| 摘要: |
| 根据轴承选择具有很大模糊性这一特点，运用模糊理论中的贴近度原理，把丰收系列拖拉机变速箱轴承的类型选择问题看成是一种模糊模式识别，通过确定工况对轴承“承受径向力的能力”等9个功能评价指标的具体要求，计算出各类型轴承对工况的贴近度，进而由贴近度的最大值选择出与工况最吻合的角接触球轴承。该方法还适用于其他类型的拖拉机及类似车辆。 |

| Fuzzy Selection of Bearing Types for Tractor Gearbox |
|
|
| Abstract: |
| According to the characteristic of fuzziness of selecting bearing type and the approaching principle of fuzzy theory,type-selecting of bearing about Fengshou series of tractor gearbox is considered as an identification of fuzzy model.Through determining nine functional evaluation index including ability of loading radial force under particular condition and calculating the approach different type bearings to particular conditions,then angular contact ball bearing corresponded with the condition can be selected based on the maximum approach.This method can be applied to other type tractors and similar vehicles. |
