Abstract:

The rapid prototyping process was carried out on the example of an aircraft wheel hub and the key role of information operations performed at each stage was stressed. The design and its verification in a CAD system environment was completed. Parts were assembled and tested on their mutual cooperation. Basing on the model of 3D CAD a model of finite elements method was constructed and the tension distribution analysis was made. Tasks performed, supported by the CAD algorithms, made it possible to generate a final version of the solid model. On its basis, an STL model constituting a base for the process of RP was developed and verified. Using software tools RP processes SLA and FDM were developed. The simulation of overlapping layers was carried in order to eliminate errors in the relevant physical processes. The numerical routines were generated for the apparatus: SLA 250/50 and uPrint. Prototypes of hub were made on the basis of stereolithography techniques and liquid plastic modeling. The coordinate measurements of models were carried out and errors specific to each method were analyzed.
