Collier Research Corporation has released HyperSizer v6 structural sizing and analysis software for reducing weight, maintaining strength, and improving the manufacturability of complex composite and metallic designs.
""One of the biggest roadblocks to effective composite design is the inability of engineers to adequately explore optimized layups simultaneously with other design variables,"" says Craig Collier, President of Collier Research. ""This results in design inefficiencies and compromises.""
To address these issues, HyperSizer is designed to integrate with FEA solvers in a continuous, automated iterative loop, to ensure structural integrity and enhance manufacturability. HyperSizer can be used from preliminary design to final analysis.
New features in HyperSizer v6 include:
▪ Manufacturability Optimization – The capability to identify, define, and control ply-count compatibility, laminate sequencing, interleaving, and ply-drop minimization.
▪ Post-Buckling Analyses – Automated compression, shear, and compression-shear post-buckling analyses have now been added.
▪ Panel Concepts – Two novel, damage-tolerant composite architectures are now available, providing more structural sizing variables and optimization flexibility.
HyperSizer integrates with FEA software, such as Nastran and Abaqus, and with composite CAD tools, such as CATIA and FiberSIM.
""Given the increasing emphasis on more complex materials, engineers need to improve and automate their design processes to reach even higher levels of efficiency,"" says Collier. ""It's no longer good enough just to spot-check. Each part needs to be examined as a system. HyperSizer allows engineers to more fully explore the entire design space.""
""It's challenging to cut weight while maintaining strength and controlling cost,"" says Tom Ashwill, technical leader in Sandia National Laboratories Wind Energy Technology Department. ""HyperSizer has the capability to systematically optimize the placement of a variety of different materials throughout the blade to maximize load resistance and minimize weight and thus cost.""
Composite products, based on polyurethane technologies from global chemical company Huntsman, are taking centre stage at a design exhibition at the Design Museum Gent, Belgium.
In late November, the 14 project partners in the MoPaHyb consortium developing a modular production plant for hybrid high-performance components wrapped up their successful efforts with a two-day symposium in Pfinztal, Germany.
Alvant says its aluminium matrix composite is proven to offer significant weight and performance benefits for rotor applications found in electric motors, flywheels, fans and turbines.
