Integration promotes concurrent
engineering
Integration makes it possible for analysts to access CAD master model of composite part in to-be-manufactured state any time during the design process and verify the part meets design specifications.
Vistagy is to integrate its Fibersim software with Ansys' solver technology to achieve improved composite design, manufacturing and performance simulation The integration - available in Ansys 10.0 and Fibersim 3.5 and higher - makes it possible for analysts to access the CAD master model of a composite part in its to-be-manufactured state at any time during the design process and verify that the part meets the design performance specifications
This promotes concurrent engineering for composites and enables design optimisation that results in cost reductions and improvements in part performance.
Initial benchmarks have shown that integrating Fibersim software with Ansys solver technology reduces analysis time from weeks to hours.
"In the past, our customers used Ansys for composites, but setting up a composite simulation for complex geometries can require extensive manual effort", said Mike Wheeler, VP and General Manager at Ansys.
"By introducing the Fibersim to Ansys interface capability, material property information created by Fibersim can be automatically transferred to any model geometry in Ansys almost instantly".
"Working together, our products will make product development more efficient for existing customers in the traditional areas of aerospace and high performance automotive, and will open opportunities and applications in automotive, consumer goods and medical equipment".
The typical composite part design process starts with an analyst using Ansys software to determine the requirements for the initial design based on expected loads, including laminate thickness, ply orientation and material type.
These requirements are communicated to the design engineer who then uses the Fibersim suite of tools, integrated in the CAD system, to design the composite part details while attempting to meet the requirements.
Fibersim then simulates how material deforms and deviates over complex curvature and allows designers to send the master model part definition that resides in the CAD system, complete with fibre orientations and all other details, to the analyst for verification.
This lets analysts model the actual part performance, thus detecting stiffness, warpage or buckling issues due to misalignment of fibres.
If design flaws are found, changes can be made directly to the CAD model using Fibersim.
Closing the loop between the designer and the analyst allows companies to proceed to the manufacturing stage with confidence that the design will meet the strength requirements.
Not only does the integration of Fibersim and Ansys enable part verification, it makes part optimisation possible.
It is easier to pass the complete part definition between the designers and analysts now that several iterations of the part can be performed to achieve the optimum design.
As a result, engineers can begin to take advantage of the performance benefits that composites can provide.
"We believe the partnership between Ansys and Vistagy will help companies capitalise on the potential of working with composites", said Steve Luby, President and CEO at Vistagy.
"Software tools such as these that make it practical to use new manufacturing processes and new materials show great promise in delivering innovative products to additional markets".
"Fibersim enables engineers to design composite parts efficiently and accurately, and ensures that the parts can be manufactured".
"Ansys ensures that the part will perform properly once it is manufactured".
"These two products working together reduce the risk of using composites for new applications".
