The comprehensive performance requirements of bevel gear in advanced helicopter transmission system are continually escalating. As a critical component of bevel gear, the design of the spoke plate is instrumental in enhancing its overall performance. Therefore, proposed here is a design optimization strategy of bevel gear spoke plate with integrated multi-topological features. Firstly, the spoke plate area is expanded according to the assembly relationship between the parts. Secondly, topology optimization considering stress constraint and frequency-driven topology optimization are carried out on the expanded bevel gear spoke plate, and the topological features of the optimization results are extracted. Lastly, the bevel gear spoke plate is subjected to an integrated design of multiple topological features, and a novel lightweight vibration avoidance double-layer bevel gear spoke plate structure is obtained. After optimization, the scheme satisfies the strength requirements and the mass of the bevel gear spoke plate is reduced by 16.39%. The first two natural frequencies of bevel gear are increased by 76.52% and 76.53%, respectively, thus reducing the risk of resonance failure by moving away from the excitation frequency. This demonstrates that the proposed strategy significantly enhances the comprehensive performance of bevel gear spoke plate and yields an innovative configuration for advanced bevel gear spoke plate.
