摘　　要：针对航空锥齿轮薄壁辐板的动态响应及结构振动抑制问题,提出了减振孔型结构优化设计方案。以某型航空弧齿锥齿轮为例,建立了弧齿锥齿轮模型,采用Lanczos法计算了齿轮的固有特性,分析了前6阶固有频率与激振力的频率裕量;用模态叠加法进行了谐响应分析,研究了不同孔型辐板的动态响应特性及其对振动传递的抑制作用;利用正交试验设计、仿真分析,优选了辐板孔型结构参数。结果表明,在等面积、等数量的条件下,三角型、圆型、枕型、腰型四种孔型振动响应依次递减;优化后的腰型孔能够有效抑制振动传递,提高锥齿轮传动的平稳性。In order to solve the problems of dynamic response and structural vibration suppression of aircraft bevel gear thin⁃walled spoke plate,an optimal design scheme of damping pass structure was proposed.Taking a certain type of aeronautical spiral bevel gear as an example,the model of spiral bevel gear was established.The natural characteristics of the gear were calculated by Lanczos method,and the frequency margin between the first six natural frequencies and the excitation force was analyzed.The dynamic response characteristics of radial plates with different holes and their suppression effect on vibration transmission were studied by means of modal superposition method.The parameters of radial plate pass structure are optimized by orthogonal experiment design and simulation analysis.The results show that under the condition of the same area and the same number,the vibration responses of triangle,round,pillow and waist shapes decrease in turn.The optimized waist pass can effectively suppress vibration transmission and improve the smoothness of bevel gear transmission.
