COMPOSITE ANALYSIS AND
STRUCTURAL SIZING SOFTWARE
 

Customization

HyperSizer is software for automating the types of airframe structural analyses that are performed by a stress engineer using closed form,empirical based, and state-of-the-art numerical solutions. In this regard, HyperSizer contains specialized aerospace structures knowledge and methods and provides a computational framework for performing these non-FEA based analyses. HyperSizer includes the ability to perform many of the different analyses necessary to certify airframes, especially with composites, and does this very rapidly and accurately.

As a framework, HyperSizer can be customized by the end user. Externally HyperSizer can be controlled by other software such as Excel spreadsheets, Mathcad, Matlab, or Model Center. Customization is provided by a fully operational programming object model. This capability is useful for a larger company design system that integrates many software tools together. Internally HyperSizer can be customized by plugging in company proprietary legacy specialized codes such as those for panel buckling or bolt analysis.

Internal Customization

Companies often develop engineering analysis programs to solve particular problems, but many times these codes never get past the level of "research". These codes are often shelved due to their difficulty of use, cumbersome ASCII data input and output, and lack of expert users. HyperSizer now provides an engineering environment where user developed or proprietary analyses codes can be efficiently plugged directly into the HyperSizer analysis and optimization process. HyperSizer Plug-Ins breathe new life into legacy analysis programs, and engineers need only learn one interface that is all encompassing for automated structural sizing, detailed stress analysis, and report generation.

HyperSizer uses a Plug-In standard that defines categories of analysis methods such as composite strength, panel/beam buckling, local buckling, bolted joint analysis, etc. and provides an interface with typical data required for each analysis. For example, bolted joint analysis requires hole diameter, concentrated bolt load, loading angle, etc. In addition, the plug-in standard is flexible in permitting additional, unplanned unique data to be passed between the plug-in code and HyperSizer. These additional variables are entered into the HyperSizer GUI and stored in the HyperSizer database. Once plugged in, the user-defined analysis automatically becomes part of HyperSizer's optimization. Finally, margin of safety results generated by the plug-in are passed back to HyperSizer and displayed in the HyperSizer GUI with all other margins of safety.

Two industry standard legacy codes were integrated with HyperSizer using the HyperSizer plug-in capability and are distributed as part of the software package. Those codes are BJSFM, an analysis program that analyzes open and bolt-loaded holes, and SS8, a Ritz panel buckling analysis tool that analyzes curved panels and allows for general (free, fixed, or pinned) panel boundary conditions.
