensional Control Systems (DCS) is excited to be presenting a live webinar on “Modeling Compliant Parts: Dealing with Flexible Assemblies”, to be presented on July 25th, at 11 am EST. There is no cost to attend this event. A recording of the webinar will be emailed to registrants shortly after the event.

The webinar features CAD simulation and analysis, using 3DCS, both the CATIA V5 integrated and the Multi-CAD version.  DCS’s technical team, consisting of Elizabeth Prentice and Saurav Kakar, will go through the solutions to two sample dimensional problems. Both of these issues stem from the effects of manufacturing variation on flexible parts and assemblies.

Most assemblies deal only with rigid body parts, those that do not flex or bend during assembly and manufacturing. However, when compliant parts are present in an assembly, as is often the case in automotive and aerospace manufacturing, it is important to take into account the flexibility of these parts during production.

3DCS Compliant Modeler, an Add-On to 3DCS, allows the analysis of flexible and compliant parts, utilizing FEA Mesh data, as well as modeling clamping, welding, over-constrained assemblies and other assembly routines.

This webinar will examine two use cases in Compliant Modeler. Both of these cases are based on real life examples, but are not using actual customer data.

The first case involves an aircraft wing with applied gravity and point force engine weight. The problem to be investigated: the aircraft does not have enough clearance after assembly between the engine and the ground. If this is not corrected, then it is possible that when the aircraft lands, the wings will flex, occasionally causing engine impact on the runway.

Taking into account both gravity and the force from the engine’s weight, various builds are proposed in order to affect the final ground clearance. Originally determining the engine mount location to be the issue, further analysis found the root cause to be variation within the wing box assembly. See how DCS’s technical team delves into the root of the problem and proposes a solution.

The second case focuses on the final body assembly of a car in an automotive plant. When the hood is fastened to the vehicle body it is connected in three places: the rear corners and the front, center latch. The front latch is used to control the hood to fascia flush, while bumpers are set to control the hood to fender flush. Using 3DCS Compliant Modeler, our team will demonstrate how a bumper process can be simulated and tested in order to determine the optimal location to fit the hood in place.

If you use 3D CAD for simulation or design, this is an excellent opportunity to see how 3D variation analysis can help drive and optimize your designs. For those involved in dimensional engineering, this is a perfect opportunity to see how 3D variation analysis can solve complex issues and do more than simple tolerance analysis.
