IDAC Case Study - National Physical Laboratory

Challenges

Modal analysis of full assembled gas turbines for power engineering:

Represent a complex casing model and a sufficient stiffness and mass model of the rotor

Search for the best solution choosing appropriate model and boundary conditions

Using ANSYS Workbench and ANSYS in combination:

Importing complex models into ANSYS Workbench for preparing the geometry and assembling

Getting a high robust mesh of large structures

Export/switch to ANSYS to build up significant and adequate FE assemblies with added simplified models

By utilizing the advantages of a strong 3-D tool and robust FE system, ALLCAD and its customers can save time and costs by:

Easy-to-use CAD technologies

Stable interfaces for interacting and for external programs

Sophisticated element techniques

Standardization of assembling via macros

Quick post-processing for providing customers with reliable results

Testimonial

"Using the classical ANSYS Mechanical software in interaction with ANSYS Workbench facilitates work on large 3-D models for our customers.

The ANSYS Workbench technology is an improverment for importing, further processing and pre-validating complex 3-D geometries from other CAD systems.

Transferring prepared models into classical ANSYS software allows us to combine different element types along with conventional ANSYS techniques. So large 3-D structures can be extended to adequate assemblies.

To achieve fast turnaround and cost efficiency for our customers, it is necessary to utilize the full spectrum of FEA in structural mechanics and dynamics as well as thermal analysis.

Therefore, our work is validated by our customers' satisfaction.”
