Abstract

Here, aiming at limitations of planetary transmission system being affected by error randomness and complex coupling relations to cause difficulty of accurately building an analytical model of system meshing impact, a method to extract system meshing impact from test strain signals by combining Hilbert-Huang transform, wavelet denoising and instantaneous frequency theory was proposed. By designing measurement methods and building test platform, instantaneous change points of strain signal frequencies were obtained, positions of early meshing were determined, and thus system meshing impact was obtained. The proposed method was verified by establishing an internal meshing pair meshing impact analytical model and a finite element analysis model. The results showed that due to test results being affected by external factors, they are larger than theoretical results and finite element calculation results, but the three' trends and regularities are completely consistent; the test extraction scheme here avoids constructing complex mathematical analytical models and effects of system complexity and diversity; the proposed method has advantages of universality, correctness and convenience; the proposed method can provide a basis for real-time shape modification design and dynamic performance evaluation of complex transmission systems.
