摘　　要：在满足传动可靠性的条件下,针对航空弧齿锥齿轮传动要求最大限度地减少体积、减轻重量的问题,提出了可行域内目标曲线逼近的优化方法,建立了弧齿锥齿轮传动可靠性优化设计的数学模型;并采用Matlab软件编程的方法,开发了一套弧齿锥齿轮传动可靠性优化系统,对于提高可靠性设计的效率和优化都有较好结果。在此基础上,以一对航空弧齿锥齿轮为例进行了可靠性优化。结果表明,利用该系统得到了离散最优解,实现了航空弧齿锥齿轮传动体积最小化。For minimizing the size and weight of an aviation spiral bevel gear transmission,an optimization method of target curve approximation on the feasible region was proposed,and the reliability optimization mathematical model of curve-tooth bevel gear was established.In addition,a curve-tooth bevel gear transmission reliability optimization system was developed by Matlab programming,which was good for improving the efficiency and reliability optimization design of the aviation spiral bevel gear transmission reliability.On this basis,taking a pair of aviation spiral bevel gears as an example,the reliability optimization was carried out.The results show that we can obtain the discrete optimal solution and realize the volume minimization of gear transimission by using this system.
