Three Level Reducer Dynamics Analysis And System Reliability Evaluation

This three reducer from a certain type of ship turret rotating mechanism,Due to manufacturing and assembly errors exist, the performance impact on the turret and the reliability of the gear transmission system impact.This has resulted in the combat capability of naval vessels as well as the reliability can not be guaranteed.This is not only for the ship itself is a huge threat, but also the country’s territorial waters pose a great impact on security.In order to solve these problems need to analyze the three paper reducer under the influence of random errors in the system dynamics. And three reducer system under the influence of random errors in the reliability of the case.By LS-DYNA dynamic analysis software displays the gear reducer overall dynamic analysis, analysis of the system under the action of random errors in a system dynamics model due to random errors will lead to change, so this is also parameterized using APDL language programming, making the analysis process versatility.Use of LS-DYNA doing dynamics analysis of gear reducer, Doing small sample test of the gear reducer to get stress data for fatigue reliability calculation, Extracting the various parts of each test required the maximum stress, the stress distribution obtained and detected with the KS test method for stress distribution and then using Stress-strength interference model for solving the fatigue reliability.This gear reducer gear and shaft with an interference fit.This static analysis using ANSYS to verify the reliability of the interference fit.This paper can analyze the influence of random errors on the system, the system solved the fatigue reliability and validated interference gear and shaft assembly is reliable.
