Reliability analysis of gear transmission system of aeronautical turbine starter under multi-constraint

摘要

At present, there are some problems in the reliability analysis method for gear transmission system of aeronautical turbine starter, such as low accuracy of finite element model, low efficiency of analysis and low accuracy of analysis results. To this end, a reliability analysis method for the gear transmission system of aeronautical turbine starter under multi-constraint is presented. A 3-D model of the gear pair of aeronautical turbine starter is constructed in UG. The model is input into the finite element software for meshing. The gear transmission of aeronautical turbine starter under working conditions is simulated by defining boundary conditions and applying loads, which provides a basis for reliability analysis of gear transmission system of aeronautical turbine starter. The reliability of the gear transmission system of the aeronautical turbine starter is evaluated by the comprehensive evaluation method, and the reliability of the system is evaluated by the contact of the evaluation results. According to the evaluation results, the reliability analysis of the gear transmission system of the aeronautical turbine starter is realized under the condition of multi-constraint. The experimental results show that the proposed method has high analysis efficiency and high analysis accuracy.
