Geometrical error analysis of a cold forged AUV propeller blade using optical measurement method
ثبت نشده
چکیده
Accuracy is the key issue in the precision forging. Geometric and dimension errors are the two significant defects found in most of near net or net shape manufacturing process. It becomes more critical for complex part such as an AUV propeller blade. In this study, geometric error was quantified by comparing the blade profile obtained from nominal geometry of the blade and the profile constructed by commercial optical method namely Alicona system.

Twist springback measurement of AUV propeller blade based on profile deviation
Geometrical error due to twist springback is one of major defects found in the near net or net shape part. It becomes more critical for complex part such as an Autonomous Underwater Vehicle (AUV) propeller blade. In this study, twist springback was quantified by comparing the blade and the die profiles obtained from commercial optical technique namely Alicona system. The results show a differen...
متن کاملTime Domain Analysis of the Ventilation around the Partial Immersed Propeller Using Sliding Mesh Method
In this paper a computational method is presented for predicting the unsteady hydrodynamic forces acting on partial immersed propeller (SPP). In order to simulate the unsteady viscous flow around a SPP, a Reynolds-Averaged Navier–Stokes (RANS) solver is used. The time-accurate calculations are made by applying the sliding mesh method. Structured and unstructured mesh techniques are used. ...
