运用模糊论中二级模糊综合评判法，对直齿圆锥齿轮传动设计中诸影响因素的 模糊性进行了定量描述和处理，建立了以体积最小为目标的模糊优化设计的数学模型 并获得了最优解。算例表明，模糊优化设计是一种符合客观实际要求的科学的设计方 法。
The fuzziness of the influencing factors in the design of spur bevel gears is quantitatively described and dealt with using the second level fuzzy comprehensive evaluation method in fuzzy theory. The mathematical model of the fuzzy optimal design with the minimum volume is established and the most optimal fuzzy mathematical model is obtained Excellent solution. The examples show that fuzzy optimization design is a scientific design method that meets the objective and practical requirements.
