Free Body Diagrams – Advanced Utilities to Ease the Process
01/13/2011
By
Jeff Wollschlager – Director, Modeling and Visualization
and
Paul Eder - Program Manager – HW API & GUI Toolkit
Detailed part analysis and optimization involves the creation of sub-models, or breakout models, extracted from global or internal loads models. The creation of these sub-models can be difficult and time consuming using traditional methods. Utilizing Free Body Diagram (FBD) concepts, one can simplify and streamline the understanding, creation and setup of breakout models. FBDs allow the user to understand load paths and to create free body loads of interest for detailed models as boundary conditions (BCs) within a sub-modeling scheme.
FBDs also allow for equivalent force and moment results to be calculated on cross-sections for each loadstep. From these results, Shear-Moment Plots (VMT) can be created for determining maximum equivalent loads. These results can also be used to create Potato Plots for performing loadstep screening in advance of the detailed part analysis and optimization.

Simulating Complex Fasteners and Connections – HiLock Fastener
09/10/2010
By Stuart Sampson
Program Manager – HyperMesh
Introduction:-
Within the aerospace industry, a need arose to create a new fastener to replace the HiShear fastener, more commonly known as a rivet. The prefixed collar of the HiShear fastener limited its versatility. Prompted by this need, the HiLock fastener was designed. The collar of the HiLock is threaded and both the pin and the collar itself were designed to fulfill a wide range of applications and installations. The HiLock fastener also is easier to install and remove, eliminating the need for highly specialized tooling. Along with its expanded versatility comes the challenge to accurately model and simulate the HiLock fastener. Altair HyperWorks addresses this challenge by using the connector technology in HyperMesh to automate the modeling of this complex fastener.
