| Popis: | In the study, measurements of 3D deformations of the flexspline in harmonic drive were performed by applying a digital image correlation (DIC) method. The tests were carried out with the use of physical 3D printed models made of ABS copolymer (acrylonitrile-butadiene-styrene), which ensured sufficient capacity andrigidity of the structures. The findings related to deformations in flexspline, obtained through bench testing, were compared to the results of calculations conducted using the finite element method (FEM). Significant convergence in the findings obtained using the two methods was shown, yet deformations measured in the real-life model were characterized by greater irregularity compared to the corresponding solutions obtained with the numerical method. The results obtained through optical measurement confirm that physical models made of plastics, built using rapid prototyping technology, can justifiably be appliedin bench testing of prototype gear transmissions. |
