Abstract:On the basis of rub-impact dynamics equation of rotor system with rub-impact fault, according with the reliability design theory and sensitivity analysis method, the reliability sensitivity analysis method of the rotor system with rub-impact was extensively discussed by applying the random perturbation theory, Kronecker algebra, the fourth moment technology and matrix calculus theory. A numerical method for reliability sensitivity design of rotor system with rub impact was presented. The variation regularities for reliability sensitivity of random parameters statistics characteristic were obtained and the effects of random parameters statistics characteristic on reliability of the rotor system were studied. The presented method provided the theoretic basis for the reliability design of the rotor system with rub-impact. A numerical example demonstrates that the result of presented method is accord with the qualitative analysis, the proposed method is efficient and accurate. |
Transactions of the Chinese Society for Agriculture Machinery (CSAM), in charged of China Association for Science and Technology (CAST), sponsored by CSAM and Chinese Academy of Agricultural Mechanization Science(CAAMS), started publication in 1957. It is the earliest interdisciplinary journal in Chinese which combines agricultural and engineering. It always closely grasps the development direction of agriculture engineering disciplines and the published papers represent the highest academic level of agriculture engineering in China. Currently, nearly 8,000 papers have been already published. There are around 3,000 papers contributed to the journal each year, but only around 600 of them will be accepted. Transactions of CSAM focuses on a wide range of agricultural machinery, irrigation, electronics, robotics, agro-products engineering, biological energy, agricultural structures and environment and more. Subjects in Transactions of the CSAM have been embodied by many internationally well-known index systems, such as: EI Compendex, CA, CSA, etc.
