Case studies and examples

Design and manufacture of satellite antenna reflectors

power iso crack filehippo SatelliteThe shape of the satellite antenna reflector is highly complex, dictated by the required geographic coverage of the Radio Frequency (RF) signal. Reflector design employs specialist simulation and optimisation tools. The final shape needs to be represented in CAD compatible format, while ensuring compatibility with the manufacturing process capabilities.

Measurement Based updating of CAD Models

adobe illustrator cs6 serial number keygen free download Measurement Based updating of CAD ModelsIn the design and development of high-performance products such as turbine blades, it is generally difficult to relate the in-service performance to the specified manufacturing tolerances. For this reason it is highly desirable to perform CAD remodelling of the manufactured part using dimensional measurements, in order to provide an accurate representation of the manufactured geometry. This can then provide input for the engineering analysis tools in order to better evaluate the in-service performance and to correlate the predicted performance with experimental results.

crackhead conf crack vso convertxtodvd 5.0.0.45 In this application, the CAD model was used to optimise the measurement plan and to program a Coordinate Measuring Machine (CMM) equipped with a touch trigger probe. The measured data was then used to update the CAD model while ensuring that various constraints regarding the shape and the modelling entities were satisfied. The updated CAD model was then used to perform aerodynamic simulation corresponding to the manufactured geometry. The main steps in the process and the results involving the blade aerofoil are presented in the figures below.
